The purpose of this study was to investigate changes in the palatal form in patients treated with and without premolar extractions. Records collected at pretreatment, at bracket removal, at the end of retention, and 5 years out of retention were examined. Stone casts were mounted on an articulator with an anatomic face-bow and a central wax record, and measurements were made with a 3-dimensional digitizer. The hypothesis that orthodontic treatment with premolar extractions changes the palatal form was verified.
本研究的目的是调查拔牙和不拔牙治疗患者的腭部形态变化。检查在治疗前、去除矫治器时、保持结束时以及保持结束5年后收集的记录。将石膏模型用解剖面弓和正中蜡记录固定在架上，并用三维数字化仪进行测量。拔牙正畸治疗会改变腭部形态这一假设得到了验证。
