儿童骨性下颌偏斜患者的牙弓形态及颌骨对称性分析
The arch form and mandibular symmetry in patients with skeletal mandibular deviation
摘要
Abstract
Objective:To study the arch form and mandibular symmetry in the children with skeletal mandibtdar deviation.Method:13 patients with skeletal mandibular deviation were selected.Midline of palatal was defined as central line.The distance was measured in each side and the dental arch symmetry was observed.Then the mandibular ramus heighl,the length of the mandibular body and the combined length of the mandible were measured on the X-ray radiograph.Result:Upper arch was asymmetric in these patients,the arch of the deviated side (the side that the chin deviated to) was broader than the other side （P ＜ 0.05).The mandibular ramus height and the combined length of the mandible on the deviated side were significantly smaller than the other side (P ＜ 0.05).But there was no significant difference between the two sides about the mandibular body (P ＞ 0.05).Conclusion:Obvious mandibular asymmetry was found in the patients with skeletal mandibular deviation,which resulted in the compensation of the dental arch and teeth to some degree.Comprehensive analysis is needed in the clinical treatment.关键词
