Factors Affecting Resin Polymerization of Bonded All Ceramic Restorations. Review of Literature.
J Dow Uni Health Sci Jan ;7(2):80-6.

Increased conservative and cosmetic dental practice has raised the demand for predictable adhesive all ceramicrestorations (Inlay, onlay, crowns and FPD). Many new bonded all ceramic systems have been introducedimproving their optical, mechanical, adhesive and working properties. As they are adhesively bonded to toothsubstrate (enamel and dentine), the resin luting cements and the adhesive interface are pivotal for their longevity.Light-cured resin cements (LCC) are often preferred due to their controlled polymerization characteristics. Asthere is no chemical curing for LCC they require sufficient light to initiate and maintain polymerization. Howeverdeep preparations and thick restorations may decrease the light intensity resulting in incomplete polymerization.Other factors like ceramic type, shade and translucency; resin cement type, composition and shade; light curingunit and method of testing similarly influence the luting resin polymerization and its investigation. Insufficientpolymerization could lead to poor mechanical and biological properties of the luting cement, compromisedmechanical characteristics of bonded ceramics and a decrease in the bond strength between tooth and restoration.This literature review will evaluate multiple factors which could potentially influence the resin polymerizationof all ceramic bonded restorations.
