so you have to love zirconia all-ceramic dental

so you have to love zirconia all-ceramic dental

With dental porcelain technology continues to evolve, more and more people to meet the requirements of high aesthetic porcelain teeth continue to emerge. In this paper, I will introduce a new kind of porcelain teeth

- Zirconia dental zirconia all-ceramic tooth has a very busy popular because zirconia all-ceramic dental teeth whitening machines many advantages, people have to love.


        Specifically, zirconia all-ceramic dental main advantages are the following:


        (1) Zirconia dental material density and high strength, flexural strength greater than 900mpa intensity ratio empress2 (cast porcelain crown) 1.5 times higher intensity

Alumina ceramic teeth than 50% higher, a unique resistance to cracking and fracture toughness after curing properties, can be made more than six units of porcelain bridge, all-ceramic system solves all

System can not do Longbridge issue.


        (2) Since the base zirconia ceramic dental crown color is white, it inserts into the neck after a period of time not black dark blue, to solve the PFM

Most difficult problem.


        (3) non-metallic zirconium oxide barrier on the x-ray is no change, as long as the inserts into the zirconia porcelain teeth, skull x-ray to be the future, ct, MRI when they

Not removed dentures, eliminating a lot of trouble.


        (4) zirconia is a very good high-tech biological materials. Superior biocompatibility of various metal alloys, including gold. All-ceramic dental materials on the gums

No stimulation, no allergic reaction is very suitable for use in the oral cavity, to avoid the metal produced in the oral allergy, irritation, corrosion and other adverse reactions.


        (5) zirconia all-ceramic dental materials produced by computer-aided design, laser scanning, and then controlled by a computer program made of polished. So

Perfectly.

dental expert answers scaling will damage the teeth do

In recent years, as people's awareness of oral health continues to improve, more and more patients to dental cleanings for oral health care, but there is a part of the people will ask, scaling it will not damage the teeth for this topic, we Listen to the dielectric strength of dental specialists.


    Dental experts say: every adult teeth at the gingival margin to varying degrees piled calculus, tartar and plaque, which can cause gingival margin hyperemia, edema, easy to cause bleeding gums, if left untreated, can cause periodontitis , periodontal ligament and alveolar bone atrophy gradually ill, fixed tooth tissue will become dental equipments less and less, resulting in significant loosening of the teeth. Therefore, in a timely manner, but in addition to scaling tartar, dental disease prevention and species occurrence, scaling is not a dental drill, will not damage teeth.


    Some people think that scaling will damage the tooth surface tissue, resulting in allergies or loose, dental experts say: this idea is not correct. Scaling is not a drill teeth, it dental Vacuum Former is the use of ultrasonic vibration theory, the plaque, tartar shattered, and the doctors operated to continuously move the working head, just touch the calculus, will not damage the teeth.


    Finally Dental Experts pointed out: scaling is not going to damage the teeth, but the teeth and oral health has a protective effect. So every six months or a year to the hospital scaling, is very beneficial for dental health.

dental fillings disinfectants what

Fill in the dental clinic for teeth, dental surgeons and general decay of our organization will be worn out, remove the decayed part of the ready-hole, and then disinfect them, and finally filling treatment, then commonly used in clinical dental cavities disinfectants, what does.


    Dental experts pointed out that dental fillings used clinically disinfection drugs - silver nitrate: is a strong disinfectants and corrosive. 10% silver nitrate solution for superficial caries cavity disinfection, sterilization is not suitable for deep cavities. 0.1% silver nitrate solution can kill a variety of bacteria; 0.01% silver nitrate acrylic resin teeth solution to inhibit bacterial growth. Since silver nitrate great irritation, not the time will damage the pulp, it is required to use extra precautions. Alcohol: 75% alcohol sterilization strongest, but rarely used in clinical cavity disinfection.

    Camphophenic: Disinfection is weak, but the permeability is strong. Eugenol: a disinfectant, analgesic effect, but the disinfecting capability is weak. Thymol: Disinfection strong in dentin permeability larger, pulp irritation slight, with a mild analgesic effect, is an ideal cavity disinfectants. 0.003% thymol solution can inhibit the dental machine growth of pyogenic bacteria.


    Dental experts pointed out that dental disinfectants main effect is to dentin completely kill the residual bacteria and prevent further development of caries. The specific choice of what kind of disinfection materials, dental hospitals based on the patient's oral condition combined with the patient's physical and mental condition.

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, increasing dental supply companies 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.

do porcelain veneers whitening need pay attention to what


White porcelain veneers do need to pay attention to what?
1 Oral cosmetic physicians often faced with how to choose different for different patients whitening method. For the treatment of choice, then should be considered is the preferred way

More likely to retain the natural tooth tissue, maintain and promote healthy dentition. Doctors should be based on the patient's oral condition, the preferred method of treatment from all the traditional select

The smallest of the teeth operation dental unit price methods, such as microwave shaping, bleaching and bonding composite resin restoration. Sometimes, the best choice even without treatment.
2 porcelain veneer restoration techniques depends on the reliability of the etched enamel matrix, porcelain veneers life depends on the amount of enamel to support it. So finish porcelain veneers

, Be sure to pay attention to replenish the necessary acid intake. In comparison, the effect is difficult to foresee dentin adhesive, especially for repair purposes.

If the tooth preparation tooth ultrasonic tip preparation before or after leaving only a small amount of enamel, porcelain veneers fix it in the short term because micro-leakage or adhesive off and the risk of failure

Will be significantly improved.
3 selection of quick fix repair methods, trying to instantly change the appearance must be very careful when, for more serious and malalignment or discoloration is particularly true for patients

. Some clinical need for an integrated treatment approach, involving orthodontic and periodontal treatment. Using a combination of methods not learn to develop treatment plans will often be relatively

Effect on oral health damage to the patient is relatively small.

tetracycline treatments are available


Tetracycline treatments are available? Tetracycline tetracycline led to a fundamental culprit, we can not change the past, only to calm in the face of reality, for now

In the tetracycline to treat but can be changed to achieve has a bright white teeth, then tetracycline treatments are available?
Dentists say, tetracycline during tooth development is taking a greater amount of tetracycline drug-induced. Tetracycline binding to the tooth tissue, the tooth color, which

Kinds of color for the sun to dental x ray unit promote gradually become darker colored front teeth therefore generally more pronounced than the posterior teeth. Since only the administration during tooth development can lead to hair tetracycline

Students, so now some people "talk dental Vacuum Former tetracycline discoloration" can be described as unfounded. To prevent tetracycline, pregnant or lactating women, and not suitable for children under 8 years old

Use of tetracyclines, 8 years after taking Tetracycline is not significantly affected. Although tetracycline coloring is permanent, but it is not incurable, the most

There are three common approach:
First, the crown restoration: Applies to all tetracycline, masking effect. But need to wear in addition to more tooth structure may cause pulpitis. Some dentists think that to

Avoid pulpitis possible, should be preceded by the crown becomes vital teeth without dental pulp. Currently crown is generally used porcelain crowns, after its restoration vivid color, but the price

High, complex process.
Two, veneers treatment: enamel hypoplasia applicable to those who, but for severe tetracycline stained teeth, ineffective. The treatment needs in addition to a small amount of enamel wear in

Tooth surface mount resin, porcelain and other materials, making higher, shape, color better and affordable. But after treatment, veneers easy to fall off, the teeth can bite hard objects.
Third, the bleaching treatment: This applies to tooth colored light, not accompanied by enamel hypoplasia. Bleaching treatment methods can be divided into inner and outer bleach. Bleaching is bleach

Placed inside the tooth, good clinical results, the disadvantage is that you want to become non-vital teeth dental pulp. Bleach is bleach outside into the tooth surface, the effect is better Bleaching, but without

Damage teeth.

oral Union

Oral is the beginning part of the digestive tract, oral cavity in the evolutionary process of the formation of some highly differentiated organ, adapted to sucking, chewing, saliva secretion, taste and feel the language and other complex functions. Oral known as the mouth, the digestive process involved, helping pronunciation and speech movements, with sensory function, and can be assisted breathing, have important physiological significance, is the daily life of people engaged in various kinds of social activities essential organs. Everyday life, as we speak, are inseparable from the mouth to eat.

   Main features are: chewing, sucking, Intra Oral Camera swallowing, speech, feeling, expression, food intake, participation in breathing. Oral function is under the domination of the central nervous system, relying on the teeth, lips, cheek, tongue, palate and other organs, through the relevant muscle contraction and jaw movement is completed, the masticatory system dental machine is the result of division of labor between tissues and organs.

Pediatric Dentistry scientific knowledge

1 What is the "six old tooth"? Any protection "six old tooth"?
What is the "six old tooth"? Any protection "six old tooth"? In primary molars behind the first permanent molars, since the eruption in children six years old or so, so called it "age six teeth." Just eruption of the "six old tooth" is not very strong, but without the occlusal surface of uneven wear, fissure deep, easy accumulation of food debris and plaque, and difficult to clean, so they are subject to the erosion of acid-producing bacteria, is prone to caries. We can use methods fissure in before the occurrence of dental caries, Tim flat occlusal surface deep fissure, the accumulation of food debris and plaque is not easy to achieve the effect of prevention of dental caries. In addition, the "six old tooth" eruption early, but also quietly last a long in the rear molars, are often mistaken for teeth, dental caries High Speed Handpiece early did not receive timely treatment, until the pain, we have very serious damage from even a teenager would have to be unplugged regret for life. To avoid this situation, you should bring the child to the hospital for checkups regularly. When the judgment is deciduous or permanent teeth can not be a problem, you should go to the hospital for a doctor to help solve the problem.

2 children dentition duration "double tooth" how to do?
Length of time the child dentition "double tooth" how to do? The tooth replacement, permanent teeth have erupted dental supplies and no normal shedding of deciduous teeth, there will be "double tooth" situation. "Double tooth" phenomenon is most common in the lower front teeth replaced. In the absence of the normal shedding of deciduous occupy permanent positions, a new eruption of permanent teeth can not be ranked in the normal position of the dentition, often in the lingual dentition, resulting in tooth malalignment. At this point, should be promptly removed without the normal shedding of deciduous teeth, eruption of the permanent teeth with the power to go back dentition.

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 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.

4 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 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, 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.
