Prostheses of this group are firmly fixed on the teeth by various dental cements. Fixed prostheses are divided into:
- adhesive prostheses;
Tabs are made in the laboratory by individual snapshots, and, in fact, they are a strong seal, made of ceramic, compomer (filling materials that produce fluorine) and other materials. They are used in significant destruction of the tooth when it is impossible to simulate the quality seal in the patient's mouth.
Veneers — ceramic inlays on the front teeth — can change the shape, color of teeth, correct the defect of their situation and achieve dazzling "Hollywood" smile. A similar type of prosthesis solves the aesthetic problem and requires a doctor's considerable skills and sense of taste. Veneer is a thin, usually ceramic, flake very tight fitting to the tooth. For its production removes a thin layer of the tooth and a highly accurate impression of the prepared tooth. After production of the laboratory ceramic enamel lining is firmly attached to the tooth.
When a tooth is very badly damaged or the color has changed and darkened
In some clinics, progressive approaches to prosthetic crowns a little different. There's no call for "depulpirovat" tooth, as when it is processed by a special preparation method that can accurately remove only as much tissue to be able to make a crown. In addition, the crown fits so precisely to the tooth that the boundary is smooth, it has a beneficial effect on the functioning of the term of the crown and the state of the gums.
In the absence of one or several teeth need adequate exchange. For this purpose Bridges. Bridge prosthesis— This non-removable structure, which relies on a few teeth, and is intended to replace a missing tooth or group of teeth. As a support bridge most commonly used artificial crown.
In order not to grind the teeth for crowns alive to hold the prosthesis can be appliedadhesive bridge. Using high-tech materials, made a "bridge", which is firmly bonded to the adjacent teeth. In this case, the teeth remain intact, however serve a "bridge" long, usually no more than 5 years.
Dentures on implants
Installation is now practiced in place of the missing tooth artificial root — an implant that acts itself and allows you to operate the retaining his bones. Crowns on implants are much longer and are the most physiological view of prosthetics.
Root form implant allows you to immediately after the removal of the "sick" of the tooth to install it into the opening in the bone. This technique allows you to "cheat" in nature — an artificial implant begins to function as your own tooth. Even if tooth has been removed for a long time is not an obstacle for the use of this method, which in scientific language is called "immediate functional loading."
In addition to individual implant crowns and bridges installed. The only difference from the "bridge" installed on the machined teeth is necessary otutstvie
