Implants are commonly used in dental practice and
implant-supported restoration offers a predictable
treatment for tooth replacement. However there are
many risk factors of implant that is generally divided
into patient-related factors (general health status,
smoking habits, quantity and quality of bone, oral
hygiene maintenance), implant characteristics
(dimensions, coating, loading), implant location, and
clinician experience1). Factors such as the surgical
technique and the type of graft material or implant
can affect implant survival2) and then the quality of
implant surfaces, graft materials and surgical
techniques has been developed to make high survival
rates of implants.
