Background and objectives: Dimensional changes associated with the processing of complete dentures is one of most important problems of acrylic resin denture base materials, these changes lead to series of problems clinically. The aim of this study was to try new attempts to minimizing the post processing dimensional changes.
Methods: Forty-two identical maxillary waxed dentures prepared, each of them mounted on an articulator. The initial dimension was measured between the upper and lower members of the articulator before processing, after processing and remounting of the dentures the measurements recorded after deflasking and decasting, comparing these measurements with the initial measurement determined the incisal pin opening (IPO). Two new attempts for decreasing IPO have been tested by modifying the conventional waxed dentures, in the first attempt five wax sprues added to the flanges while in the second attempt four wax sprues added to the palatal surfaces of the waxed dentures. The waxed dentures processed in two types of heat curing acrylic resins.
Results: The results showed that both new attempts caused decreasing in the dimensional changes and IPO at both times after deflasking and decasting.
Conclusion: It had been concluded that the addition of four waxed sprues will significantly decrease the IPO.
