Cementation of indirect restorations: Strategies for reducing clinical failures

With advances in resin cements and the introduction of various functional monomers, esthetic indirect restorations have gradually shifted toward a bonding-based concept. These changes, along with the concept of minimally invasive dentistry, has made it possible to reduce unnecessary tooth reduction for mechanical retention and to design restorations that rely more on adhesion. Bonding of indirect esthetic restorations creates multiple interfaces among the restoration, cement, and tooth structure and depending on the type of restorative material and cement used, different clinical approaches and surface treatment strategies are required. Therefore, the success of indirect aesthetic restoration depends on an accurate understanding of each interface and the application of appropriate clinical techniques. In this report, clinical procedures for successful bonding of indirect restorations using various esthetic restorative materials will be introduced.
