Principles of tooth bleaching

Principles of tooth bleaching tooth bleaching agent used is the main component of 10% concentration of carbamide peroxide, carbamide peroxide 3.3% in the decomposition of hydrogen peroxide, hydrogen peroxide is easy to penetrate into the What is contraindications ultrasonic scaler enamel and dentin, the pigment molecules which material is broken down into small molecules, so that the teeth color lighter.

Bleaching:

Bleaching is currently the main points clinics and home bleaching. Clinic is the use of high concentrations of bleach bleaching drug in a special light source, generally 1 to 2 times a day, each about one hour. Household bleach is to take the denture impression making a thin dental equipment personalized tray, tray, add a day to drugs, wear 4-6 hours a day, lasted about a month's time.

Tooth bleaching is indicated:

Best adapt to the official partial bleaching and partial orange brown discolored teeth, the teeth increase with increasing age the best yellow, tetracycline for mild, moderate the effect of dental fluorosis.

Not to hurt the teeth whitening methods

Many of my friends will have this question, we know that the most commonly used method is to do teeth whitening, then use will not damage the teeth whitening? We take a listen to the experts this introduction.

Experts point out that tooth whitening technology is the wavelength range 480-520nanometer between the high-intensity blue light, through the optical fiber transmission, multi-layer coating 30 by two special optical lens, and then through a special optical processing filters to remove all harmful ultraviolet and infrared, to hydrogen peroxide and a diameter of 20 nm silicon dental equipment dioxide as the main whitening agent, the rapid creation of oxidation-reduction effect. A small tube through the teeth to remove the tooth surface and the deep attachment of pigment to achieve the whitening effect. Not whitening operation for a long time, just 30 minutes. Low-temperature luminescence, completely avoid the operation of the dental nerve stimulation. The main components of whitening agent hydrogen peroxide.

Safety, Blu-ray to complete a full mouth whitening no more than 30 minutes exposure time per tooth less than 1 minute, thus greatly reducing the sensitivity of the teeth or the possibility of overheating.

Efficient, the efficiency of blue light whitening bleaching gel is simple to use 29.5 times, according to the treatment of ergonomically designed handle, teeth after Deciduous dental caries but also to rule each treatment will improve the whiteness of 3-4, 3-5 general whitening effect can be maintained years.

Almost painless, treatment will not hurt, so I do not need anesthesia.

Whitening is a popular in Europe and America are the latest tooth whitening technology, which not only remove the tooth surface pigmentation, and can can reach deep into the tooth bleaching effect.

How long will the teeth grow

Many patients want missing tooth implant restoration, but because of busy work, few people dedicated to do dental implants. So, dental implant take? Will not delay the normal life and go to work? On this issue, we asked the experts.

Dental experts said, the advantages of growing teeth:

1. Retention is good, than the traditional dentures wearing solid, solid.

2. Chewing efficiency has greatly improved over traditional dentures, exactly like real teeth.

3. Implant denture base plate by a small, full fixed implant or no base plate, so beautiful and comfortable, no foreign body sensation, little effect on the pronunciation.

Plant commonly used dental implant system has a surgical implant, and two surgical implant, an implant system abutment of the implant as a whole is directly connected, directly stretching the entrance of the base station; the second base station and the planting of planting body is not a preformed whole, but until the bone around the implant bed with direct healing, and then dental equipment mucoperiosteal incision line abutment connection surgery. There are some differences between the repair time. Once planting is relatively simple columnar easy way, through an operation can be completed, removal of stitches after a temporary prosthesis can be fixed, stable 3 months after implant desirable mode, a few weeks to complete long-lasting repair. After an operation is best not to repair, such as 8 weeks after the basic stability of the implant body can do a temporary repair, do so after six months of permanent prosthesis.

The first implant surgery after 3 to 6 months, five to six months maxillary, mandibular three to four months until the implant-bone interface healing, the implant is capable to support restoration of function, then line two operations, then the base station. In another two weeks, you can start Yellow teeth black teeth whitening methods are there repairing treatment, and periodically reviewed. This planting method because of its effect, is widely used. No matter what kind of implant healing process should be 3 to 6 months, then begin the repair, 6 to 18 months for the bone remodeling process, after entering the steady state, but patients should be regularly reviewed to ensure that there are problems in time.

Safe to do porcelain teeth

In China, about 3 million people to varying degrees, missing teeth, and the installation of a porcelain tooth is dental way many people, it is also installed a large population base porcelain teeth, porcelain teeth do not safety safety will be asked a less frequent, dental experts say that hospitals safe to do porcelain teeth.

Porcelain dentistry full name is "porcelain fused to metal crown." What are the steps to do porcelain teeth? Production of a metal ceramic teeth, need to first be made ​​of metal alloy substrate, and then cover the surface of the alloy powders and high temperature in a vacuum sintering furnace-fused porcelain formed. This made ​​a porcelain tooth, crown porcelain outside not dental equipment a big difference, within the crown are divided into many types, including: nickel-chromium alloys, cobalt-chromium alloy, titanium, gold alloy, and the latest rise of zirconium dioxide for the all-ceramic dental materials. All questions for porcelain teeth are also within the crown around its metal case - the fear of poor health porcelain teeth, porcelain teeth, is worried about the crown of metal materials used on the body. For this reason, in a porcelain dental crown material is the decisive factor in the price. Currently, nickel-chromium alloy for the crown of porcelain teeth in the cheapest price, while being questioned is the safety Expert analysis of the whole process of denture of these porcelain teeth. Survey shows that in the past 20 to 30 years, about 900,000 cases of Ni-Cr alloy porcelain crown may cause allergy in 5 cases (with allergy symptoms, but did not check for allergens and further confirm the diagnosis, after switching to other material, allergy symptoms), not seen lead to kidney failure cases.

Prevention and treatment of bad breath elderly

1. Dental caries in the mouth, or residual crown and root, etc., food debris attached to these lesions, through the role of oral bacteria, food residue after fermentation will produce bad breath. As long as dental caries, or residual crown and root treatment, bad breath will disappear.

2. Periodontal disease in the mouth, especially the formation of chronic periodontal disease blind bags, resulting in a chronic septic overflow and dental equipment odor. At this time the treatment of periodontal disease should be to eliminate the blind bag, in order to eliminate bad breath.

3. Acute inflammation occurs in the mouth, such as acute periodontal abscess, and the third molar pericoronitis go far, are some of the acute inflammatory oral secretions, bad breath can also occur, to cure these diseases, inflammation subsided after the bad breath will disappear .

4. Elderly physiological periodontal tissue atrophy, the gap between the teeth. After eating food debris stuck in the cracks in the teeth, oral bacteria after fermentation the Prevention of dental caries resulting odor. So pay attention to oral hygiene, so sooner or later (before bed) mouthwash after brushing to remove food debris inside the mouth, can prevent the occurrence of bad breath.

5. Digestive diseases. The elderly digestive dysfunction, often indigestion or gastrointestinal reflux disease, gastric retention of food can be produced by the smell exhaled from the mouth, which is an important cause of bad breath produced. As long as the cure for digestive diseases will be eliminated on smell.

What can make teeth stronger?

Preparation of a good first treatment used for filling cavities or holes form, the treatment of dental caries repair key.

Generally speaking, to prepare box-shaped hole-shaped, double-sided hole to form a ladder; remove unnecessary non-base enamel. There should be some retention form. The use of wall, undercut, dove tail, to prepare a trapezoidal shape of its retention. Second is good across the wet, disinfection and drying. Clear the hole of the prepared during the operation due to caries and dental equipment bacteria into the use of rubber or cotton balls, gauze, with the aspirator allows the surgical area to prevent saliva contamination, which will help dry inside, so as to make the filling materials fully contact with teeth, to improve the quality of filling. Finally, the bottom and select the appropriate filling material filling, forming the tooth surface carving, adjust occlusion. Thus, to complete a high quality filling technique. Thus, if the organization fails to remove clean and caries; if the hole is not enough depth preparation, or bottom is too thick, too thin to fill the body; if the hole area of occlusal force or improper retention form preparation, as adjacent occlusal no hole is too narrow dovetail or dovetail too shallow, no proximal trapezoid, shaft angle is too acute myeloid line, box-shaped hole is greater than the cave minors.

If the filling material in the mixing ratio of properly, blood or saliva inside the cave, and other water contact materials, non-drying adhesive surface, can affect the Wrong interpretation of the five oral treatment quality of filling. Therefore, to overcome the above aspects of the adverse factors, the completion of a high-quality filling technique, the teeth can make up more solid.

Recurrence Orthodontics

In the field of oral medicine, dental orthodontics is slowly going through the corrective force to promote the teeth or jaw dislocation through a complex series of biological machinery - sports, beauty and function to achieve good results. However, due shortly after the teeth have moved slightly loose, and there is a tendency to return to its original position, if not do a good job-related measures can easily lead to dental orthodontic relapse. So now the more common causes of recurrence Orthodontics What is it?

     

The relatively common dental orthodontic relapse reasons: ① periodontal tissue, bone joints, and joint reconstruction was not completed. ② new bite imbalance. ③ new muscle imbalance. ④ over the limit of the correction, due to the teeth, jaw and muscle did not result in co-ordination and balance, easily lead to relapse. ⑤ growth process is affected by the type dental equipment of growth, prone to relapse. ⑥ oral bad habits is not completely correct. Bad habits again lead to a mistake (occlusion) of recurrence. ⑦ adult tissue reaction decreased, reducing the cellular components of periodontal tissue, tissue remodeling slow, easy to relapse, in addition to a genetic tendency to relapse more likely.

     

Cause dental orthodontic relapse are many reasons why, in order to prevent recurrence of orthodontic tooth phenomenon, it is recommended that consumers can make the relevant measures to prevent their teeth orthodontic efforts in vain.
