[Aspects of the biological behaviour of the rubber RS 330T-RTV silicon material].
The resorption and atrophy of the prosthodontic prosthetic field via the mobile restorations made of flexible acrylate, constitutes a controversial problem in the specialty literature, determining the interest of the clinicians with regard to the counterattacking or improving this process inherent to the indentation evolution. The study aims at analyzing the biological behavior of the silicon type RUBBER RS 330T-RTV, a material often used in the creation of the maxilo-facial prosthetics. The method proposed by us has the object of lining the prosthetics made of flexible acrylic type Valplast with this type of silicon. The practical aspects have been forwarded by the biocompatibility studies, applied to the silicon test-tubes, made in the dental technique laboratory, or to the hypodermic implants at the rodent laboratory animals. At the macroscopic examination it can be observed that the silicon fragment maintains it's almost parallelepiped form. The microscopic exam reveals structural mending phenomena, initially mainly the lymphohistocyte cells, and then mainly the fibrous cells. Biocompatibility aspects certifiable at the RUBBER RS 330T-RTV silicon material are fully according to the biocompatibility notions afferent to the silicon materials. Key words:
