The purpose of this study was to determine the percentage of orthodontic patients who present with an interarch tooth-size discrepancy likely to affect treatment planning or results. The Bolton tooth-size discrepancies of 157 patients accepted for treatment in an orthodontic residency program were evaluated for the frequency and the magnitude of deviation from Bolton's mean. Discrepancies outside of 2 SD were considered as potentially significant with regard to treatment planning and treatment results. Although the mean of the sample was nearly identical to that of Bolton's, the range and standard deviation varied considerably with a large percentage of the orthodontic patients having discrepancies outside of Bolton's 2 SD. With such a high frequency of significant discrepancies it would seem prudent to routinely perform a tooth-size analysis and incorporate the findings into orthodontic treatment planning.
本研究的目的是确定存在可能影响治疗计划或结果的牙弓间牙齿大小差异的正畸患者的百分比。对157名接受正畸住院医师培训项目治疗的患者的博尔顿牙齿大小差异进行评估，以确定偏离博尔顿均值的频率和幅度。超出2个标准差的差异在治疗计划和治疗结果方面被视为可能具有显著性。尽管样本均值与博尔顿的均值几乎相同，但范围和标准差差异很大，有很大比例的正畸患者的差异超出了博尔顿的2个标准差。鉴于显著差异的频率如此之高，常规进行牙齿大小分析并将结果纳入正畸治疗计划似乎是谨慎的做法。
