[摘要] 目的 对单颌和双颌拔牙矫治安氏Ⅱ类1分类错■的疗效进行比较。方法 方便选取该院2010年2月—2017年3月收治的50例安氏Ⅱ类1分类错牙合患者,按照患者矫治意愿分为观察组与参考组各25例,其中观察组接受上颌单牙合拔牙矫治方案,参考组接受双颌拔除4个前磨牙矫治方案,分别在治疗前、后观察两组患者X线头影测量结果。 结果 矫治前两组患者U1-FH、U1-AP、H角、UL-E、 LL-E 距离、Z角、SNA、SNB、ANB比较差异无统计学意义(P>0.05);治疗后两组患者U1-FH、U1-AP、H角、UL-E、 LL-E 距离、Z角指标均出现明显变化(P0.05),观察组患者U1-FH、U1-AP、H角减小程度明显大于参考组(P0.05);观察组矫治疗程为(22.13±4.53)个月,与参考组的(22.65±5.01)个月比较差异无统计学意义(P>0.05)。 结论 单颌与双颌拔牙矫治安氏Ⅱ类1分类错牙合能够使上前牙内收,使软组织侧貌很大程度改善,然而单颌拔牙矫治方案效果更佳,可在临床推广使用。

treatment of class II Division 1 malocclusion. Methods 50 cases of class II division 1 malocclusion
from Febuary 2010 to march 2017 were convenient selected and divided into the observation group
and the reference group, with 25 cases in each group, according to the treatment methods. The
observation group received single maxillary tooth extraction treatment scheme, the reference group
received bimaxillary extraction of four premolars, cephalometric results before and after treatment
of the two groups respectively were observed. Results U1-FH, U1-AP, UL-E, H angle, Z
angle, LL-E distance, SNA, SNB, ANB of patients in the two groups before treatment had no
significant difference(P>0.05); U1-FH, U1-AP, UL-E, H angle, LL-E distance, Z angle
