Abstract
[...]in order to identify these shortcomings of retention, long-term data collected from both literature and clinical experience can identify the better means of retention for maxillofacial prostheses. In order to know the best possible means of retention systems for maxillofacial prostheses, the implant-supported prostheses, adhesivesupported, bar-clip and magnetic systems of anchorage should be evaluated both in terms of clinical experience and long-term outcome. 2.MATERIALS AND METHODS Research strategy and study selection The published literature was searched using Science Direct, Wiley Online Electronic data base, PubMed and Cochrane Library. Each item received equal weighing (Y = 1 point, N = 0 points, N/A= not applicable = 0.5 points), the overall score being used as a quality index for the respective study. 4.DISCUSSION A total of 12 studies published within the last 30 years and related to implants, adhesive, barclip and magnet, were included in the analysis. 3 studies were devoted to bar-clip and magnetic retention, 1 to adhesive-retention, 1 to implant and adhesive retention and 7 to implant anchorage. The implant survival rate recorded was 93.3%, the results of the study considering both the nonoirradiated and irradiated group of patients, in contrast to Arcuri et al. studies.
