BACKGROUND
Education of undergraduates in implant dentistry has been extended. In order to assess the correct implant position, the accuracy of implant insertion using templates for pilot-drill guided and full-guided implant insertion was examined in a laboratory set-up in a cohort of undergraduates.
METHODS
After three-dimensional planning of the implant position in partially edentulous mandibular models, individual templates for the pilot-drill guided or full-guided implant insertion in the region of the first premolar were produced. A total of 108 dental implants were inserted. The results of the radiographic evaluation of the three-dimensional accuracy were statistically analyzed. Furthermore, the participants completed a questionnaire.
RESULTS
The deviation of the three-dimensional angle of the implants inserted fully guided was 2.74 ± 1.49 degrees compared to 4.59 ± 2.70 degrees for pilot-drill guided. The difference was statistically significant (p < 0.01). The returned questionnaires revealed a high interest in oral implantology and a positive evaluation of the hands-on course.
CONCLUSIONS
In this study, the undergraduates benefited from applying full-guided implant insertion considering the accuracy in this laboratory examination. However, the clinical effects are not clear as the differences are within a small range. Based on the returned questionnaires, the implementation of practical courses in the undergraduate curriculum should be encouraged.
背景
本科生的种植体牙科教育已经得到扩展。为了评估正确的种植体位置，在一个实验室环境中，对使用导板引导的预备孔钻头和全引导种植体插入的模板进行了研究，以检查其在种植体插入中的准确性。
方法
在部分无牙下颌模型中对种植体位置进行三维规划后，为第一前磨牙区域的预备孔钻头引导或全引导种植体插入制作了个体化模板。总共插入了 108 颗牙种植体。对三维精度的放射学评估结果进行了统计学分析。此外，参与者还完成了一份调查问卷。
结果
与预备孔钻头引导相比，全引导插入的种植体三维角度偏差为 2.74 ± 1.49 度。差异具有统计学意义（p < 0.01）。返回的调查问卷显示，学生对口腔种植学有很大的兴趣，并对实践课程给予了积极评价。
结论
在这项研究中，本科生在实验室检查中受益于全引导种植体插入，考虑到其准确性。然而，由于差异在较小范围内，临床效果尚不清楚。根据返回的调查问卷，应该鼓励在本科生课程中实施实践课程。
