long-term unexplained toothache Please note cracked teeth

Long-term unexplained toothache may be provided by cracked teeth caused because crack cracked tooth dentin structure constant depth, while the non-physiological crown surface hairline cracks often difficult to detect and is ignored, so long as the reasons found unknown toothache, clinicians should be given adequate attention, check for cracked teeth.
Cracked teeth occurred in the maxillary molars most mandibular molars and maxillary second premolar; significantly more than the first molar second molar, mesial palatal tip (ie, bear the greatest work of occlusal force tip) more likely. Teeth withstand stress concentration occlusal force itself cracking strength is low, cusp inclination large force trauma teeth are cracked teeth fracturing factor.
If the elderly molars dental steam Sterilizer and bicuspids for a longer time chewing pain and cold pain, irritability history, or bite causes pain in a particular area, and there was a history of injury Ge hard objects that may occur teeth hidden crack. Characterized as follows: occlusal surface cracked coincide with developmental groove and extends over the edge of the ridge; cracked iodine can be stained or radiographic examination see the shadow of deep fine tooth body with the same name as the teeth often symmetrical jaw occurred; suffering occlusal abnormal wear and face steep cusp, there are side percussion pain and biting pain clinics; often cracked at pigmentation, secondary pulp hyperemia, pulpitis, pulp necrosis and periapical inflammation.
For superficial cracked, no obvious symptoms, pulp vitality normal for occlusal adjustment therapy, can also be prepared hole, rubbed crack for preventive filling; For deep cracks or endodontic lesions, in endodontic treatment, while a large number of adjustments cusp slope, completely remove the teeth are exposed fracturing force, dental machine after treatment in a timely manner crowns; endodontic treatment started to do with ring glue to protect the crowns, endodontic treatment should be finished in time for the full crown restoration is essential.

what is the cavities

1 What is the formation of cavities?
   There are four conditions for occurrence of dental caries: bacteria, food, teeth, time. Under normal circumstances, the people of the many oral bacteria, there is a acid-producing bacterium which is also known as cariogenic mutans bacteria. When the food residues present in the surface of the teeth for a long time, cariogenic bacteria and food carbohydrates will react to produce acid, these acids react with the enamel, making demineralized enamel surface, softening, disintegration, forming shallow cavities, then the general feeling no pain, not easily found. dental supply companies If this time is not treated, cavities will grow larger and more deep, superficial damage to the dentin, then eat hot and sour spicy food, the teeth will feel sore. If you still ignore and undermine the pulp, causing pulpitis, there will be a spontaneous severe pain.
2 teeth with holes is not to wait for the pain to fix?
    Not. The teeth have holes to fill in time, you should not wait until the pain to fix. Once a toothache, you need to kill the nerve to do root canal treatment, so that not only the treatment of complex, and the cost to increase, more harm than good. So to the problem in the bud, put it to get rid of, do not wait complexity of the problem, and then solved.
3 teeth hurt too nervous to kill you?
    Depending on the circumstances. Teeth hurt does not mean there is no problem nerves, according to the doctor checks to determine the state of the pulp symptomatic treatment. In general, the pulp is infected, you need to remove the pulp (ie kill nerve) is more likely.
4 teeth have holes, why was it not hurt?
    The outermost layer is called dental enamel, which is no distribution of nerve endings. When cavities located on this floor, people generally do not feel pain. Enamel called dentin layer below, and its distribution within the nerve endings, so it is sentient. Development of this period will not be spontaneous cavities usually pain, but encountered cold, hot, sour, sweet pain can occur when stimulated, more obvious when cold, when the food embedded into cavities also occurs pain. If cavities deeper cause chronic pulpitis or pulp necrosis and chronic periapical, the teeth but not too painful.
5 How to prevent cavities produced?
    First, develop dental handpiece good oral hygiene habits is the most important. Brush your teeth after a meal before going to bed, to develop the habit of flossing, thus removing the food this cariogenic conditions. Secondly, the use of fluoride toothpaste for teeth. Fluoride and calcium binding in the tooth can enhance the ability of acid-resistant teeth. Third, there are some teeth, structural defects, such as deep fissure. Sealant can be prevented. Another irregular teeth can easily lead to clean difficult, orthodontics can solve this problem.

new growth two front teeth do not rely rope how to do

3 new growth two front teeth do not rely rope how to do?
New growth two front teeth do not rely rope how to do? New growth often appear dentition maxillary two gates (incisors) teeth between the large joints, can not move closer. Parents do this very anxious. It can be divided into two situations: one is temporary and normal phenomenon in early mixed dentition, the gap with both sides of the lateral dental Composite incisor and canine eruption will gradually disappear; Another situation is caused by pathological factors, such as: two incisor teeth big ambush between multiple teeth exist, the gap between the front teeth does not go away, should go to the doctor immediately. Therefore, when the two front teeth delays closer, they should seek help children dentist checks, such as abnormal, need early treatment.

caries can be prevented? How to prevent tooth decay

Caries can be prevented? How to prevent tooth decay? As long as a causal factor in caries removal, tooth decay is completely preventable. First, remove the tooth surface plaque, maintaining good oral hygiene is the key to prevention of dental caries. Oral hygiene should begin when a child is born to start. Although there is no time teething babies, parents should also like the same day to the children for the children wash bath scrub mouth. Method, the parents wash their hands after the index finger wrap gauze dipped in boiled water for the children scrub oral, daily morning and evening. As the child's deciduous teeth eruption, use brush with rubber fingers for the kids brush their teeth. 2-2.5 year-old child to be substantially complete eruption of deciduous teeth, the gradual transition to a toothbrush for kids with children brush their teeth. Start with a toothbrush when brushing your teeth, you can only use boiled water or salt water, wait until the child learns to gargle, spit out the toothpaste when you can, use fluoride toothpaste for Apex Locator children brush their teeth. With the growth and development of the child until the hand movement coordination improved in the 4-5 years old (children learn to wash handkerchief) to teach children brush their teeth, to school-age children, the so children can brush their teeth. At this point, even if the child can independently brushing teeth, parents should always check to help children develop good oral hygiene habits. Children should normally be a simple and effective "vertical brush method", namely: along the long axis of the teeth as we brush comb, like brushing teeth, not only the surface, but also the gap between the teeth brushing. From the upper teeth think the next brush from the bottom like on the lower teeth brush, brushing teeth, not only outside, but also should be brushing teeth occlusal surface and near the inner surface of the tongue. Brush each part should be repeated 8-10 times, carefully brush the teeth again, take 3-5 minutes. Develop good feeding habits are another important way to prevent dental caries. While ensuring the growth and development of children under the former title nutritional balance, reducing sugar intake. On infant milk and drinking water, sugar in moderation, do not put too much sugar, but can not use sugar and sweet drinks instead of plain water to feed their children. For infants less than 1 year old night-feeding should put less sugar, preferably hold sugar. Children over 1 year of age, should reduce the number of feedings at night, gradually transition to night without feeding. Children aged 2-2.5 essentially complete eruption of deciduous teeth, you should disable timely bottles, switch to drink from a cup and drinking milk, excessive use of bottles of oral health. In addition, should help children develop good eating habits, regular fixed by law to eat, eat more fruits and vegetables and other natural foods crude fiber. Because fiber foods during chewing on the tooth surface and the cleaning effect of friction, medically known as "self-cleaning effect." Chewing crude fiber foods, like washing - with a dish cloth, like its mechanical action attached to the tooth surface dirt can be removed, and massage gums, dental health benefit, dental Composite and promote jaw development. Meanwhile, the child should be to reduce the amount and frequency of snacking, eat biscuits, cakes, jams and other refined sugary soft foods. Especially at night after brushing can not eat anything. A good diet is not only beneficial for the child's teeth, but also for general health benefits for life. In addition, we can also enhance the hardness of the teeth and improve the structure of the tooth surface defects, and enhance resistance to the teeth against dental caries. In the Beijing area such as low-fluoride area, with a fluoride toothpaste to prevent dental caries cost-effective method. Fluoride is a chemical element.

What is the dental implant

Dental implant is a kind of implant bone tissue within the lower part of the structure as a basis for support, retention of the upper dental prosthesis missing teeth restoration. It includes a lower support implant and the upper dental prostheses in two parts. Dental implant artificial materials (such as metal, ceramic, etc.) into the implant (generally similar to root morphology), the surgical method implanted tissue (usually on the lower jaw) and get the bone tissue strong retention support through special device and connected to support the upper dental prosthesis. Dental Implants can be obtained with the natural tooth function, structure and aesthetic effect is very similar to the repair effect, has become more and more edentulous patients preferred restoration.
Implant System
Planting system usually based on the implant material, shape and structure, surface structure dental needle and connection method for classification. Oral Implantology clinical practice makes contemporary dental implant material, and implant morphology tends homogeneity. Implant consists of four commercially pure titanium steel, threaded cylindrical, root-shaped implant with its unique dental implant advantage has become a world widely accepted implant forms. Studies have shown that moderate rough surface structure can increase the implant surface area and osseointegration. Therefore, the current clinical use implant system is generally through various surface treatment obtained by different roughness of the rough surface. Implant and its upper prosthesis through certain structural phase connection, divided into an outer join and inner connecting the two.

loose teeth clinical assessment

1. Physiological loose teeth
Normal teeth have a certain degree of physiological action, mainly in the horizontal direction. Primary or tank mobility refers to the teeth in the tooth socket mobility, in order to force the teeth after periodontal ligament by different groups arising from changes in the direction of mobility. Secondary mobility refers to the teeth by the external force of about 500 pounds by the crestal alveolar elastic deformation and extrusion coronal soft tissue arising from mobility.
2. Clinical evaluation of loose teeth
I degree: Horizontal loose over physiological mobility, but <= 1mm;
II degree: Horizontal mobility> 1mm
III degree: clear horizontal and vertical loose.
3. Pathological factors loose teeth
Loose teeth decision factors include the degree of alveolar ridge height, periodontal ligament space width and root shape.
Generally, dental compressor loose teeth on the common factors are: periodontal disease, periodontal attachment loss, alveolar ridge absorption, early contact, occlusal trauma, apical lesions, dental trauma, root crack, root resorption, such as bruxism.
4. Adaptability cases of loose teeth and loose teeth clinical assessment
Adaptability loose teeth include the following three conditions: (1) normal alveolar bone height, gap widened periodontal ligament. (2) reduced the height of the alveolar bone, periodontal ligament space is normal. (3) repeated over a period of exploration to tooth mobility is essentially the same, but often widened periodontal ligament or associated with angular bone resorption, and no other pathological lesions, a description of the X-ray changes when loosening and past commitments excessive bite force have been adapted, the lesion is no longer increased. , What we called "stability loose teeth." Stability is generally believed that inflammation is not accompanied by loose teeth without treatment. Constantly aggravated sexual loose teeth and accompanied by further destruction of the alveolar bone teeth, you should promptly conduct a comprehensive assessment, dental canal control the corresponding periodontal disease, as well as the appropriate adjustment or periodontal occlusal splint therapy to achieve maintain health, stable and comfortable periodontal status, play a good oral function.

loose teeth treatment

Clinically, patients with periodontitis loose tooth and the general procedure is as follows: an integrated treatment plan is established, and disconnect without reservation in determining the value of the teeth, the first should be controlled plaque, tartar and plaque retention factors that control inflammation in periodontal tissue . Effective control of plaque and other treatment 3 to 6 months after the re-evaluation. In inflammation control, review when action is still reserved for further observation loose teeth, and according to the following different symptoms and dealt with accordingly:
1 loose teeth increases, the gap widened periodontal ligament, alveolar bone height but normal. dental handpiece More commonly associated with the early contact for adaptive changes. Can be selected occlusal grinding adjustment occlusal establish a balance between the alveolar bone benign alterations, periodontal ligament space back to normal, loose teeth reduced.
2 loose teeth increases, the gap widened periodontal ligament and alveolar bone height reduction. Adaptive changes may still be improved through occlusal adjustment.
3 loose teeth increases, the gap normal periodontal ligament and alveolar bone height reduction. This situation was mainly due to alveolar bone height reduction caused by the general election grind without blending. This should be made clear whether the progressive increase loosening. As for the stability of the loose, and patients no obvious discomfort, can not handle. For the small proportion of patients, if obvious bite discomfort, curing light consider making a good, easy to clean plaque periodontal splint.
4 loose teeth increases, the gap widened periodontal ligament and alveolar bone height reduction. The progressive loosening is pathological, should be looking for the cause, decide on the next treatment. Generally do blending or other co splint treatment. Ensure good plaque removal and control of inflammation is an important prerequisite.

periodontal disease can lead to heart disease

Periodontal disease is one of the common disease, serious problems with people's work and life, dental experts say: periodontal disease hazards can not be ignored, not only can lead to oral

Diseases, but also can cause a variety of diseases body systems, in fact, periodontal disease can lead to heart attack from occurring.
Periodontal disease heart disease


    Studies have shown that oral bacteria can enter the blood circulation, leading to the heart and arteries by periodontal pathogenic bacteria contamination. Long-term exposure to these bacteria, the arteries

Chronic inflammation, High Speed Handpiece increasing the risk of myocardial infarction and other cardiovascular diseases.


    Periodontal bacteria cause cholesterol in blood cell binding with the ester, the formation of thrombus blocks. These clots can lead to atherosclerosis, stroke, ischemic heart disease and crown

Artery clogging heart formation. If heart disease patients receiving periodontal treatment, the heart condition will improve.

    Visible, gum disease if not treated, can lead not only to tooth loss, while the heart can cause a variety of diseases, so experts say: Once suffering from periodontal disease

, Should go to regular professional dental hospital, under the overall guidance of professional dental x ray unit doctors systematic, standardized treatment, while daily life should pay attention to the overall diet

Absorption, enhance the body's resistance, regular oral examination, every six months or a year, once a teeth cleaning.

all-ceramic dental system to recognize the advantages and disadvantages

 Do porcelain teeth on the premise that good oral conditions, retention of teeth strong enough to make porcelain. For an array of ceramic types on the market, the Swedish all-ceramic

Tooth is undoubtedly one of the most outstanding. You know what is porcelain teeth? Porcelain teeth with porcelain teeth do any different? What are the advantages and disadvantages of porcelain teeth do? These are very

Multi initial all-ceramic dental patients should have doubts.

In recent years, all-ceramic porcelain denture teeth restoration has become a new fashion of modern cosmetic dentistry, especially adapted to severe tetracycline stained teeth and tooth missing persons.


    Although all-ceramic dental technology has many advantages, but its technical requirements are high, the doctor must have a high clinical standards in order to prepare the tooth to the appropriate form

, All-ceramic restorations bonded also require special materials, meaning that only a high level of restoration doctors in order to grasp all-ceramic dental restoration techniques.


    All-ceramic dental porcelain material has good biocompatibility, will not cause the gums dyeing and allergies, no adverse effects on the human body, as technology continues to progress

Step and people's living standards improve, more and more patients will choose porcelain teeth to restore their perfect smile.


    If we say that all-ceramic dental drawback is crisp, and the price is high. However, the all-ceramic dental indications are widely used, can be serious oral dentition, teeth, tetracycline

Teeth, Dental Vibrator fluorosis, dental and various malformations of the teeth, etc. can not be filled through the porcelain to repair.


    These are the advantages and disadvantages of all-ceramic dental introduction. In general, all-ceramic dental or porcelain teeth in the boutique! Many people may think that once human factors, genetic Doctors

Cause now dentition defect, to get this tooth to restore the natural, then there is only one way: all-ceramic dental restoration teeth!

Grip on the mechanics refers uneven surface objects

in biology bite occlusion refers to the normal state when the upper jaw is closed, the upper and lower teeth positional relationship of the column. Most people today are front teeth in the mandibular dentition maxillary dentition before scissor bite dental instruments (psalidodontia); another contrast to a back bite (opistodontia) maxillary incisors and mandibular incisor inclination overlying the top of the ramp cover occlusion (stegodontia) are a minority. Upper and lower jaws of the clamp inconsistent incisors bite (labi-dodontia) in ancient humans is common. There pathological alienation bite (hiatodontia) and so on.

the common engineering accident prevention and treatment measures

⑴ "piping" Handling
"Piping" refers to the process B pile into the hole, because the A uncured concrete piles, still in the fluid state, A concrete pile is possible from A, B B pile into the pile hole intersection. Overcome the "piping" There are several methods:
① A pile of concrete slump should be relatively small, not more than 18cm, in order to reduce the flow of concrete;
② casing bottom nozzle should always be kept a certain distance ahead of the cutting face, in order to create a "bottleneck", to prevent the flow of concrete, if the drilling conditions permit, this distance the better, but at least not less than 2.5m;
③ necessary (in case of underground obstacles ahead of the casing end can not) be within the casing into a certain amount of water through the water pressure to balance the pressure of concrete piles A, to stop "piping" occurs;
④ A pile into the hole process, dental machine should be observed adjacent to both sides of the top surface of the concrete pile B, B is found piles of concrete subsidence, should immediately stop A pile excavation and under the pressure side of the sleeve as far as possible, within the pile to the A side filling or water until it is completely stopped, "piping."
⑵ steel cage floating processing
Because the casing wall and the space between the outer edge of the reinforcement cage is small, in the pull casing when casing reinforcement cage may be floating along with. Preventive measures are:
① A pile of concrete aggregate size should be smaller, not larger than 20mm;
② In the bottom of the reinforcement cage welded steel cage on a slightly smaller diameter than the steel sheet to increase its anti-floating capability;
Positive reinforcement cage installation guide ③ device;
④ must follow the rules for the pouring of concrete.
⑶ drilling encountered stone processing method
If there are more venues there are rules rock band, and we will use the "two stages into a hole method" for processing: the first stage, whether A or B piles pile, first got into the rock face to the earth, and then Remove the hammer grab change from the casing with a hammer drill to punch pile design elevation, into the hole after filling the casing, unplug while filling the side casing, the first stage into a hole filled with soil full; second stage, according to the normal construction method Secant Pile Construction.
⑷ segmented construction joint approach
Often a rig construction progress of the project can not meet the need multi-rig construction segment, which exist prior construction segment joints problems. Using sand pile is a better approach in the construction segment and the segment ends to set up a sand pile (after the sand into the hole filled), subject to this section after the construction joints can be dredged sand filling the concrete.
⑸ pile handling accident
In Secant pile construction process, because B super-retarding concrete pile appeared early condensate phenomenon or mechanical equipment failures and other factors, not Secant pile construction requirements for the formation of normal accidents pile. Accidents pile handling mainly the following situations.
a pan pile unilateral occlusion
A pile into the hole construction, concrete piles B1 its side has solidified, the casing can not rig the normal requirements
 
Cutting bite B1, B2 piles. Approach is to shift the direction of the pile A pile B2 bit, make unilateral cuts B2 pile casing drilling, construction A pile (in addition to cutting the original pile guide wall, and strictly control the pile) and B1 piles and piles outside A Another increase in a rotating pile as water treatment.
b back pile reinforcement
A1 into the hole pile construction, dental canal pile it on both sides of B1, B2 are solidified concrete piles, processing methods as a waiver of A1 pile construction, pile adjustment sequence, continue to the next bite pile construction, pile outside later in the A1
 
Occlusal side increased three piles and two jet grouting pile as reinforcement.
c aside bite tongue and groove
Shown in Figure 5, the pile into the hole in the B1 A1 pile of concrete construction has been found in early coagulation tendency but not yet completely solidified, then continue as normal sequence in order to avoid accidents caused by construction piles, pile on the right timely construction of the A1 a sand pile to reserve bite tongue and groove, to be adjusted to complete before continuing behind the pile construction.

missing teeth bite

Generally missing teeth bite mainly refers to the remaining maxillary dental midline midline is not aligned with the teeth, jaw teeth down side to the inside, which not only affects the appearance of the teeth, but also for the normal functioning of oral and periodontal health and Oral health has a great impact. By U.S. dental correction to achieve good results. Reason

(1) early loss of teeth: there will be lack of space, resulting in crowded dislocation.
(2) bad habits: habitual thumb sucking, licking tongue. Jiao lips, bite things, stretching the lower jaw and the bad habit of swallowing, unilateral chewing habits, etc., dental handpiece can cause a variety of malocclusion.
(3) more teeth: teeth can cause multiple teeth, jaw morphology system dysfunction.
(4) Congenital missing teeth: more development and embryo reasons, mostly for lack of third molars phylogenetic degradation.
(5) deciduous teeth: Individual Dental shedding of deciduous teeth are not overdue, for following the eruption of permanent teeth can lead to the obstruction was an ambush, or misplaced eruption.
(6) Rujian tooth wear inadequate: because children eat too soft, so some nipples more teeth than other tooth wear, and thus higher arch occlusal surface, resulting in premature contact, causing the front or side movement, the formation of crossbite.
Missing teeth bite correction method can be used to solve, but very safe, according to each person's situation to determine the correction techniques and methods, it is best to a regular hospital for consultation.

cleaning teeth - Indications

1 gingivitis, tooth Zhouyan Jie Zhi-Shu is the main treatment for gingivitis, periodontitis treatment is the first step. By scaling technique, the vast majority of chronic gingivitis can be treated, and periodontitis is scaling technique, based on further subgingival curettage and other treatment. Scaling technique is the most basic method of treatment of periodontal disease.
(2) a large number of studies have confirmed preventive treatment, have received periodontal treatment for patients, in addition to maintaining sustained period of self-plaque control, scaling regularly do not clean plaque removal, calculus, is to maintain the teeth Zhou Jiankang, prevent gingivitis and periodontitis occurrence or recurrence of important measures.
3 intraoral preparation before other treatments such as the rehabilitation of missing teeth scaling before surgery to remove tartar, you can make a more accurate impression. Some oral surgery, such as tumor resection, resection of the jaw, dental needle  implant surgery, in order to ensure clean around the operation to eliminate the infection risk.
Scaler - Contraindications

1 using artificial cardiac pacemaker prohibited ultrasonic scaler in order to avoid interference with pacemakers caused by work and other symptoms in patients with heart rhythm disorders.
2 Department of malignancy in patients with gum, not easy to accept conventional scaling, in order to avoid spread of the tumor.
3 with active angina, myocardial infarction within six months as well as episodes of failure to effectively control hypertension and heart failure in patients receiving conventional scaling is not easy to treat.
4 local oral hard and soft tissue inflammation in the acute phase patients (except for acute necrotizing gingivitis) should be scaling again after the acute phase, in order to avoid delay inflammation of blood spread.
5 suffering from a variety of people with bleeding disorders such as thrombocytopenia, leukemia patients, three uncontrolled diabetes, uncontrolled hyperthyroidism such patients should be pre-appropriate application of procoagulant drugs control blood clotting speed to avoid washing teeth bleeding.
6 patients suffering from certain acute infectious diseases, such as acute active hepatitis, tuberculosis, etc., and other diseases should also be stable only after scaling to the hospital.
7 pregnant women before pregnancy should be thoroughly oral treatment during pregnancy (especially in the first three months and three months after) scaling will greatly increase the probability of miscarriage.
Cleaning teeth - teeth cleaning process

1 mouth disinfection: Dental Vibrator the patient with a 3% hydrogen peroxide, 0.12% chlorhexidine rinse solution for one minute to reduce bacteria and prevent the occurrence of bacteremia
(2) Manual scaling / ultrasonic scaling
3 Sandblasting: This is done by adding a special salt for dental further high-pressure water cleaning, removal of pigment effect is more obvious. Teeth pigmentation in patients with less severe, it may not need to be sandblasted, as long as ultrasonic scaling it once.
4 finish: polished with dipped polisher polishing paste or toothpaste tooth surface.
5 on the drug: with 3% hydrogen peroxide solution rinse to thoroughly remove residual debris and granulation tissue tartar control of periodontal bacteria breeding sites.

why scaling

Plaque is the culprit of periodontal disease, after the removal of the tooth surface will be constantly re-formed. Plaque removal is not in place, coupled with mineral salts in saliva gradually deposited, the course of time will form tartar. The calculus makes the existence of plaque in close contact with the tissue surface, causing periodontal tissue inflammation. In addition, the porous structure of tartar can easily absorb large amounts of bacterial toxins and tartar would interfere with brushing. For a long time does not clear, it may cause gingivitis, periodontitis, bleeding gums, bad breath, and ultimately lead to loose teeth, or even fall off and so on.
After the formation of Dental Vibrator tartar can not be removed through brushing. According to different parts of calculus deposition to the edge of the gums as the boundary can be divided into subgingival calculus and subgingival calculus, scaling primarily responsible for the removal of subgingival calculus, but the actual operation gingival sulcus should also be linked with subgingival calculus shallow subgingival calculus be cleared.
Because eating some food and colored drinks, the teeth will accumulate some of the pigment. In the long-term smoking and drinking dark beverages like the crowd, pigment deposition particularly evident, the appearance of the teeth have a great impact. In supragingival scaling process, these pigments will be removed. However, due to the tooth surface is not as smooth as the mirror, so you want to completely remove pigment can not be done, there is always some residual pigment on the tooth surface depressions.
The main purpose is to scaling prevention of oral diseases, rather than simply to look good. By scaling can reduce gingivitis, periodontitis inflammatory condition, but it alone is not a cure periodontal scaling. To cure periodontal disease, should also be performed after scaling further professional treatment.

the control points

⑴ control orifice positioning error
In the above settings Secant Pile Top Construction guide wall (This project uses reinforced concrete guide wall, can also be recycled steel guide wall), the guide wall set positioning hole, the diameter should be bigger than the pile diameter 20 ~ 40mm. Rig in place, check the first one cannula inserted into the positioning hole and require the construction unit is adjusted so that the positioning around the casing to maintain a uniform gap between the holes.
⑵ urge the construction unit controls the vertical piles
According to design requirements, pile vertical deviation of not more than 3 ‰. Secant pile in order to ensure a sufficient thickness at the bottom of the amount of bite, in addition to its strict control orifice positioning errors, but also its vertical strictly controlled.
Pore-forming process to control the verticality of the pile, you must grasp the following three aspects of the work:
① straight cannula degree examination and correction
Secant piles on flat ground before casing straight degree examination and correction, dental machine first check and correct single casing straight degrees, and then will follow the entire length of the pile sleeve configured to connect together for the entire root sheath tube (15 ~ 25m) of straight deviation should be less than 10mm. Detection method: measured on the ground emit two mutually parallel lines, the sleeve is placed between the two lines, and a line for testing the hammer and ruler.
② pile into the hole during the vertical monitoring and inspection
a ground monitoring: ground select two mutually perpendicular directions using the line hammer monitoring above-ground parts of the vertical casing, correct any deviations found. This test in each pile into the hole process should adhere to from beginning to end, can not be interrupted.
b check: After installing each section of casing pressure casing before the next section, we must stop to use the "test loop" in the hole verticality checks, failed when the need for correction, until qualified to the next section casing construction.
③ correction
Pore-forming process, such as found in vertical deviation is too large, the importance of timely corrective adjustments require the construction unit, correcting There are three common methods:
a cylinder with a rig for correction: If the deviation is not greater than or buried casing is not deep (5m less), you can directly use the rig two jacking cylinders and two sliding vertical cylinder adjustment sleeve, you can achieve the purpose of correcting .
b pile Correction: If A pile buried 5m large offset occurs below, you can first use drill cylinder direct correction, such as below standard, can be filled with sand to the casing or clay, while filling side uprooted casing, until enhance the sleeve to the last pass the inspection place, and then straighten casing, check and re-qualified under vertical pressure.
c correction: B Pile A pile corrective method is basically the same, the difference is that the casing can not be filled while filling the same with the A pile of concrete, or they may be left in the soil between piles mezzanine, thus affecting the row Pile waterproof effect.
⑶ ultra-retarding Concrete Construction Quality Control
A pile of concrete retarding time should be based on time to determine the pile into the pile, pile into the pile time and geological conditions of the construction site, pile length, pile diameter and drilling capacity factors. According to bite Piles, A pile initial setting time of T = 3t + K + Q;
Where: T - A pile of concrete retarding time t - the time required for single pile into the pile
K - reserve time, usually 1.0t Q - Night downtime
A pile acrylic resin teeth general preliminary control initial setting time of 60h, the construction in the future be adjusted according to the scene.
⑷ occlusal thickness determination
Engagement between adjacent pile thickness d to select based on length of pile, pile shorter occlusal thickness is smaller, thicker pile longer bite, are calculated as follows:
2 (kl + q) ≤ d - 50mm (which is to ensure a minimum pile occlusal thickness not less than 50mm)
Where: l - pile length d - Secant Pile design occlusal thickness
k - pile verticality q - orifice positioning error tolerance

the common engineering accident prevention and treatment measures

⑴ "piping" Handling
"Piping" refers to the process B pile into the hole, because the A uncured concrete piles, still in the fluid state, A concrete pile is possible from A, B B pile into the pile hole intersection. Overcome the "piping" There are several methods:

② casing bottom nozzle should always be kept a certain distance ahead of the cutting face, in order to create a "bottleneck", to prevent the flow of concrete, if the drilling conditions permit, this distance the better, but at least not less than 2.5m;
③ necessary dental unit price (in case of underground obstacles ahead of the casing end can not) be within the casing into a certain amount of water through the water pressure to balance the pressure of concrete piles A, to stop "piping" occurs;
④ A pile into the hole process, should be observed adjacent to both sides of the top surface of the concrete pile B, B is found piles of concrete subsidence, should immediately stop A pile excavation and under the pressure side of the sleeve as far as possible, within the pile to the A side filling or water until it is completely stopped, "piping."
⑵ steel cage floating processing
Because the casing wall and the space between the outer edge of the reinforcement cage is small, in the pull casing when casing reinforcement cage may be floating along with. Preventive measures are:
① A pile of concrete aggregate size should be smaller, not larger than 20mm;
② In the bottom of the reinforcement cage welded steel cage on a slightly smaller diameter than the steel sheet to increase its anti-floating capability;
Positive reinforcement cage installation guide ③ device;
④ must follow the rules for the pouring of concrete.

b back pile reinforcement
A1 into the hole pile construction, pile it on both sides of B1, B2 are solidified concrete piles, processing methods as a waiver of A1 pile construction, pile adjustment sequence, continue to the next bite pile dental material construction, pile outside later in the A1
 
Occlusal side increased three piles and two jet grouting pile as reinforcement.
c aside bite tongue and groove
Shown in Figure 5, the pile into the hole in the B1 A1 pile of concrete construction has been found in early coagulation tendency but not yet completely solidified, then continue as normal sequence in order to avoid accidents caused by construction piles, pile on the right timely construction of the A1 a sand pile to reserve bite tongue and groove, to be adjusted to complete before continuing behind the pile construction.

bionic beauty crown correction

The situation is different occlusal dislocation, resulting in varying degrees of facial appearance and dental function disorders, timely orthodontics is the key, to choose their own method can effectively improve the speed of orthodontics. Nano-bionics beauty crown can precisely adjust the upper and lower teeth occlusion. It is more integrated into the bionic design concept, the focus on dental aesthetics more dental x ray emphasis on the premise of natural tooth structure, complete, and highly compatible with various parts of the mouth, the use of environmental health absolutely no toxic residue of the material, shaping and real teeth as excellent Mechanical properties of chewing teeth. Is misplaced by hundreds of thousands of European and American teeth, dental deformity in patients has been recognized professional repair tools, compared with traditional methods, nano bionic beauty crown has no extractions, no pain, strong teeth, gums do not appear for years after the black line, and gums highly compatible with real teeth without second advantage.
