3、描(CBCT)测量值。方法:回顾性选择2017年1月-2018年5月笔者医院口腔正畸科收治的100例安氏H类1分类错牙合畸形患者为研究对象,均在CBCT引导下行微种植体支抗拔牙矫治,观察患者矫治前、矫治中期及矫治后中切牙处牙槽骨指标、软组织指标、牙槽骨高度及牙根体积。结果:矫治前、矫治中期及矫治后,患者 UA、LA、LP、LA+LP、UA+UP、ULP、UL-EP、LLP、LL-HLine, LL-EP、HA 逐渐降低,而患者 LAH、ULL、LLL、Ns-Sn-Pos. NLA、SL-HLine及舌侧、唇侧、远中、近中牙槽骨高度逐渐升高(P0.05)。结论:CBCT引导下行微种植体支抗拔牙矫
4、治,可提高矫治方案的科学性、准确性,有效改善安氏II类1分类错牙合畸形患者中切牙处牙槽骨指标及软组织指标水平,提高牙槽骨高度,降低牙根吸收,在患者矫治中的应用价值显著。Key错牙合畸形;安氏H类1分类;CBCT;微种植体;牙槽骨;软组织;牙根吸收口 R783.5文献标志码A 1008-6455 (2021) 10-0129-04Analysis of CBCT Measurements before and after Orthodontic Correctionin Patients with Class II Division 1 MalocclusionSHEN Yuel, ZENG C
