Bonded ceramic restorations rely on adhesion to allow for both retention as well as performance under function. Achieving an extremely strong, durable bond is desirable because it allows stresses to pass more uniformly and efficiently through the restoration to the underlying tooth structure. Thereby, the restored tooth-restoration complex mimics the function of intact, natural teeth and is said to behave biomimetically (“mimicking nature”). From an engineering standpoint, this maximum-adhesion can be obtained when surface preparation, cleaning, and conditioning are each maximized. This lecture covers a variety of techniques to optimize the bond to ceramic, enamel, and dentin. Additionally, the cementation protocol, materials, and techniques are reviewed to achieve a reliable, biomimetic bond.
