A dental prosthesis is an intraoral prosthesis used to restore (reconstruct) intraoral defects such as missing teeth, missing parts of teeth, and missing soft or hard structures of the jaw and palate.
A dental prosthesis is an intraoral prosthesis used to restore (reconstruct) intraoral defects such as missing teeth, missing parts of teeth, and missing soft or hard structures of the jaw and palate. Prosthodontics is the dental specialty that focuses on dental prostheses. Such prostheses are used to rehabilitate mastication (chewing), improve aesthetics, and aid speech. A dental prosthesis may be held in place by connecting to teeth or dental implants, by suction, or by being held passively by surrounding muscles. Like other types of prostheses, they can either be fixed permanently or removable; fixed prosthodontics and removable dentures are made in many variations. Permanently fixed dental prostheses use dental adhesive or screws, to attach to teeth or dental implants. Removal prostheses may use friction against parallel hard surfaces and undercuts of adjacent teeth or dental implants, suction using the mucous retention (without or without aid from denture adhesives), and by exploiting the surrounding muscles and anatomical contours of the jaw to passively hold in place.
In the case of loss of a certain amount of hard tissue, reconstruction may be conservative if there applies the usage of fillings. For greater precision and better design, fillings can be made in laboratory. Today’s modern technology of computer drafting and machining of metal – free ceramic restorations offer optimum accuracy which is the basic prerequisite for the success of treatment that eliminates all the disadvantages of a conservative resolution of the composite “white” fillings.
Depending on whether they cover part of the chewing surfaces, the greater part or the entire surface distinguish inlay, onlay and overlay.
