An application of the moiré method to three-dimensional measurements of the occlusal aspects of molars.
Moiré photographs of the occlusal surface of human molars were made by means of a specially designed apparatus for moiré contourography. Since molars show contour lines with equal intervals, three-dimensional measurement of the complicated relief of the occlusal surface is possible. The positioning of molar teeth for making the photographs and the technique of the moiré photography for small objects were presented. The three-dimensional measuring method of the molar surface and its use for anthropological purpose were discussed.
