摘要目的 通过比较安氏II1与安氏II2错(牙合)Bolton指数及Bolton不调量,探讨两类错(牙合)在上下颌牙量关系方面的差异.方法 以安氏II1错(牙合)129例,安氏II2错(牙合)81例为研究对象,分别对其模型进行牙冠宽度测量,计算Bolton指数,再根据Bolton指数正常值获取上颌Bolton不调量.两组之间进行统计学分析.结果 ①安氏II2错(牙合)全牙Bolton指数比值(0.92±0.02)大于安氏II1错(0.91±0.02),差异有统计学意义(P=0.044),而两类错间前牙Bolton指数比值的差异无统计学意义(P=0.240).② 安氏II2错(牙合)前牙Bolton不调量(1.05±0.96)大于安氏II1(0.73±0.60)错,差异有统计学意义(P=0.044),而全牙Bolton不调量的差异无统计学意义(P=0.664).结论 两类错(牙合)在Bolton指数及Bolton不调量方面存在差异,在治疗时应该加以重视. Objective To compare the Bolton index and Bolton tooth size discrepancies between Class II1 and Class II2 cases. Methods 129 casts of Class II1 patients and 81 casts of Class II2 patients were selected. Mesiodistal width of teeth was measured and Bolton index was calculated. According to Bolton rate standards, the tooth size discrepancies were calculated. Statistical analysis was made between these two groups. Results ① The total Bolton index in Class II2 cases (0.92±0.02) was significantly larger than that in Class II1 cases (0.91±0.02),(P=0.044). There were no significant differences of the anterior Bolton index between these two classes of malocclusion (P=0.240). ② The anterior Bolton tooth size discrepancies in Class II2 patients (1.05±0.96) were significantly larger than that in Class II1 patients (0.73±0.60), (P=0.044). There were no significant differences of the total Bolton tooth size discrepancies between the two classes (P=0.664). Conclusions There were differences of the Bolton index and Bolton tooth size discrepancies between Class II1 and Class II2 patients.
