The purpose of this study was to evaluate the changes in orthodontic care patterns over a sixteen-year period in a university clinical setting. The average numbers of students, clinical procedures, and orthodontic appliances were examined from the time period 1988-2003. Appliance number and type were evaluated as a function of increased predoctoral and postdoctoral class sizes, student to faculty ratios, and decreased operating budgets for faculty recruitment. For the period 1988-98, the insertion of orthodontic appliances by dental students remained constant. A permanent increase in the predoctoral class size occurred in 1996 without an increase in faculty support, contributing to a decline in appliance insertions by students from 1999 to 2003. This time period also saw major increases in the postdoctoral class size and a reorganization of the clinical facility that then began to require the pairing of dental students to provide comprehensive care, thus decreasing their clinical exposure to the care of children. The overall clinical experience at the predoctoral level in orthodontic procedures declined, which resulted in a change in clinical requirements and new methods to ensure clinical competency.
本研究的目的是评估在一所大学临床环境中十六年间正畸治疗模式的变化。对1988年至2003年期间的学生平均人数、临床操作以及正畸矫治器数量进行了考察。矫治器的数量和类型是根据博士前和博士后班级规模的增加、学生与教师的比例以及用于教师招聘的运营预算减少来评估的。在1988 - 1998年期间，牙科学生安装正畸矫治器的数量保持不变。1996年博士前班级规模永久增加，但教师支持并未增加，导致1999年至2003年学生安装矫治器的数量下降。这一时期博士后班级规模也大幅增加，临床设施进行了重组，随后开始要求牙科学生配对以提供全面护理，从而减少了他们对儿童护理的临床接触。正畸程序中博士前水平的整体临床经验下降，这导致了临床要求的改变以及确保临床能力的新方法。
