For the manufacture of a fitting member, such as for a dental prosthesis, the invention proposes for the reception part receiving the same and in order to adapt to the remaining stump, a method and an apparatus in which an optical groove grating is repeatedly projected with a slight local offset onto the reception part and the photograph is used for calculating the fitting member. According to the invention the photograph of the optical groove grating projected onto the reception part takes place by means of a matrix camera for producing moire fringes and between the optical groove grating and the reception part there is an optical deflecting device for separating the illuminating beam path impinging through the groove grating and the output beam path emanating from the reception part and recorded by the camera, the camera being a matrix camera for producing moire fringes.
