The prosthetic dentistry can be divided in two main groups: the fixed prosthesis (crown and bridge) and the removable prosthesis (total or partial dentures).
The crowns completely cap the tooth and are used when a large amount of dental tissue is lost. It could be simple or associated with a post and core to increase its retention. This treatment is long, less economical than a simple filling but has a very good esthetical and prognosis outcome. The true inconvenient of this treatment is the sacrifice of dental tissues to create enough space for the prosthetic piece.
A bridge allows the replacement of a single or multiple missing teeth by using the adjacent tooth. These two anchoring teeth are called abutment teeth – and a false tooth/teeth in between. The abutment teeth are prepared like a single crown. The prosthesis can be made from gold, alloys, porcelain, or a combination of these materials.
Fixed prosthesis on implant :
The crown and bridge can be sealed or screwed on the implants. The main indication is the replacement of missing single tooth, but can replace several ones or a total arch.
The patients can remove and reinsert a removable prosthesis when required. It usually replaces multiple missing teeth. It lays on remaining teeth/gum/implant. Different types are proposed
Metallic removable denture are made of a metallic base laying on the teeth and recovered by a pink resin supporting the prosthetic teeth.
Temporary resin partial dentures, they are only made of resin material and used for temporary replacement of single or multiple teeth.
Dentures, also known as false teeth, are prosthetic devices constructed to replace a total arch. Conventional dentures are removable, however there are many different denture designs, some which rely on bonding or clasping onto teeth or dental implants
