Histological analysis of the osseointegration of Ti-30Ta dental implants after surface treatment
(2013-02-28)
Metallic biomaterials are used to reinforce or to restore the form and function of hard tissues. Implants and prosthesis are used to replace shoulders, knees, hips and teeth. When these materials are inserted in bone several ...
Estudo microestrutural e resistência à corrosão de uma liga de Au soldada a laser, empregada em prótese sobre implantes
(Editora Unesp, 2002-01-01)
Investigou-se o comportamento de juntas soldadas de uma liga a base de ouro utilizada na confecção de próteses odontológicas sobre implantes antes e após ser submetida ao processo de soldagem a laser. Constatou-se que houve ...
Microestrutura e resistência à corrosão do Ti c.p. soldado a laser utilizando em prótese sobre implantes
(Editora Unesp, 1999-01-01)
Foram realizados estudos para avaliar a microestrutura, a dureza e a resistência à corrosão do titânio comercialmente puro-Ti c.p. soldado por laser e utilizado na confecção de prótese sobre implantes. Verificou-se que na ...
