Learning the widely differing forms of tooth preparation, especially in restorative dentistry, places high demands on both trainees and instructors with regard to precision, reproducibility, assessment, evaluation and three-dimensional conceptualization. In the past, evaluation of such preparations has been against subjective parameters and their interpretation by the assessor (usually the instructor). The use of CAD systems in teaching seminars and courses allows an objective assessment of tooth preparations and offers the trainee the possibility of measuring him/herself against a standard, of detecting errors, and of achieving perfection in the required tasks. The PREPassistant system described in this article is one such CAD-assisted learning system. It is recommended both for students in dental schools and for the continuing education of established dentists. Its strengths are that it produces a design for a tooth preparation, enables exact comparison with an ideal preparation, detects errors, and promotes improvements and perfection.
学习各种差异很大的牙齿预备形式，尤其是在修复牙科学中，对学员和教员在精度、可重复性、评估、评价以及三维概念化方面都提出了很高的要求。过去，对这类预备的评估一直基于主观参数以及评估者（通常是教员）对这些参数的解读。在教学研讨会和课程中使用CAD系统可以对牙齿预备进行客观评估，并为学员提供了对照标准衡量自身、发现错误以及在所需任务中达到完美的可能性。本文所描述的PREPassistant系统就是这样一种CAD辅助学习系统。它既推荐给牙科学校的学生，也适用于执业牙医的继续教育。其优势在于它能生成牙齿预备的设计，能够与理想的预备进行精确比较，检测错误，并促进改进和完善。
