하악과두 전위로 인한 두부방사선계측의 변화에 관한 연구

A study on the cephalometric changes by the displacement of the mandibular condyles

To determine the difference in cephalometric measurements between centric relation and centric occlusion, 60 patient-20 patients for each malocclusion group-were examined with the cephalograms in centric relation and in centric occlusion. The results are as follows: 1. There are differences in cephalometric measurements with the mandible in the two different position, and some measurements are statistically significant. 2. No clinically useful prediction may be made from cephalometric radiographs concerning the amount of mandibular deflection from centric relation to centric occlusion. 3. If, the large differences in the cephalometric measurements with the mandible in the two different position, the analysis with the cephalogram in centric occlusion is needed to be compensated with the other clinical approach.
