Abstract(s)
A reabilitação oral consiste num dos maiores desafios da Medicina Dentária atual, uma vez que persiste na busca de um material que possua dois dos seus maiores pilares: a função e a estética. O titânio e as suas ligas têm sido o material substituto e reabilitador de eleição. Todavia, existem cada vez mais fenómenos no seu uso e manuseamento que sabotam a durabilidade deste material nos tratamentos de reabilitação. Nomeadamente, falhas no que diz respeito à corrosão e desgaste, resultando num fenómeno chamado tribocorrosão, que surge através da conjugação destes elementos.
O objetivo deste trabalho é desenvolver os fenómenos de corrosão e desgaste, assim como as principais consequências do comportamento tribocorrosivo no meio oral e como este pode influenciar no insucesso da reabilitação com implantes
Conclui-se que, nos dias de hoje, são necessários mais estudos “in vivo” para encontrar o material perfeito para a reabilitação oral.
Oral rehabilitation is one of the greatest challenges of current dental medicine, since it persists in the search for a material that has two of its major pillars: function and aesthetics. Titanium and its alloys have been the substitute and rehabilitating material of choice. However, there are more and more phenomena in its use and handling that sabotage the durability of this material in rehabilitation treatments. In particular, failures with regard to corrosion and wear, resulting in a phenomenon called tribocorrosion, which arises through the conjugation of these elements. The objective of this work is to develop the corrosion and wear phenomena, as well as the main consequences of tribocorrosive behavior in the oral environment and how this may influence the failure of rehabilitation with implants. We conclude that, today, more in vivo studies are needed to find the perfect material for oral rehabilitation.
