A system to provide quantitative information on the angle between dentition and face was developed using a three-dimensional (3D) integrated configuration measured by a non-contact 3D digitizer. The integrated configuration angles between the Camper's plane and occlusal plane on the sagittal and the horizontal projected planes were obtained. Clinical application for a patient to improve the tegmenta of the anterior tooth by setting a temporary bridge on her lower dentition was attempted. Her dentition and face were measured on her first visit and after treatment, and 3D data of them were integrated. The quantitative change of the angle between the Camper's plane and lower occlusal plane were successfully analyzed by the present system, and after treatment, rotation of the lower occlusal plane for 1° in a clockwise direction on the sagittal plane projection, and that for 1° in a counterclockwise direction on the horizontal plane projection relative to the Camper's plane were detected.
