Revisión sistemática sobre adaptación marginal con sistema CAD/CAM.

Abstract

Introduction: the cad / CAM ceramic dental systems, are a good alternative at the time of speed when delivering our restoration, working with a material such as lithium disilicate popular for aesthetic restorations offering us an adequate color, surface texture, translucency, at the time of marginal adaptation it will be essential to make a good preparation since this will influence the longevity and subsistence of both our stump and the crown. Objective: Investigate the level of marginal adaptation, to find out the longevity in future care of the restoration. Materials and methods: A systematic review of an analytical, descriptive, crosssectional and retrospective nature was carried out; using metasearchers: Pubmed, Google Scholar, Web of Science, Scielo and Cochrane Library, of review of 700 articles and by criteria of inclusion and exclusion, 63 related articles were studied. Analysis and discussion of results: The research on the CAD CAM system with lithium disilicate ceramics presents an acceptable adjustment of 50 to 100 μm, presenting a 10-year life rate of 87.9% and a low fatigue to damage, with a capacity of 1360N to withstand masticatory loads. Conclusion: The scientific evidence refers that to achieve a satisfactory treatment in our lithium disilicate ceramics with CAD / CAM system, we must take into account all the important accepts that will lead us to a longevity of our restoration, the good marginal and internal adjustment, will minimize the discrepancy and increase the fracture resistance.
