Clinical guidelines for posterior restorations based on Coverage, Adhesion, Resistance, Esthetics, and Subgingival...

Restoration of posterior teeth with different extents of tissue loss has been a matter of debate in the literature. There are several recommendations and guidelines on when, how, and why to perform adhesive restorations (onlays, overlays, and endocrowns) or resistance form restorations (full-contour resistive crowns). In Part I of this three-part article series, the authors focused on adhesive partial restorations. In that article, the evidence was extensively described, and a clinically reasonable thought process was suggested for these decisions based on Coverage of susceptible cusps, Adhesion advantages and limitations, Resistance forms to be implemented, Esthetic concerns, and Subgingival management - the CARES concept. Now, in Part II, the focus is on clinical decisions for full-contour resistive crowns regarding their indications based on remaining tooth structure, materials, and different preparation designs as well as the particularities of vertical marginal preparations, perio-restorative considerations, and esthetic challenges.
