Three-dimensional Measurements of the Occlusal Surfaces of Upper Molars in a Dutch Population

Abstract

The occlusal surfaces of the first upper molars of a Dutch population were measured three-dimensionally by moire contourography. Cusps and ridges were higher than those of a Japanese population, but distances between cuspal tips were smaller. Differences in occlusal form may influence jaw movements in the two populations.
