[Evaluation of the alveolar curvature and the length of the mandibular ridge on skulls several hundred years old].
The alveolar curvature and the length of the curvature of the upper and lower jaw bone ridge of 338 skulls from an anthropological collection were examined with special regard to sex and side differences for designing dental implantation and jaw bone replacements. The corresponding mean values of men and women deviate at a level of 5% significance. However, in view of practical viewpoints, the difference is not significant. Data revealed that deviations of the right and left side do not exceed 1 millimeter, the jaw bone halves may be considered symmetrical. The mean value of the alveolar curvature length is 58.5 millimeters on the upper jaw bone ridge while it is 48.1 millimeter on the lower one. The lower and the upper jaw bone ridge curvature may be characterized by a circle having a radius of average 24.3 millimeter. When making implantations it seems to be advantageous to make orders of magnitude of 6, 25, 38, 25 and 6% in relation to the total number of pieces from sizes corresponding to the five class moddles.
