Abstract:

Rapid development of CAD/CAM technologies has been observed in recent years. Adhesion of indirect restorations to hard dental tissues is influenced by two factors—the treatment of the internal surface of the restoration and the cement. The cementation of indirect partial restorations (inlay, onlay, overlay, veneers) is one of the most important steps in restorative dentistry The cement agent bonds enamel/dentin to the restorative material. The most commonly used cements are resin based. Composite cements used to lute indirect aesthetic restorations could be classified as total-etch, self-etching and self-adhesive. There is no luting material that can be universally used. Adhesion of extensive partial aesthetic restorations like veneers and overlays depend on the adhesive bond to the hard dental tissues by the adhesive cement and not so much on the retention forms of the prepared tooth. Therefore, it is important to know the quality and properties of cements in order to choose the best one for each clinical case. This study presents an overview of the types of composite cements, the protocol for their application, type of bond, their advantages and disadvantages.
