Marginal Adaptation in Fixed Prosthetic Restorations

Marginal fit plays an important role for a dental restoration. The degradation of cement in oral cavity can result in loss of marginal seal, retention of plague, development of secondary dental caries and periodontal diseases.Increasing marginal discrepancy results in progressive cement dissolution. The aim of this study was to discuss the factors effecting the marginal adaptation and informing about the methods which have been used to evaluate the marjinal adaptation between tooth structure and restorative materials
