Overdentures supported by implants are a comparatively new arrival in the prosthodontic scene. It is found to have increasing application in prosthodontics, which may be a reflection on population trends and the demand for better treatment. Overdenture treatment is a notion which precludes the inevitability of "floating plastic" in edentulous mouths. It has always offered a sensible and prudent appeal for dental practitioners, and numerous patients have benefited from this prescription. The implant-retained overdenture is a treatment option for edentulous patients in the following situations: poorly retained and unstable mandibular dentures, poor bone quality or insufficient available for bone to accommodate four or more implants, as the original Branemark protocol suggests.The main aim of this new upcoming treatment option was to provide support, stability and retention. Several prosthodontists around the world chose to develop the notion of implant supported overdentures. As a result a new standard of prosthodontic services for the edentulous patients has emerged.
