Abstract

Five fabrication techniques and two storage methods were used to construct and store specimens to investigate the dimensional stability of acrylic resin occlusal splints. A research model was developed to more closely approximate the tooth coverage limits of occlusal splints. Ten specimens were fabricated on individual stone casts for each of the five techniques. Four die pins were transferred to each specimen, and the distances between the inside diameters of the pins were measured over a 2-week period. After construction, initial measurement, and removal from the cast, each acrylic resin specimen was stored in either a wet or a dry environment. Measurements between pins were made and recorded at five time intervals. The sprinkle-on techniques resulted in less dimensional change than the dough application, the vacuum-adapted resin sheet and dough application, and the heat-cured denture processing techniques. Acrylic resin specimens stored in a wet environment showed less distortion 2 weeks after fabrication.
