Abstract

This study evaluates the polymerization shrinkage of two types of acrylic resins using two methods of splinting. Two implants were placed in an artificial bone, with the two transfer copings joined with dental floss and acrylic resins. Measurements of shrinkage and temperature were performed with fiber Bragg grating sensors. The results revealed that both resins showed similar shrinkage values, although one of them also showed a higher temperature increase. The measured values demonstrated that the separation and reconnection of the splinting with acrylic resin is effective at relaxing stress polymerization and reducing shrinkage polymerization.
