Abstract(s)
Em Medicina Dentária a perda de dentes é muito comum e pode ocorrer em consequência de doenças ou traumas. O uso de implantes dentários para substituir dentes perdidos tem uma longa história. No passado, a única forma de substituir dentes que eram perdidos era colocar uma prótese removível. No entanto, atualmente, são usados implantes dentários para esta finalidade e ao longo dos tempos os implantes dentários têm vindo a ser melhorados como resultado dos avanços tecnológicos e científicos. No passado foram utilizados materiais como chumbo, aço inoxidável e ouro para a produção de implantes dentários. Atualmente, o foco está no uso de Roxolid, implantes de titânio e zircónia modificados na superfície, que possuem excelentes características estéticas e funcionais, mas estas soluções proporcionam tempos de osseointegração muito longos, cerca de 6 meses.
A existência de superfícies diferentes pode reduzir os tempos de osseointegração e o aparecimento de peri-implantite, bem como aumentar a biocompatibilidade e a resistência à biocorrosão.
O objetivo deste trabalho é comparar o titânio comercial com as ligas de titânio-zircónia avaliando as diferenças entre os materiais e os métodos de tratamento de superfície de ambos, destacando as vantagens e desvantagens.
In dentistry, tooth loss is very common and can occur as a result of disease or trauma. The use of dental implants to replace missing teeth has a long history. In the past, the only way to replace missing teeth was to put in a removable denture. However, nowadays, dental implants are used for this purpose and over time dental implants have been improved as a result of technological and scientific advances. In the past, materials such as lead, stainless steel and gold were used for the production of dental implants. Currently, the focus is on the use of Roxolid, surface-modified titanium and zirconia implants, which have excellent aesthetic and functional characteristics, but these solutions provide very long osseointegration times, around 6 months. The existence of different surfaces can reduce osseointegration times and the appearance of peri-implantitis, as well as increase biocompatibility and resistance to biocorrosion. The aim of this work is to compare commercial titanium with titanium-zirconia alloys, evaluating the differences between the materials and the surface treatment methods of both, highlighting the advantages and disadvantages.
