ABSTRACT

The purpose of the present study was evaluate the biological compatibility of materials used to manufacture prostheticappliances. A heat-polymerized colorless resin and one visible light-cured denture base material were tested by the implantation of probe discs, in the dorsal connective tissue of 12 Wistar rats. The animals were sacrificed at 7, 14, 21 and 28 days after implantation. The specimens were prepared for light microscopy observation. It was noted that either after light microscopy observations, both resins demonstrated a good level of biocompatibility within the connective tissue of the dorsum of the animals studied.


O objetivo deste trabalho foi avaliar a compatibilidade de biológica de materiais usados na confecção de aparelhosprotéticos. Foram testadas uma resina incolor ativada termicamente e uma resina rosa ativada por luz visível. Discosdestas resinas foram implantados no tecido conjuntivo do dorso de 12 ratos Wistar. Os animais foram sacrificados em 7,14, 21 e 28 dias após a implantação. Os cortes foram preparados para observação em microscopia de luz. Observou-seque as duas resinas demonstraram bom nível de compatibilidade no tecido conjuntivo.
