Abstract
There are a wide variety of cementation materials available for use in clinical dentistry. Four commonly used cements are zinc phosphate cement, zinc polycarboxylate cement, glass ionomer cement and zinc oxide-eugenol cement. As a luting medium these cements are directly interposed between a precision casting and the prepared tooth surface. It is therefore essential in clinical situations that they form a thin, uniform, occlusive layer. Any properties of a cement which result in increased film thicknesses during clinical applications can impair the fit of a crown leading to occlusal problems, loss of retention, marginal breakdown and eventual failure of intended treatment. Information concerning a cement's individual film thickness and how that film thickness compares to other cements designed for similar use is of vital importance to patient treatment procedures.
The study presented in this paper is designed to investigate the seating characteristics of full coverage crowns while using zinc phosphate, zinc polycarboxylate, glass ionomer and zinc oxide-eugenol cements. Two different methods of load application are used to seat the crowns. One of these is constant and the other is a tapping force. By studying differences in the manner in which crowns behave while being seated with different cements and under different loading conditions, it is hoped that we will be better able to evaluate these cements in terms of how they behave under a certain set of clinical conditions.
