Abstract
Background: Adequate occlusal contacts are critical for masticatory function. The aim of this study is to evaluate the intercuspal occlusal contacts following conventional and digital wax-ups. Methods: Stone casts of 15 patients undergoing prosthodontic treatment were gathered. Each cast was duplicated twice, so that conventional and digital wax-ups could be performed. To assess the occlusion, the following variables were evaluated: contact number per tooth (CNT), contact area per tooth (CAT) and contact accuracy. Further, the impact of tooth location in the arch was assessed. Results: The CNT and CAT after the wax-ups increased significantly following each wax-up, and this increase was more..
