| 内容記述 | To establish a novel method for orthodontic diagnosis, which integrates three-dimensional shape measurements of dental casts and morphological analysis of the craniofacial skeleton, we constructed a new reference plane, the palatal reference plane. Measurement accuracy of the palatal reference plane, and its spatial relationship to the skeletal framework of the craniofacial skeleton were evaluated using postero-anterior and lateral cephalometric radiographs and three-dimensional shape data of maxillary dental casts, which was transferred by an anatomical facebow. The results were the followings: 1. The palatal reference plane (flat area of the hard palate) could be established by a fitting algorithm with the least squares method. 2. In postero-anterior cephalometric radiographs, the angular difference between the ANS-PNS plane and the palatal reference plane was 5.58 degrees (SD : 3.48). The difference between the A-PNS plane and the palatal reference plane was 2.19 degrees (SD : 1.43). 3. In lateral cephalometric radiographs, the angular difference in angle between the maxillary alveolus plane (J-J') and the palatal reference plane was 1.09 degrees (SD : 1.05). 4. In cases whose the palatal morphology was a smooth circular arc without prominent jugum in the palatal base, it was difficult to establish the reference plane. These results indicate that the three-dimensional application of the palatal reference plane, as a reference structure, would provide orthodontic diagnosis with accurate and abundant three-dimensional data concerning malocclusions. | |||||
