Computer-aided design/computer-aided manufacturing (CAD/CAM) of fixed prosthetic restorations has gained popularity in the last decade. However, this field of dentistry has not been integrated in the dental curriculum at most universities.
According to the method of Kern, a curriculum was designed and established on a voluntary basis in the prosthetic education of a German dental school. The success of the implementation was measured by evaluation carried out by the participants on a visual analogue scale. Furthermore, the clinical performance of the fabricated restorations was evaluated.
Ninety-four percent of all students participated in the CAD/CAM curriculum indicating considerable interest. Nearly half of all students used the acquired knowledge to design crowns for their patients. All restorations fabricated by participants of the new CAD/CAM programme showed good clinical performance.
By phasing-in the CAD/CAM training programme, independent CAD/CAM-based fabrication of all-ceramic crowns increased student's self-confidence in tooth preparation. A tendency was found that students using CAD/CAM technology prepared more teeth than their fellow students who did not use CAD/CAM technology. Further studies are required to investigate the influence of independent CAD/CAM-based single-crown fabrication on the quality of the preparation.
在过去十年中，固定修复体的计算机辅助设计/计算机辅助制造（CAD/CAM）已广受欢迎。然而，在大多数大学的牙科课程中，这一牙科领域尚未得到整合。
根据克恩的方法，在德国一所牙科学校的修复学教育中，自愿设计并建立了一门课程。通过参与者在视觉模拟量表上进行的评估来衡量实施的成功程度。此外，还对制作的修复体的临床性能进行了评估。
94%的学生参加了CAD/CAM课程，表明兴趣浓厚。近一半的学生运用所学知识为患者设计牙冠。新CAD/CAM项目参与者制作的所有修复体均表现出良好的临床性能。
通过逐步引入CAD/CAM培训项目，基于CAD/CAM的全瓷牙冠独立制作增强了学生在牙体预备方面的自信心。发现一种趋势，即使用CAD/CAM技术的学生比未使用该技术的同学预备的牙齿更多。需要进一步研究来调查基于CAD/CAM的单冠独立制作对预备质量的影响。
