NEW MATERIALS USED IN CREATING BASES OF POLYMER PROSTHESIS

Even in times when oral implantology (increasingly precise and accepted) is consolidated its position within the prosthetic restorations, materials for prostheses bases remained however a component which cannot be waived. Their comparison provides an overview about all variations of modern materials and also about their role in a system . Topical material in case of mobile prostheses is dominated by polymethilmethacrylate (PMMA). Most of these materials are thermo-polymerizable . An optimal polymerization is very important because it proved that the residual monomer has toxic effects on the tissues with which it comes into contact . Increased residual monomer content can be considered definitely a disadvantage in terms of allergic reactions that may cause patients. All materials accepted today to restore must meet ISO 1567-2000, yet still cannot exclude a certain risk. The monocomponent materials are available, which can be processed by a process of thermoplastic injection, so that the residual monomer disappears. The decision to use should be taken into account to the economic factor . A system that at first time may seem expensive, offers a good alternative in their own environment, contribute to a good restoration and quality in the near future. Over the period we have indexed the most important documentary material from the literature consulted, and finally to have an overview of the progress in this area. We considered useful to present the collected data that may be out of reach of practitioners as a true handbook of materials.
