Research Abstract

The aim of this study is to try fabrication of crowns by laser lithography or machine of computer aided manufacturing. First we studied about processing precision and established the most suitable processing (output power of laser : 13mVV,scan speed : 240mm/s, diameter of laser spot : The 0.2 mm, product layr pace of Z direction : 0.07 mm, scan method : Normal scan). As for data of crowns, we designed full crowns using Dental CAD/CAM system which NIKON co., GC co., HITACHI co.developed. And we input it into a work station for the control of light molding device after having ontput this as Bezie curved surface patch in the cause. And then, we did setting of processing condition, a simulation and made resin model. As the results the manufacturing process that made resin model of crown for abutment tooth in the mouth of real patient was established. A form of crown made reproduced a design of CAD faithfully, too. But what was careless is regarded as future examination subject till the resinous shrinkage rate used adapts it in abutment tooth greatly.
