摘要: 目的:运用Andrews口颌面协调六要素中的GALL线,尝试对快速扩弓联合前方牵引矫治骨性Ⅲ类错牙合的疗效评价分析。方法:共选取25名扩弓前牵矫治结束的7~12岁骨性Ⅲ类错牙合患者(男12,女,13),以GAll线作为参考平面分析矫治前(T1)和治疗后(T2)的头颅侧位片,并以传统的评价指标为对照,评价矫治前后软硬组织的变化。结果:治疗结束后,患者均发生了明显的上颌骨前移,下颌骨后移.SNA、ANB、PP-FH、MP-FH、L1-MP、U1-SN、MP-FH、B-GALL 、Pog-GALL、 U1FA-GALL、U1-GALL、L1-GALL、LL-E、LL-GALL、Ns-Sn-Pos治疗前后的数值,差异有统计学意义(P<0.05),SNB、Wits值、Y轴角治疗前后差值无统计学意义。结论:以GAll线为参考平面的测量指标的结果与传统评价指标大的结果基本一致,这种基于面部协调美学理论的评价方法能够有效直观的反映出错患者扩弓牵前矫治后的牙、颌、面关系的改善,较传统的评价测量方法更加直观及个性化。

Abstract: Objective: To make an analysis on the appearance change after rapid maxillary expansion combined with maxillary protraction based on Andrews six elements of oralfacial harmony. Methods: A total of 25 patients with maxillary deficiency were collected. Before and after the treatments, cephalometric radiographs were measured using GAll line as a reference plane. The measuring results were compared with traditional evaluation index. Results: After treatment, all patients had obvious maxillary anterior displacement and mandibular posterior displacement. The differences of SNA, ANB, PP-FH, MP-FH, L1-MP, U1-SN, MP-FH, B-GALL, Pog-GALL, U1FA-GALL, U1-GALL, L1-GALL, LL-E, LL-GALL, and Ns-Sn-Pos before and after treatment were statistically significant. However, the differences of SNB, Wits, and Y axis were not statistically significant. Conclusion: The results of measurement indexes using GAll line as the reference plane were basically consistent with the results of traditional evaluation indexes. This evaluation method could effectively and intuitively reflect the improvement of the relationship among teeth, jaw, and face after the orthodontic treatment.
