Abstract : Investigations are reported which apply the techniques of photoelasticity to problems in two areas of dentistry: elastic impression materials and retentive and reinforcing pins. Modeling and test techniques are reported. The effects on the final impression of type of retaining tray, bulk of impression material, and direction and speed of removal are considered. Stress distributions developed as a result of installation of multiple pin restorations have been determined and aspects of standardization of pin installation techniques are presented. (Author)
