Abstract

|
|
This study was designed to compare the craniofacial structure of orthodontic patients with that of normal adult. For that purpose, 61 male and 64 female adults with normal occlusion were selected and utilizing the cephalogram that had taken under the natural head position and computerized graphic image, the spacial position of each anatomical structure against true horizontal-and vertical reference plane was investigated.
The following results were obtained.
1. The absolute spacial positions of each anatomic structure were calculated.
2. The inclination of Sella-Nasion plane to true horizontal plane was 8.3° ± 3.9 in male and 9.3°
3.2°´ ins female.
3. The inclination of Frankfort horizontal plane to true horizontal plane was 1.3° + 3.0° in male and 1.7° ± 3.0° in female.
4. The dimensions of Nasion-sdlla and Nasion-Anterior nasal spine to be used as the basic units of mesh diagram were 70.7mm ± 3.1mm, 61.8mm ± 2.7mm in male and 67.8mm ± 3.3mm, 57.pmm ± 2.6mm in female respectively.
5. The standard templates of craniofacial structure´ of male and female adult normal group were constructed.
6. The mesh ; diagrams of craniofacial structure of male and female adult normal group were constructed.
