This is used in the following cases:
Crowns are used for severely damaged teeth restoring the normal form and function of the tooth, as it protects the tooth against fracture and subsequent extraction. There are:
In the absence of one or more teeth, or any tooth restoration of the tooth row, occurs via implants, bridges, partial or complete denture.
The implants are made of biocompatible material and are placed directly in the jaw. This avoids grinding of healthy teeth and atrophy (melting) of the bone, which leads to a cosmetic problem when the defect is in the visible part of the smile (for more information - "surgery").
Bridges are non-removable shell construction in which two or more teeth are thinned as missing teeth are replaced with artificial ones. Most of the time the artificial teeth are fixed to two supporting teeth between which bridge body is placed. Depending on the material used for the construction, bridges and crowns can be:
Partial or complete dentures are used when treatment with implants or bridges is not possible. The Partial denture is a structure which is fastened for the remaining teeth by hooks or other mechanisms and after eating it is removed and cleaned. A plastic basis is most frequently used for a base on which plastic or ceramic teeth are positioned. Complete prostheses are used in the case of total edentulism.
