抄録

The indirect method of full cast crown construction has been constantly improved by the introduction of new dental materials and impression techniques. However, the ideal materials and a technique for making crowns with a complete marginal fit have not been developed yet.<BR>The purpose of this study was to clarify the influence of the indirect method on marginal fit of crown by altering various factors.<BR>1. Conventional or fast-setting gypsum-bonded investments.<BR>2. Three different types of impression materials: addition silicone with individual tray, double-mixed addition silicone and agar with irreversible hydrocolloid.<BR>3. Water-saturated or dry ring lining material.<BR>A microscope was used to measure the fit of castings. The fit of castings was defined as the casting margin difference from the original position when they were tried on a steel die.<BR>The fit of castings made in the method using fast-setting gypsum-bonded investment was looser and the marginal difference was significantly smaller than that using conventional gypsum-bonded investment irrespective of the impression material and usage of ring lining materials.
