Resumo: The aim of this review was to update the concepts regarding the preparation of the surfaces of titanium implants, focusing on SLA (sandblasted and acid etched implants). Texture was the most remarkable isolated feature, regarded as an osseointegration promoter. In a comprehensive review of the effects of implant surface topography on cell behavior, one can verify that there is bone apposition onto the implant surface regardless of its characteristics: polished or rough, made of titanium. Studies indicate that microstructuring by sandblasting and acid etching (SLA) enhances the osteogenic properties of titanium. Roughness is mandatory for bone apposition. It has been shown that roughness may play an important role in the percentage of bone apposition as well as in the velocity of apposition. In this review, a quite promising type of surface called SLA is pointed out, showing that either roughness or acid conditioning of the surfaces can significantly improve shear strength. Besides optimizing the procedure, these surface characteristics may, eventually, allow for an earlier loading of the implant and extend the indications for implants in low-density alveolar bone and in regenerated bone. UNITERMS: titanium; dental implant; texture of surface.

UNITERMS: titanium; dental implant; texture of surface.Dentre as várias características dos implantes a topografia da superfície é reconhecida como fator capaz de alterar a resposta das células dos tecidos adjacentes modificando a migração, inserção, proliferação e síntese de colágeno no local, determinando assim o tipo de tecido que será obtido na interface osso-implante e sua integração. Graças aos diferentes tipos de tratamentos tornou-se possível obter várias formas de caracterização da superfície facilitando a compreensão dos padrões de formação óssea, comportamento das células e até mesmo prever o tipo cicatricial que será obtido a partir da conformação dos tecidos adjacentes às superfícies dos implantes. Superfície de titânio com a rugosidade e microestrutura complexa aumenta a osseointegração no contato osso e implante, eleva a força de torque de remoção in vivo e a diferenciação in vitro dos osteoblastos induzidos pela função de rugosidade e topografia na osseointegração. Em superfícies de implantes tratadas com plasma de titânio (TPS), jateadas com areia e tratadas com ácido (SLA) os resultados demonstraram que tanto a rugosidade como o tratamento químico das superfícies pode influenciar bastante a força superficial de cisalhamento (resistência oferecida à remoção). Estas características da superfície do titânio, além de otimizar o procedimento, podem ainda, por exemplo, permitir a colocação dos implantes em função mais precocemente e ampliar a gama de aplicações possíveis para osso alveolar de densidade inferior ou favorecer sua aplicação em osso regenerado.
