The purpose of this study was to evaluate the fabrication of a complete denture using a CAD/CAM system. Cone beam CT was used to measure the complete denture and the artificial teeth. After a 3D complete denture image was structured using 3D CAD software, we factored out the artificial teeth and obtained a 3D denture base image. A machining center cut an acrylic resin block, and fabricated an a...

introdouction: the aim of this study was to compare the ratios of the mesiodistal width of the upper and lower central incisors between natural teeth and those produced artificially by ideal makoo, ivoclar, and vitapan, in iran. materials and methods: the mesiodistal width of the upper and lower central incisors was measured in 120 students, using calipers placed at the height of contour of the...

Crossliked plastic denture teeth have been used clinicaly in order to improve the poor wear resistance of conventional acrylic denture teeth. We suggest that highly crosslinked denture teeth are possibly disadvantaged compared with conventional ones, when considering the adhesion to denture base and impact resistance. The purpose of this study is to evaluate the impact resistance of crosslinked...

This study explored a method for fabricating removable complete denture aided by CAD&RP technology. 3D crossing section scanner and laser scanner were respectively applied to obtain the surface data of artificial teeth, edentulous models and rims made in clinic. The vertical and horizontal relations of models were recorded before scanning with a special device. A 3D graphic database of artifici...

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.

Although different commercial brands of artificial teeth are available in the market, debonding from the denture base is still an issue when rehabilitating edentulous patients with conventional or implant-supported complete dentures. The purpose of this study was to investigate the effect of surface treatments on the bond strength of four artificial teeth brands to a denture base material polym...
