In vitro evaluation of basal shapes and offset values of artificial teeth for CAD/CAM complete dentures

• We evaluated optimal shape of artificial teeth for CAD/CAM complete dentures.
• We examined the optimal offset values required for teeth positioning.
• The structures in the basal areas showed accurate positioning for molars/premolars.
• The structures appeared to restrain motion during bonding.
• The optimal offset value was .20 mm for molar and premolar teeth.

Statement of Problem. Artificial teeth are bonded onto the recesses of a milled denture base in a complete denture prepared using computer-aided design/computer-aided manufacturing (CAD/CAM). Little is known, however, about the effects of basal shapes and offset values on the accuracy of positions of the bonded artificial teeth.
