摘要：

背景：研究表明，覆盖在硬组织之上的软组织的厚度存在有较大的差异，不是均匀地覆盖在硬组织之上，即临床治疗错牙合畸形时，仅仅单纯进行硬组织测量将不能获得理想的侧貌外形。
目的：分析成人Angle II类错牙合软硬组织颅面结构特征，并分析Angle II1类与II2类软硬组织相关性。
方法：从2011至2014年佳木斯大学附属口腔医院正畸科门诊病例中选取成人Angle II类错牙合畸形患者60例，年龄在18-38岁之间，平均26.3岁，男女各半，其中Angle II1类和II2类各30例，采用计算机X射线头影测量技术对比分析Angle II1类和II2类错牙合畸形软硬组织测量项目的差异以及其软硬组织相关性。
结果与结论：①硬组织测量结果：两组患者SNB角(蝶鞍中心点、鼻根点及下齿槽座点所构成的角)、SND角(蝶鞍中心点、鼻根点及下颌联合部中心点所构成的角)、ANB角(上齿槽座点、鼻根点与下齿槽座点构成的角)、面角(FH-NP)、上中切牙角(U1-SN，P < 0.001)、LI-NB角(P < 0.01)、下中切牙角(L1-MP，P < 0.01)、上下中切牙角(U1-L1，P < 0.001)的差异有显著性意义(P < 0.05)。②软组织测量结果：两组患者上唇倾角(ULA’ -FH)、下唇突角(LLNs-FH)、上唇突角(ULNs-FH)、鼻唇角(CmSnUL)、下唇-审美平面距(E-LL)的差异有显著性意义(P < 0.05)。③两组患者软硬组织各测量项目间有相关，相关性高低存在差别。结果表明AngleII1类错牙合的上颌骨及上前牙的突度对下唇部的位置有一定的影响。而Angle II2类只有上颌突度对下唇部软组织的位置的影响。Angle II2类错牙合颏部软组织变异较小，而Angle II1类错牙合的颏部软组织变异较大。临床治疗成人Angle II类错牙合畸形患者制定方案时，需结合其各自的软硬组织结构特点进行正畸、正颌外科治疗以及方案的制定。

Abstract:

BACKGROUND: Studies have shown that there are large differences in the thickness of the soft tissue overlying hard tissue, and the soft tissue does not uniformly overly the hard tissue, indicating simple hard tissue measurement will not harvest ideal facial profile in clinical treatment of malocclusions.
OBJECTIVE: To study the craniofacial soft and hard tissue characteristics in the adult Angle class II malocclusion, and then to analyze the relationship between Angle class II1 and class II2 malocclusions.
METHODS: Sixty patients with adult Angle II malocclusion who were accepted by the Department of Orthodontics of Stomatological Hospital Affiliated to Jiamusi University from 2011 to 2014, on gender parity, aged 18-38 years 
(mean age of 26.3 years), including 30 cases of Angle class II1 and 30 cases of Angle class II2. Differences between the adult Angle class II1 and class II2 malocclusion patients were compared by cephalometric analysis based on X-ray measurement. Statistical correlation analysis was performed.
RESULTS AND CONCLUSION: (1) Comparisons of hard tissue measurement of adult Angle class II1 and Angle class II2 malocclusions showed that: SNB, SND, ANB, FH-NP, U1-SN (P < 0.001), LI-NB (P < 0.01), L1-MP (P < 0.01), U1-L1   (P < 0.001) exhibited statistically significant differences between two groups (P < 0.05). (2) Comparisons of soft tissue measurement of adult Angle class II1 and Angle class II2 malocclusions showed that: there were significant differences in the ULA'-FH, LLNs-FH, ULNs-FH, CmSnUL, E-LL (P < 0.05). (3) There was a correlation between the soft and hard tissue of adult Angle class II1 and Angle class II2 malocclusions in all measurement indexes, but the correlativity exists differently. These findings indicate that for Angle class II1 malocclusion, the maxillary and anterior teeth protrusions have a certain influence on the position of the lower lip; for Angle class II2 malocclusion, only maxillary protrusion can impact the position of the soft tissue of the lower lip. Chin soft tissue has no major changes in Angle class II2 malocclusion, but it varies greatly in Angle class II1 malocclusion. Clinical treatment of adult Angle class II malocclusions is developed based on the craniofacial soft and hard tissue characteristics in orthodontic and orthognathic surgeries.
