ABSTRACT
One can loose a tooth due to dental diseases and conditions like: cavities and periodontal. The loss of one or more dental pieces contributes to a deficit in the mastication efficacy, with functionally and organic consequences. This is why patients prefer to replace dental pieces for dental prosthesis. Dental ontologists use a provisional prosthesis. The main purpose of using the provisional prosthesis is to restore the oral integrity of the patient until a final design of the prosthesis is elaborated. Although in some cases the maintenance of the prosthesis is secondary, this process is very important for the complete restoration of the set of teeth (Figs. 1 and 2). Hygienic precautions, correct use, maintenance and the conservation of the dental is a very important topic among patients, because cavities and other premalignant injuries can be avoided with use of established methods of maintenance. This chapter discusses biomechanics of dental prostheses and biomaterials for these prostheses.
