[Angle of inclination of the frontal surfaces in the axis of the lateral incisors and first lower premolars].
The angular offset of the tooth bed extensions of the upper jawbone and the mandible were evaluated in case of 280 intact skulls processed according to anthropological aspects (of 137 male, 116 female and 27 undeterminable genous). The angle measurements were carried out by goniometer between the alveolar edge of the tooth bed extensions and the root peak part, in reletion to the vertical straight at right angle to the Frankfurt horizontal plane, in the axis I. 2 on the upper jawbone, in I.2 on the mandible and in P.1. No significant differences were found between the measures either of males and females or of the right and left side. The offset angle of the front surface of the tooth bed extension showed an average value of -12.1 degrees on the maxilla in the axis I.2, 6.1 degrees on the mandible in the axis I.2 and 2.9 degrees in the P.1 axis. The data should be used for planning enossal dental implants.
