Dental implants made from binary titanium-zirconium (TiZr) alloys have shown\r\npromise as a high strength, yet biocompatible alternative to pure titanium, particularly for\r\napplications requiring small diameter implants. The aim of this review is to summarize\r\nexisting literature reporting on the use of binary TiZr alloys for endosseous dental implant\r\napplications as tested in vitro, in animals and clinically. And furthermore to show that TiZr\r\nis ââ?¬Å?at least as good asââ?¬Â pure titanium in terms of biocompatibility and osseointergration.\r\nFrom the twelve papers that met the inclusion criteria, the current literature confirms that\r\nTiZr alloys produce small diameter implants with a strength up to 40% higher than\r\nconventional, cold-worked, grade IV titanium implants, and with a corrosion resistance and\r\nbiocompatibility that is at least as good as pure titanium. The surface structure of TiZr is\r\ncompatible with established surface treatments proven to aid in the osseointegration of\r\ntitanium implants. Furthermore, binary TiZr alloys have been shown to achieve good\r\nosseointegration and high success rates both in animal and in clinical studies.
