Occlusion in implantology: sytematic review

Occlusion is an important key in the success of the prosthetic reconstructions. Different principles of occlusion can be used, but there is no evidence that a particular concept is superior to others. The aim of this review is to evaluate what is the best occlusal concept for implant prosthesis? And what are the occluso-prosthetic factors that determine the success of an implant treatment?. An electronic search of the PubMed database was conducted, questioning the scientific literature dealing with this topic for a period of ten years from 2005 to 2015.The MeSH words used were: Occlusion, Implant, Prosthesis. Two independent reviewers achieved screening and data abstraction. Thus the final selection yielded 33 articles. Randomized clinical trials of implant prosthesis occlusion, which are present in the current literature, are very limited. So in order to refine the object of the study we selected 5 systematic reviews using the Mesh words previously mentioned, and carried out a complementary hand-search, covering the same study period, using the following Mesh words: "occlusion , implant "," implant prosthesis, occlusion ". The search yielded 22 valid items. There is a large heterogeneity of parameters and protocols. Much of the information available is taken from occlusal concepts for non-implant dentures. Occlusion discussions are based on personal experience rather than scientific studies. Occlusion has been and will always be an important variable in the success or failure of most prosthetic reconstructions. There is no evidence-based evidence regarding the concepts of occlusion in supra-implant prosthesis. Further studies in this area are needed to clarify the relationship between occlusion and implant success.
