![]() ![]() The other main source of implant failure is the mechanical breakdown of any dental implant components that manifest as damage and/or fracture of the implant body, implant abutment, and the implant screw (Goodacre et al. ![]() The biological failure can generally refer to poor osseointegration process, whether in early or late stages post implantation, due to several factors, including surgical trauma, infections, and inflammations like peri-implantitis. The sources of implant failure are basically categorised as biological and mechanical. ![]() The stress distribution at the bone –implant interface is considered one of the key elements in determining dental implant stability. Despite the high clinical success rate, dental implants are still receiving attention from many researchers investigating its different aspects. The success is due in large part to osseointegration, a term coined by Brenmark in 1952.Mechanical features of the implant, such as mechanical stability, tensile and compressive strength, and stress distribution at the implant-bone interface, all play a role in its long-term stability. Dental implantation has been used to restore lost teeth effectively for many years all around the world. ![]()
