A Review of the Major Prosthetic Factors Influencing the Prognosis of Implant Prosthodontics

Background: The treatment plan of prosthetic restorations supported by dental implants requires comprehensive scientific knowledge to deliver prostheses with good prognosis, even before the implant insertion. This review aims analyze main determinants prognosis implant-supported prostheses. Methods: A literature was conducted a PICO (Patient Intervention Comparison Outcomes) question: “For partially or complete edentulous subjects treated prostheses, which factors could affect clinical outcomes?”. search performed electronically in PubMed (MEDLINE), Scopus and Cochrane Library following equation [PROGNOS * OR RISK] FACTOR IMPLANT DENTAL, hand relevant journals throughout selected papers. Results: revision carried out based on 50 papers focused several prosthodontics-related risk that were grouped as follows: implant-connection, loading protocol, transmucosal abutments, fit, provisionalization, type retention, impression technique, fabrication occlusion. More than half studies systematic reviews (30%), meta-analysis (16%), prospective evaluations prosthesis various kinds events (18%). However, narrative (14%) vitro/animal (16%) also found. Conclusions: current provides insufficient evidence for most investigated topics. accumulated data, it seems reasonable defend best approach is use morse taper recorded means rigidly splinted copings through pick-up screwed milled occlusally adjusted minimize functional overloading.
