Bonding of indirect restoration

Abstract

The bonding of indirect restorations with crowns and prostheses has many benefits not only in restoring morphology and function, but also in prolonging tooth life and preventing disease. The adhesive bonding of restorations is affected by the two bonding surfaces of the adhesive resin cement, the abutment side and the restoration side, as well as the physical properties of the resin cement itself. The bonding surfaces on the abutment side can be enamel, dentin, metal, or composite resin, depending on the case. On the other hand, those on the restoration side are diverse, including metals (precious and non-precious), ceramics (glass and zirconia), and resin-based materials such as composite resins, CAD/CAM crown materials, and PEEK materials. Differences in characteristics of the bonding surfaces must be taken into consideration.
