Abstract

In dental education root canal treatment is primarily trained with natural teeth models or transparent acrylic blocks. A newly constructed, 3D printed practice tooth can be produced cost-efficiently and reproducibly while based on a natural root canal anatomy. Based on a micro-CT scan of an extracted tooth number 36, a dataset was reconstructed (Autodesk Inventor 2019, Autodesk Inc.) and subsequently 3D printed (Form 3B, Formlabs Inc.). In a hands-on course, dental students performed root canal treatments on 3D printed practice teeth. The practice teeth were prepared and filled. A reciprocating system (Reciproc, VDW GmbH) and a rotating preparation system (Pro Taper Next, Dentsply Sirona GmbH) were utilized. Students completed a questionnaire to evaluate practice materials, learning success, and learning process. The students rated suitability as a practice option (p < 0.001) and handling (p = 0.001) of the 3D printed practice tooth, as well as natural tooth models, significantly better than acrylic blocks.

摘要

在牙科教育中，根管治疗主要使用天然牙齿模型或透明丙烯酸块进行培训。基于天然根管解剖结构，可以经济高效且可重复地生产一种新构建的3D打印练习牙。基于对一颗拔除的36号牙的显微CT扫描，重建了一个数据集（Autodesk Inventor 2019，Autodesk公司），随后进行3D打印（Form 3B，Formlabs公司）。在一门实践课程中，牙科学生在3D打印的练习牙上进行根管治疗。对练习牙进行预备和充填。使用了往复系统（Reciproc，VDW GmbH）和旋转预备系统（Pro Taper Next，登士柏西诺德有限公司）。学生们完成了一份问卷，以评估练习材料、学习成果和学习过程。学生们对3D打印练习牙以及天然牙齿模型作为练习选项的适用性（p < 0.001）和操作便利性（p = 0.001）的评价明显优于丙烯酸块。
