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.

Three-dimensional measurements of the occlusal surface of upper first molars in a modern Japanese population.

Moiré photographs of the occlusal surface of first molars of Japanese children were taken by means of a specially designed moiré contourograph apparatus. They were then used for three-dimensional measurements. The heights of 4 cusps and some other points were measured by counting contour lines. Distances and angles between them were also measured. Sex differences of these measurements are found mainly around the metacone and hypocone. There is no clear correlation of the four cuspidal heights to the distances between them.

A three-dimensional measurement of the human parietal curvature.

The three-dimensional measurement of the parietal curvature in Japanese was accomplished with the use of moiré contourography and the sexual dimorphism was observed in it. Principal component analysis was also carried out and 4 important features of the shape of this bone were abstracted. Those were the degree of the curvature as a whole, lateral swellings, bilateral difference and posterior swelling.

Evaluation of facial osteotomy with the aid of Moiré contourography.

The Moiré method, a new technique for recording contour lines on the body surface, was applied to the evaluation of facial osteotomy in patients with oro-facial disharmony. The advantages of the methods are three-dimensional, with no contact. Small changes of the facial profile after osteotomies were measured three-dimensionally and the prediction of probable facial contour changes by osteotomies is discussed.
