Secant Pile

Secant Pile refers to the use of mechanical grinding holes, casing under pressure, grab the casing soil, between the pile and the pile foundation pit structure arranged in bite-shaped
 
Style. The arrangement of the pile is generally an a pile (plain concrete piles) and a b piles (reinforced concrete piles) spaced, construction of the first construction of a pile after pile construction b, a pile of concrete using ultra retarding concrete, requests must be completed before the initial setting of a pile of concrete piles b.
Construction points are as follows:
(A) for concrete guide wall, dental x ray unit ensuring accurate positioning bite pile to ensure a smooth rig to withstand construction loads.
(2) drilling, dipping first one casing, casing vertical control, using inclinometer casing affixed to the outer wall of the vertical degree detection, detection of deviations promptly corrected. After the casing into the hole with concrete pouring piecewise uprooted.
(3) pouring of concrete, the B Pile A pile due to cutting, the A concrete pile does not reach a state where the strength of the sleeve under the rig cutting grinding action and generates the A concrete pile damage. To this end, the use of anti-A pile of concrete setting time, the A pile of concrete at the end of the initial setting state applied for B-pile construction program. According to tests, retarding superplasticizer SP-type doped after the initial setting time of concrete around can delay to 60h (according to the situation of construction equipment and construction speed determination), ensuring the implementation of the construction program operability. Concrete using catheter infusion, if the hole bottom seepage much water inflow exceeds l m3 / h, using underwater concrete pouring.

Fault 1, a cell phone no water, first check the phone line there is no water, and if there is water that is blocking the phone using end ligation can solve the problem. If the phone line is no water on the check diversion switch. If you do not see the problem on the foot switch controlling water switch has not been opened. After exclusion check whether gas control valve of the gas supply, if the supply on and into the water, dental material water, gas control valve that is the problem, the solution, open the air control valve cleaning the inside of the scale, smeared Vaseline mounted on top.
Fault 2, all phones are not water, first three guns there is no water, no water if it is water or piping problem (solution here is not to talk about). If three guns and water, under normal circumstances is no air control valve of the gas supply on. If the gas control valve on the gas supply, disconnect the air control valve outlet pipe, stepping on the gas pedal to see no water control valve out, if no water, gas control valve dental Vacuum Former that is the question (ibid. solution ). If the water vapor that is integrated in the valve diaphragm adhesions apart and re-installed or replaced to solve the problem.

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 dental supplies 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, 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 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.

120, bleeding gums vulnerable populations?

 Bleeding gums is one of the common symptoms of oral disease. Generally divided into two kinds of localized and systemic: local causes bleeding gums bleeding gums, commonly suffering

Gingivitis and periodontitis patients. These patients often because they do not brush your teeth, or because of an incorrect method of brushing, dental bleeding gums clinically susceptible populations are the following

, Patients should be vigilant.


    Bleeding gums susceptible one: adolescent, because susceptible puberty gingivitis, bleeding gums is also common. Mainly due to poor health habits, coupled with the youth

Of endocrine changes more obvious, so the gum tissue of trace local irritants, easy to produce significant Diamond Burs inflammation, bleeding gums.


Bleeding gums susceptible populations II: mixed dentition period children, often due to CNP, a temporary dentition malalignment, easily lead to gum inflammation, such as pay attention

Oral hygiene, gingivitis can lead to eruption causes bleeding gums.


    Bleeding gums susceptible populations three: pregnancy of women, if already suffering from chronic gingivitis before pregnancy, during pregnancy, progesterone levels, often causing the gums

Spontaneous bleeding, can occur during pregnancy gingival papilla tumor-like proliferation called "pregnancy epulis", easily bleeding.


Bleeding gums susceptible populations IV: risk of certain systemic diseases in the elderly, patients with diabetes because gum capillary hypoxia, decreased ability to fight bacteria, could easily lead to

Bleeding gums infection; addition, some high blood pressure, coronary heart disease in elderly patients, myocardial infarction, thrombosis due vigilance, long-term oral aspirin, if more bleeding gingival inflammation

, Long-term use should be vigilant.


    Bleeding gums susceptible populations five: Long-term bedridden, unable to take care of patients, those in poor oral care is bleeding gums susceptible.


    Bleeding gums oral or physical disorders have to be a signal, the patient should be vigilant, usually pay attention to oral health care, and enhance the overall absorption of nutrients,

Improve the body's resistance to regular oral examination and regular teeth cleaning, scaling, once found dental disease, the standard treatment for early stage.

CS - 160 high-speed turbo power-burning fuse faulty judgment and maintenance

 CS - 160 high-speed turbine was then one of the main equipment. Although many clinics now use both treatment machines, but there are many doctors treat it as a air compressor.

    Cause boot burning fuse for three reasons: bad start relay contacts; starting or running capacitor damage; resin teeth locking cylinder or compressor because starvation line package burned. The first two reasons are more common. After a less frequent cause.

    First check the starter relay, starter relay's role is when the compressor is stopped will start capacitor is connected to the compressor so that the next time the compressor starts; compressor starts after the start capacitor and the compressor is disconnected. With multi-meter relay if the contact barrier instructions to activate the relay contacts burned out. Replace the relay. If the moment there are no new relay, the relay contacts and the original bad is not very serious, you can try to use low-speed mobile polished look contacts are able to solve the problem.

If the starter relay is no problem, then check the start capacitor. Check, we first capacitor discharge resistance welding down between his legs. 1x1k file with a multimeter measuring capacitance, then hands should be placed right moment, then slowly back to zero. If the hands have been the right not to zero, indicating capacitor is shorted; dental x ray unit if the hands are not the right place, indicating an open circuit capacitance.

Run capacitor start capacitor inspection methods and the same, but the magnitude of the swing smaller hands.

What is the principle whitening

Whitening operating time not very long, only 30 minutes. Cryogenic cold, completely avoid the operation process of the tooth nerve stimulation. The main component of the whitening agent hydrogen peroxide

, Bleaching the teeth on safe use for several decades. Hydrophilic gums drugs and no contact whitening process, dental handpiece the tooth structure and the enamel will not cause

Any harm. Disposable, no stimulation, no side effects of the whitening effect lasts more than two years. So is recognized as the most effective and safest whitening teeth bleaching techniques

Surgery.

Whitening teeth do not hurt, no side effects, is a good choice for tooth discoloration farewell
Teeth whitening is a kind of absolute security technology, both on the teeth or soft tissue of the gums will not bring irreversible damage, not for individual enamel development

Liang, cracked teeth, teeth with moderate abrasion resistance, the treatment process will be greater than the normal tooth discomfort, such as pain, tenderness, etc., but will be within 24 hours after surgery

Self-healing, so do not worry there are no side effects teeth whitening problems.

the formation of dental fluorosis is how the

Fluoride is a chemical element, like vitamins, is an essential trace element for human body. Water at 0.5 to 1 mg / l concentration, the development of the teeth and bones

Helpful, if more than this concentration, or exceeding the tolerance dose of fluoride tooth, can cause enamel fluorosis. The higher fluorine content of drinking water, drinking when

The longer, more severe dental dental compressor fluorosis. Dental fluorosis popular all over the world, outside of China except Shanghai, municipalities and autonomous regions are scattered in the treatment of fluorosis areas.
As belonging to a particular dental fluorosis caused by environmental factors, another feature is the calcification of tooth development, fluoride to work. If to 8 years of age, in addition to the third constant

Molars, all of the permanent teeth calcification basically completed at this time, even then migrate to high fluoride areas of life, it will not have a dental fluorosis.

(3) low-tech, technological innovation after the weak. More than 40 domestic pharmaceutical production equipment more than sixty varieties and specifications tableting machine tableting machine. Although,

Every year new products are constantly introduced. But where the real level of technology and high added value of the species are few. Product duplication of development serious plagiarism

Prevalence of a variety of Apex Locator tablet presses up to dozens of manufacturers. To survive, many small-scale pharmaceutical equipment enterprises not only in technological innovation to take "Imitation

"Strategy, some manufacturers even entirely by copying someone else's technology as their technology" innovation ", and some even in the" shoddy. "In order to compete for orders, to

To take measures to keep the prices down, because brand loyalty is low, the price war playing, these brands more disadvantage, will inevitably lead to the design and manufacture of tablet presses down the overall level of

Retreat.

Vast majority of China's enterprises are private enterprises in technology, equipment, personnel and other aspects not have the advantage, seriously restricting the technological innovation of enterprises. Section

Lack of corporate R & D institutions, innovation system is not perfect, the lack of technical innovation and technical personnel, their overall technical strength is not strong, updated technology and equipment research and production speed

Degree is very slow. The most noteworthy is that the entire industry technology professionals are in a "lean" stage. It can be said, is the entire industry talent crisis

Inside spread.

tabletting machine

Tableting machine definition: According to the standard terminology on tableting machine has the following definition:

(1) tableting machine, the dry granular or powdered material through a die into a tablet pressing machinery.

(2) single punch tablet press by a mold for vertical reciprocating tabletting machine.

(3) a rotary tableting machine, dental supply companies the rotation of the turntable are distributed in the sub-molds of a multi-track for vertical reciprocating motion of the tableting machine.

(4) High-speed rotary tablet machine, mold the axis of rotation with the rotary speed of not less than 60m/min a rotary tableting machine.
Classification
Models can be divided into single punch tablet press, flower basket tablet press, rotary tablet press, Asian high-speed rotary tablet machine, automatic high-speed rotary tablet press and package

Core tablet machine.
Basket type tablet press single punch tablet press rotary tablet machine

tabletting machine

The granular or powdered materials into mold hole punch pressed into tablets by a machine called a tableting machine.

The first is a tablet press die components, punches up and down movement of the granular materials pressed into a sheet that said the single punch tablet press machine, after the development of

Electric Flower Basket Tablet into a machine. Both tableting machine works is still a one-way hand-stamper-based tablet, ie lower punch tableting fixed and only the red

Sports pressurized. The tabletting manner consistent with the top and bottom uneven force, causing uneven density within the tablet, easy to produce lobes and other issues.

For existing single tableting machine this disadvantage, a rotary multi-punch tableting machine starts bi born. This punch tablet press down evenly pressed simultaneously, so that the drug

Particles in the air more time to escape the die hole, improves the uniformity of the density of the tablet, reducing the phenomenon lobes. In addition, a rotary tableting machine also has

Machine vibration, low noise, low energy consumption, high efficiency and sheeting weight and accurate.

A rotary tabletting machine is more uniformly distributed on the turntable by a certain sub-die lifting movement in a circular trajectory, the particulate material through the pinch roller pressed into a tablet machine.

The punch speed of rotation with the rotary tableting machine ≥ 60m/min called high speed rotary tablet press, this high-speed rotary tableting machine with forced feeding mechanism, the machine

PLC control, automatic adjustable pressure control tablet weight, eliminate waste film, print data, display downtime and other functions, in addition to tablet weight differences can be controlled within a certain range

Except for chipping, loose lobes and other quality problems can be identified and can be removed automatically.

Pressure tableting machine plate-shaped, initially mostly flat round, after the development of the upper and lower sides of the shallow and deep circular arc shape, which is required for coating. With different

Type tabletting machine dental unit development, oval, triangular, oblong, square, diamond, circular and annular tablets follow. In addition, with the continuous development of formulations, due to complex

Fang preparation, timed release formulations requirements made double, triple, and other special cored tablets, which are required in a special tableting machine to complete.

With the development of market demand, tableting machine increasingly wide range of application is no longer confined to mere repression, the medicine tablet, but also a wide range of pressing security

Health food, veterinary tablets, chemical tablets: such as mothballs mothballs, washing block, triazolam block, art powder, tablets and other pesticides, food tablet: chicken pieces,

Radix block, Divine Comedy tea blocks, biscuits and so on.

Tableting machine working process

Tableting machine working process can be divided into the following steps:

1, the lower punch punch position (its working position upward) into the Central die hole in the bottom die hole, seal the hole bottom mold;

2, the use of the feeder to the drug filling the die hole;

3, on the red punch position (its working position down) from falling into the upper hole in the mold die hole and down a certain stroke, the powder into tablets;

4, on the red ascend out of holes. dental compressor Undershoot rise will die hole in the top of the tablet, to complete a tabletting process;

5, the punch down in place, ready for the next fill.

What is the dental implant

Dental implant is an implantable bone tissue in the lower part of the structure as a basis for support, retention edentulous upper dental prosthesis restoration. It includes support for the lower part of the implant

And the upper dental prosthesis in two parts. Dental implant artificial materials (such as metal, ceramic, etc.) made implants (generally similar to root morphology), organized by surgical implantation method

Inside (usually on the lower jaw) and get solid bone tissue retention support through special device and connected to support the upper dental prosthesis. Dental Implants can be obtained with the day

However, tooth function, structure and aesthetic effect is very similar to repairing effect, has become more and more choice for patients with missing teeth restoration.
Implant System
Planting system usually denture teeth based on the implant material, shape and structure, surface structure and connection method for classification. Oral Implantology Oral contemporary clinical practice makes

Implant material, and implant morphology tends simplification. Mainly by four implants made of commercially pure titanium, threaded cylindrical, root-shaped implant with its unique advantages of dental implants

Has become widely accepted within the implant forms. Studies have shown that moderate rough surface structure and surface area can be increased implant osseointegration. Therefore, the project

Clinical use before planting system is generally obtained through various different surface roughness of the rough surface. With the top of the implant by means of a prosthesis

The structure is connected mainly divided into external and internal connections connecting the two.
Cropping systems commonly used in clinical usually consists of three parts:
1 implant: is implanted within the bone part, is still popular preform produced by different manufacturers implant shape, length, diameter, surface treatment, etc.

Not the same. But, in any case, must be biocompatible implant excellent material such as titanium, bio-ceramics production. So far, titanium dental implants is still

Material of choice. Titanium is a rare metal, periodic table of 22, an atomic weight of 47.9, a specific gravity of 4.5. Purity can be divided into four by, four hardest but the toughness is less than 1

Level. 4 titanium containing more than 99% and 100% of pure titanium can not be used nor economical. Most of the commercially pure titanium dental implants is that four titanium. Now widely recognized that

: Made with pure titanium bone implants can produce good osseointegration, its shape may be cylindrical, conical, can be threaded, threaded or not; surface

Etching, sand blasting or surface coating of titanium ions preferably a rough surface, because the rough surface of the implant and bone cells can increase the contact area.
2 abutments: Is part of the implant through the soft tissue, usually with screws to fix it to the implants. It can be the use of prefabricated components, or use the personalized

The production of components. Materials used in making the base station also need excellent biocompatibility, such as: titanium, precious metals, zirconium oxide, etc., and processed into a suitable shape, and high

Surface finish to protect the soft tissue health.
3 Superstructure: refers prosthesis usually has the crowns, bridges, brackets, attachments and other structures. Compared with conventional dentures, implant through a standard pre-

Components easier and more dental compressor accurately through the base station will connect the implant prosthesis.
Implant-supported dental prosthesis type
Including dentition defect types used in implant-supported crown, bridge repair, denture repair using various implant-supported fixed and movable

Repaired. Implant prosthesis connection with the main use screw-retained and adhesion retention in two ways.
Dental implant adapt to the crowd
Individual missing teeth, missing teeth area planting bed properly.
Most tooth loss, intends to use fixed partial denture, to reduce the gap of missing teeth abutment ends of the burden of the middle need to implant abutments.
Denture teeth, missing teeth absorb severe alveolar ridge can not bear the load of the denture base.
Full mouth tooth loss, viable overlay or full mouth full mouth fixed implant restoration.
Long-term dangers of missing teeth
Tooth gap appears: a long missing teeth, close to the teeth will tilt the jaw teeth elongation, dentition destroy the integrity of the passage of time, the remaining teeth are gradually thinning

Open to lose a good close contact, could easily lead occlusal function disorder that.
Masticatory dysfunction: Missing teeth remaining after a series of changes, so that the original good occlusal relationship changed due to the effective functioning between the remaining teeth area is reduced,

Masticatory function decreased, missing a first molar full mouth chewing function will be reduced about 30%.
Alveolar bone atrophy: If missing teeth too long, there will be varying degrees of alveolar bone disuse atrophy, and with missing teeth prolonged increase, this will give late denture repair

Complex facial appearance and maintaining coordination enormous difficulties. Recommended reading: Ten Advantages of dental implant inventory
Affect pronunciation and appearance: Tooth loss can cause wrinkles increase the appearance of aging, speech is unclear. Eventually becoming restoration, teeth tilt and elongation would prevent normal jaw function

Able to exercise, often appear in the joints, pain and limited mouth opening, etc. temporomandibular disorder that relationship syndrome.
Dental implant treatment
Including: clinical examination and imaging studies, diagnosis and treatment planning, surgery, dental implants and production and repair and maintenance of prostheses. According kind

Implant placement and tooth extraction time, implant surgery can be divided into immediate implantation, delayed immediate (within 3 months after tooth extraction) and delayed implant (tooth extraction after three months and longer).

According prosthesis and implant loading time relationship, implants can be divided into immediate loading, early loading and delayed loading.
Complete implant surgery to implant wear this stage, but the long years of implant short. Implants, you need to follow your doctor's required to maintain

Oral hygiene and regular (three months, every six months, or every year) review. If subjected to a number of factors may occur prosthesis off, porcelain breakage, fracture, in order to

And abutment screw loosening, implant breakage and other mechanical complications; and bone resorption around the implant and other biological complications. Seriously affect the restoration, aesthetics, the need to

Surgical treatment or even remove the implant.
Above is about dental implant related presentations, I hope the majority of the friends help. Aesthetic Dental experts also said dental implant is a prosthesis with

"High, fine, sharp" features technology, only those with a high standard of technology and equipment conditions of professional bodies in order to carry out this operation, and this must be engaged in professional

With oral medicine knowledge and skill of the professional system strictly skills, it is recommended if you need dental implants, please choose a professional regular hospital. If you have any questions, please contact

Online experts.

the production of all-ceramic dental materials which have

Yes called all-ceramic dental cosmetic teeth in the classic, is the darling of many stars beautiful teeth. Naturally, this high-tech all-ceramic dental porcelain teeth, its price is not cheap.

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, acrylic resin teeth 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 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, 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.
