Abstract. As 3D scanner and 3D printer develop, 3D related researches are being progressed in medical and other industrial fields.   Amalgam is used to most restoration in dentistry field. However amalgam has esthetic negative element because of the metallic color. Thus esthetic materials such as ceramic usage have been increased. 3D virtual model is required for ceramic manufacture different from existing amalgam manufacture. Therefore existing dental impression models are being scanned for converting the actual model to 3D virtual model. Generally when 3D scanner used in dental technical laboratory is scan the dental impression as shown in Figure 1, swing and rotation angle can be adjusted to search the better scan direction. Decision of scan direction depends upon the user experience. However they work inefficiently because most users do not have 3D related expertize. So this paper propose that the automated detection of 3d scanning direction for dental impression model.
