Abstract

This study was designed to investigate the marginal accuracy of resin temporary crown with different matrix in indirect technique. Matrices were made from irreversible hydrocolloid impression material, putty type of vinyl polysiloxane silicone rubber and vacuum formed plastic sheet. The marginal discrepancies of the temporary crowns were measured using a measuring microscope. The obtained results were as follows 1. The marginal accuracy temporary crown using vinyl polysiloxane silicone rubber or vacuum formed plastic form was better than that of the temporary crown using irreversible hydrocolloid impression material. 2. The marginal accuracies of the temporary crown using the irreversible hydrocolloid impression material and putty type of the vinyl polysiloxane silicone rubber obtained the best results at the distal measuring point. 3. The vacuum formed plastic form was recorded a more acceptable marginal accuracy at the distal and mesial measuring points.
