The use of an appropriate implant biomaterial significantly determines the success of implants. The biologic environment where implants are placed does not necessarily accept any material. Therefore, biologic performance can be optimized by selecting implants that reduce negative biologic response while at the same time functioning adequately. Besides, clinicians should be knowledgeable of different biomaterials used for purposes of dental implants. The purpose of this paper is to provide an overview on the issue of dental implants. Some of the implants discussed in the paper include titanium and zirconia implants. Furthermore, the paper discusses how physical properties of the materials influence the treatment outcome.
