PROBLEM TO BE SOLVED: To provide a method for creating dental prosthesis capable of three-dimensionally measuring a shape of an oral cavity so as to be able to manufacture a dental prosthesis with higher compatibility accuracy, without spraying powder even, when an existing device is used.SOLUTION: A polymerizable composition (3) for manufacturing dental prosthesis is applied to the surface of a cavity or an abutment tooth (1). The composition for manufacturing dental prosthesis is hardened, and an outer surface shape of the hardened composition for manufacturing dental prosthesis is three-dimensionally measured in a non-contact manner. The composition for manufacturing dental prosthesis has a glossiness of 20 or less when it is hardened to be a hard body having a thickness of 2 mm.SELECTED DRAWING: Figure 3【課題】これまでの装置を用いる場合であっても、パウダーの噴霧をすることなく、更に適合精度が高い歯科補綴物を作製することが可能となるように口腔内の形状を三次元的に測定することができる歯科補綴物の作製方法を提供する。【解決手段】窩洞又は支台歯（１）の表面に重合性の歯科補綴物作製用組成物（３）を塗布し、該歯科補綴物作製用組成物を硬化させ、硬化した歯科補綴物作製用組成物の外表面形状を非接触で三次元形状計測する過程を含み、歯科補綴物作製用組成物は、厚さ２ｍｍの硬化体としたときの光沢度が２０以下である。【選択図】図３
