Occlusal plane orientation with an extracranial posterior point of reference
Abstract
This study was carried out to compare the location of occlusal plane, which exists in the natural dentition with the prosthetic occlusal plane when oriented according to Camper's line. Lateral cephalometric radiographs were obtained form (106) dentate subjects using a standard radiological technique. The results showed a variation between the orientation of the two planes. The plane extending from inferior border of ala of the nose to the inferior border of external auditory meatus was found to be reliable for the determination of occlusal plane of the artificial teeth.
