Marginal adaptation and mechanical strength of endocrowns with different materials and tooth prepration design: a review

The endocrown, a modified overlay or crown, is considered to have the advantages of adhesive retention and mechanical retention. Marginal adaptation and mechanical strength are common criteria for evaluating endocrowns. This review studied these aspects of endocrowns to guide further clinical applic...
