Abstract : Several empirical claims appear in the literature for improved dimensional stability when utilizing a particular fabrication technique for interocclusal orthopedic (Dental Protheses) stabilization appliances. The primary objective of this study was to utilize five specific fabrication techniques and two storage methods to construct and store acrylic resin specimens, and to visualize and quantify their linear dimensional change over a two week time period. An original research model was developed to approximate more closely the tooth coverage limits of removeable acrylic resin orthoses. Four pindex pins were transferred to each individual specimen and measurements were made of the distances between the inside diameters of the pins. Ten specimens were fabricated on individual die stone casts for each of the five techniques. After construction, initial measurement, and removal from their cast, each specimen was stored in either a wet or dry environment for the duration of the study. Measurements between pins were made and recorded at five time intervals.
