目的：通过对骨性Ⅲ类错（牙合）患者硬组织面型聚类分析，研究各亚类软硬组织面型间的差异，加深对骨性Ⅲ类错★患者面型构成的认识。方法选择344例18~25岁女性骨性Ⅲ类错★患者为研究对象，在头颅侧位片上测量反映软硬组织面型的22项指标，根据硬组织面型特征进行聚类分析，研究各亚类软组织面型特征，进行软硬组织面型的相关分析。结果聚类分析将骨性Ⅲ类错★患者分为10个亚类，有40%的骨性Ⅲ类错★患者软硬组织矢状面型不一致，在上颌发育不足、下颌基本正常和上下颌均发育不足亚组中直面型构成比接近50%。软组织面型特征与矢状骨面型关系较大，垂直骨面型特征对软组织面型影响较小。结论面部硬组织是构成软组织面型的基础，但是各亚类骨性Ⅲ类错★患者软组织代偿能力不同，要针对患者各自的特点设计矫治方案。
