Complications and Maintenance in Dental Impant Introduction Complications may occur in both the surgical and prosthodontic phases of implant therapy. It is essential to warn patients of the possibility of surgical and postoperative problems. Introduction Failure of osseointegration is relatively rare in well-planned cases, with most failures occurring soon after surgical placement or before loading. Introduction Complications in most cases are avoidable by careful attention to diagnosis, treatment planning and good surgical and prosthodontic planning, and by following established protocols of individual implant systems. Surgical complications The more common, relatively minor complications following surgery include swelling, bruising and discomfort. All patients should be warned of these complications and the anticipated extent of them before surgery is undertaken. Surgical complications As with all minor surgical procedures, surgical complications can be minimised by adequate aneasthesia, gentle surgical manipulation of both hard and soft tissues, pre- and postoperative analgesia, and careful postoperative wound management, including the use of pressure and ice packs to reduce swelling. Surgical complications Haemorrhage may occur at the time of surgery if there is excessive trauma to soft tissue or damage to aberrant vessels within the bony cortex. Surgical complications Failure to establish good primary stability at the time of implant placement may result in early failure. Surgical complications Incorrect positioning of implants at the time of surgery, as a consequence of poor planning or lack of necessary skills, knowledge and understanding may result in considerable difficulties during the restorative phase of treatment. Surgical complications It is essential to use surgical guides and templates if positioning problems are to be minimised. Postoperative Pain Mild postoperative pain is to be expected. It sh
