| Research Abstract |
An innovative fabrication system of complete denture has been developed using digital technology: tracing and surface modeling of edentulous using an arm-type three-dimensional digitizer, computer-aided designing of special occlusal impression trays, rapid prototyping using a three-dimensional digital printer, and impression and bite registration using the special trays. The resolution is about0.6 mm in average error and about 1.0 mm in maxim error for the digital impression. It will be considered within an allowance for preliminarily impressions of total edentulous. It is suggested that a digital impression for abutment positioning in implant overdentures using digital photogeometry will be a hard target
