A revision of the Hixon and Oldfather prediction method was undertaken with measurements obtained from persons who participated in the Iowa Facial Growth Study, the same group of subjects used originally by Hixon and Oldfather to develop their prediction equation. A significantly improved prediction equation was developed. A graph was made for clinical use in the prediction of mandibular canine and premolar widths in mixed-dentition patients.
利用从参与爱荷华面部生长研究的人员身上获取的测量数据，对希克森和奥尔德法瑟的预测方法进行了修订，这些受试者与希克森和奥尔德法瑟最初用于推导其预测方程的是同一组。由此得出了一个显著改进的预测方程。绘制了一张图表，供临床用于预测混合牙列患者的下颌尖牙和前磨牙宽度。
