A comparison of gingival marginal gap formation in composite inlays using three different fabrication techniques.
The purpose of this study was to evaluate the accuracy of composite inlays fabricated with three different techniques. Using 2-factor ANOVA it was found that after light curing, the Direct Method was the most accurate. After readapting and heat curing, the Indirect Method was not different from the Direct Method. The same was true after 24 hours' storage in water. The direct method is recommended if proximal contours and contact can be adequately controlled. If an Indirect Method is used, it is recommended that the laboratory use an additional cured layer of composite material in the gingival margin after initial curing to minimize the gaps.
