摘　　要：目的:探究垂直骨面型与安氏Ⅱ~1类错牙合畸形颌面骨骼及牙弓宽度的相关性。方法:选择2012年9月-2017年1月笔者医院收治的80例安氏Ⅱ~1类错牙合畸形患者为研究对象,根据垂直骨面型分为高角组(n=26)、均角组(n=28)和低角组(n=26)。观察三组上下磨牙倾斜角度和牙弓宽度。结果:就不同垂直面型患者的磨牙倾斜度进行比较,三组在下磨牙指标L6-SN、L6-PP、L6-MP,上磨牙指标U6-L6方面比较,具有显著性差异(F=32.141、52.485、20.083、57.685,P<0.05)。就不同垂直面型与牙弓宽度进行比较,三组在WU6、~6╂~6bone方面比较,具有显著性差异(F=12.395、5.027,P<0.05)。就垂直面型的颌面骨骼和牙弓宽度显著差异因子进行相关性分析,WU6、~6╂~6bone与垂直面型呈现负相关,相关系数r分别为-0.284、-0.328;而L6-SN、L6-PP、L6-MP、U6-L6呈现正相关,相关系数r分别为0.654、0.751、0.446、0.769。结论:在不同安氏Ⅱ~1类错牙合畸形垂直骨面型患者中,上颌牙弓前中段宽度随着下颌平面角的增大而减小;因此,在临床正畸过程中,需要考虑垂直骨面型。Objective To explore the correlation analysis between vertical bone profile and type Ⅱ^1 dislocation of maxillofacial bone and dental arch width. Methods From September 2012 to January 2017, 80 patients with type Ⅱ^1 dislocation in our hospital were divided into high angle group (n =26), equal angle group (n =28) and low angle group (n =26) according to the vertical facial type. Observe the inclination angle and arch width of upper and lower molars in three groups. Results There were significant differences in L6-SN, L6-PP, L6-MP and U6-L6 between the three groups (F =32.141, 52.485, 0.083, 57.685, P <0.05). There were significant differences among the three groups in Wu6 and 6╂6bone (F = 12.395, 5.027, P <0.05). Wu 6 and 6╂6bones were negatively correlated with vertical surface type (r =-0.284, r =-0.328). L6-SN, L6-PP, L6-MP and U6-L6 were positively correlated with the vertical surface type (r =0.654, r=0.751, r =0.446 and r =0.769, respectively). Conclusion In the patients with different type Ⅱ^1 heterotopic vertical bone type, the interrupted width before the maxillary arch decreases with the increase of the mandibular plane Angle.Therefore,in clinical orthodontic process,vertical bone surface should be considered.
