The choice of the type of prosthetics is the work of the dentist, not the patient. A suitable type of dental prosthesis is chosen on the basis of many factors: the patient's health and age, the degree of dental preservation, individual characteristics, material possibilities and lifestyle. But one thing is certain - modern techniques of denture can solve any problem.
Fixed prosthetics of teeth
Prosthetics with crowns. Crowns are prostheses which are established on the rest of a tooth, as a cap. They are made of a wide variety of materials.
-Metallic . This kind of crowns is gradually becoming a thing of the past and is now considered obsolete. Few people want to sparkle with each smile. However, sometimes they are still done. We can not say that their performance is bad - crowns made of gold, platinum and other precious metals are very durable and last long (up to 20 years), they are not very expensive, they wear out slowly. But unattractiveness and inaccurate landing on the tooth cross out these virtues.
-Metal ceramic. A ceramic coating imitating tooth enamel is applied to the metal substrate. Such crowns are very popular - they are strong, indistinguishable from real teeth, serve up to 15 years and are relatively inexpensive - at least, the "price-quality" ratio is good. However, there are also disadvantages - the tooth under such a crown is ground and repulped, and heavy-duty ceramics can injure neighboring teeth if not properly installed. Sometimes, if the work was performed poorly, a strip of the metal base of the crown may be visible at the edge of the gum.
-Ceramic. Made entirely of ceramic, without a metal base. These crowns allow the most accurate imitation of natural enamel, up to the texture and transparency. Therefore, such crowns are used for prosthetics of the front teeth. They do not wear out for a long time and do not change color. But ceramics, for all its strength, is fragile - it withstands pressure, but not a sharp force, so chipping is not ruled out. The high cost of such prosthetics is also a disadvantage.
Of zirconium dioxide. The variety of ceramic crowns for all its positive properties is very similar to the previous species. But the main difference is the most modern, aesthetic and reliable material. Suitable for any type of prosthetics. Serves from 15 to 20 years.
Of aluminum oxide. It does not look much like the material from which, for example, the dishes are made. This is a white translucent mass. Such crowns are strong, look very aesthetically. This is the most expensive kind of crowns.
If several adjacent teeth are lost, it makes sense to put a bridge. A bridge is a design consisting of several crowns connected together.
Bridges are of different types:
-Based on your own teeth. These bridges are attached to pre-prepared own teeth.
-Based on implants. If the teeth are lost, the doctor will install implants in their place, on which the bridge will be kept. These implants are purely functional (they are a metal pin), so do not confuse them with aesthetic implants.
-Adhesive bridge structure. The bridge is attached with a thin plate, glued to the supporting tooth. This method does not require the turning of neighboring teeth, however, the design fixed in this way does not withstand heavy loads.
