Implants are the latest trends in dentistry and the long term clinical success of implants depends on various factors. One of the important factors among these is the appropriate selection of the implant biomaterial. No material is completely accepted by the biologic environment therefore to optimize biologic performance, implants should be selected to minimize the negative biologic response while ensuring adequate function. Every clinician should always gain a thorough knowledge about the different biomaterials used for the dental implants and judicious selection should be made before a clinical trial in great haste. This book makes an effort to summarize various materials which were used in the past and are now obsolete as well as the latest materials used as an implant biomaterial
