Adaptación marginal de cofias metálicas fabricadas con dos sistemas : CAD CAM y técnica convencional. Revisión sistemática.

Abstract

Marginal adaptation is important to ensure the success and longevity of the restoration; The metallic Cr-C alloy coping is the most used in the world of dentistry for restorations and its fit can be affected by the type of manufacture of the same. Objective: to compare the marginal adaptation of the two types of manufacturing, CAD CAM and conventional technique. Materials and Methods qualitative approach study with a descriptive type of research and a non-experimental research design; reviewing 30 articles between 2006 and 2020. The search source was the Meta search engines Pubmed, Cochrane and Elsevier. Results The marginal adaptation provided by the different systems and methods was analyzed, thus obtaining values greater than 120 μm in the conventional technique and reaching values less than 50 μm through the use of the CAD CAM system. Conclusion it was concluded that the adaptation of the copings using the two systems provided clinically acceptable values for restoration.
