The osseointegration of Ti-Zr implants – a new perspective in oral implantology

Abstract

Pure titanium represents one the most widespread biomaterials used for dental implants; on the other hand titanium alloyed with aluminum and vanadium (Ti-6Al-4V) is mostly used in the technological process of fabrication of dental prosthetic restorations. Because pure titanium offers low resistance to loading and Ti-6Al-4V may lead to a gradual release in metallic ions with consecutive immunologic repercussions, in this study will be discussed: the technological procedures of obtaining Ti-Zr alloy, the microstructural modifications corroborated with the applied thermal regimen and the biocompatibility of Ti-Zr in relation with human osteoblasts (G292).
