Implant Failures - A Review

A dental implant is a prosthetic device made of an alloplastic material implanted into the oral tissues beneath the mucosal and periosteal layer and within the bone to provide retention and support for a fixed or removable dental prosthesis. Implant is the best way to prevent bone loss and edentulism with better replacement options. From the view of prosthodontist it is important to identify the factors that consociate with the failure of the implant. Various studies reveal that only 2mm of bone loss occur per year in case of replacement of the tooth by implants. Hence this review is intended to focus on reducing the failure of implants by entailing occlusal load, crown height and abutment retention loss.
