[Technology and progress in dental prosthodontics and dental materials].

This publication describes and scrutinizes new technologies in the field of prosthodontics including functional analysis and therapy, fixed and combined fixed/removable prosthetics, and implant supported/relained dentures. In spite of all new developments with regard to digitized imaging (CT;NMR) of the TMJ as well as in spite of all electronic devices for recording the mandibular movement, new therapies have not been established. The clinical examination is still of primary importance. In fixed prosthetics the different ceramic and glass/ceramic systems represent aesthetic and hygienic alternatives to single, porcelain-fused-to-metal restorations. Titanium exhibiting good biocompatibility, sufficient strength, and a low price gradually becomes of greater importance. In combined fixed/removable prosthetics the various metal-resinbonding-systems as well as the spark erosion technique--the latter being used for precision attachment work utilizing base metal alloys--can be described as major achievements in our profession. In dental implantology, a great variety of different implant systems have been introduced to the market. Based on the clinical experience of the last decade, the following can be stated: The implantological prosthetic treatment of the lower jaw using two implants and a clip-to-bar retained denture shows the best cost-risque-benefit ratio among all possible indications. In the future, more research should be directed to the prosthetic suprastructures and their influence on the long lasting success of implant supported retained constructions.
