Purpose. To determine the effect of interocclusal recording material on the occlusal accuracy of mounted stone casts.
Materials and methods. A dentoform mounted on an articulator served as the simulated patient (control). Derived dental stone casts were mounted using different interocclusal recording material; polyvinylsiloxane (trimmed and untrimmed), bis-acrylic resin (trimmed and untrimmed), and wax. A polyvinylsiloxane scanning registration was made of the occlusal aspect of each mounted cast. The registrations were scanned for optical density and contacts were quantified as actual contact and near contact. Non-parametric tests were used.
Results. Derived stone casts mounted with different recording materials displayed significantly different occlusal contacts compared to the simulated patient.
Conclusions. Although wax interocclusal records displayed the most accurately mounted casts among the materials tested, a patient’s occlusion cannot be duplicated from derived stone casts mounted with interocclusal record material evaluated in this study.
