Standard Markers of Vertical Alignment of Mandible and Maxilla in Adult Population of the Syrian Coast


Abstract in English

The craniofacial complex is affected by both vertical and sagittal changes. However, previous studies did not consider the changes presented by the bone bases of both mandible and maxilla in the vertical plane in the case of the adult population of the Syrian Coast, with normal permanent occlusion. Aim: is to study the degree of correlation between the cephalometric parameters which have been considered by previous studies as real indicators for the vertical alignment of the mandible and maxilla with each sex, and determine their standard values to be able to classify the facial morphology in the vertical plane into 3 patterns (long face, medium face, and short face) in the population of the Syrian Coast with permanent normal occlusion. Materials: 106 lateral cephalometric x-rays of adult patients with permanent normal occlusion, without prior orthodontic treatment were used (46 males, 60 females) from the archive of the Orthodontics and Dentofacial Orthopedics Department at Tishreen University. The age ranges were between 13-30 years old. The cephalometric tracing was carried out by hand and the cephalometric measurements that have been considered by previous studies as real indicators for the vertical alignment of the mandible and maxilla were taken. Results: There were no statically significant differences between the two sexes for the Cephalometric parameters that have been considered by previous studies as real indicators for the vertical alignment of the mandible and maxilla, standard values of the population of the Syrian Coast with permanent normal occlusion for the vertical alignment of the mandible and maxilla were obtained which were very close to the values received in previous studies, though there have been observed some variations.
