[Mandibular positions in complete dentures according to the calotte principle]

A total of 37 patients was provided with complete dentures according to the calotte system. Two groups were formed with regard to the arrangement of the anterior teeth. After a mean period of wear amounting to 13 months different positions of the mandible were recorded in 21 patients under the guidance of a central bearing point and in occlusion. Patients with an arrangement of the anterior teeth free of interferences in excursive movements exhibited a significantly lower distance habitual occlusion/retruded position than subjects with an overlap limiting sagittal freedom. Therefore, an arrangement of the anterior teeth integrated into the calotte complex respectively free of interferences in eccentric positions is to be preferred.
