Dental implants have become increasingly common for the management of tooth loss. Meanwhile, several implants still fail as a permanent solution despite the intense research on this subject. Failures on these implants are usually related to the loosening of the implant, causing inflammations, infections, decrease in bone density and release of toxic agents to the human body. On the bases of these problems are phenomena like corrosion and wear of the material composing the dental implant. In this way, it becomes necessary to better understand the mechanisms of corrosion and wear behind dental implants. The present work will increase the knowledge on the tribocorrosion mechanisms of titanium as well it will study the influence of a new surface treatment by anodization. Experimental tests will resemble the conditions presented on the oral cavity and will subject Etched and Anodized titanium samples, as well biomodified titanium samples, to tribocorrosion evaluations. The effects of the normal load and velocity of rotation on the process of tribocorrosion will be addressed and the effect of the biological material (osteoblastic cells MG63) on the degradation and corrosion behavior will be compared with the non cultivated samples. In addition, prior to cellular culture, some samples will be subjected to tribocorrosion tests to determine if the changes of the superficial properties present more affinity for osteoblast growth.

520 $a Dental implants have become increasingly common for the management of tooth loss. Meanwhile, several implants still fail as a permanent solution despite the intense research on this subject. Failures on these implants are usually related to the loosening of the implant, causing inflammations, infections, decrease in bone density and release of toxic agents to the human body. On the bases of these problems are phenomena like corrosion and wear of the material composing the dental implant. In this way, it becomes necessary to better understand the mechanisms of corrosion and wear behind dental implants. The present work will increase the knowledge on the tribocorrosion mechanisms of titanium as well it will study the influence of a new surface treatment by anodization.

520 $a Os implantes dentarios tornaram-se cada vez mais comuns no tratamento da perda de dentes. No entanto, diversos implantes continuam a falhar como uma solucao permanente independentemente da intensa investigacao existente na area. As falhas nestes implantes sao, normalmente, relacionadas com a perda de fixacao do implante que conduz a inflamacoes, infeccoes, diminuicao da densidade ossea e libertacao de agentes toxicos para o organismo. Na base destes problemas estao fenomenos como corrosao e desgaste do material que compoem o implante dentario. Deste modo, torna-se necessario compreender melhor os mecanismos de corrosao e desgaste por detras dos implantes dentarios. O presente trabalho vai permitir aumentar o conhecimento dos mecanismos de tribocorrosao do titanio, assim como estudar a influencia de um novo tratamento de superficie realizado por anodizacao. Os testes experimentais vao simular as condicoes na cavidade oral e irao submeter amostras de titanio Etched e Anodizadas, assim como amostras Biomodificadas, a avaliacao de tribocorrosao. O efeito da forca normal e velocidade de rotacao no processo de tribocorrosao serao abordados e o efeito da presenca de material biologico (celulas osteoblasticas MG63) na degradacao e na corrosao do material sera comparado com as amostras nao sujeitas a cultura. Alem disso, antes da cultura celular, algumas amostras serao sujeitas a testes de tribocorrosao de modo a determinar se a alteracao da superficie apresenta maior afinidade para o crescimento de osteoblastos.
