Abstract
Purpose: Implant dentistry is an established therapy option with sufficient long-term success for the replacement of missing teeth. Education in implant dentistry should not only focus on theory but also on practical courses. The purpose of the current examination was to assess the accuracy of fully guided and pilot-drill guided implant insertion applying plotted static guides in a cohort of undergraduate dental students.
Methods: Matching a three-dimensional set of radiographic data and surface scans of 51 artificial mandibular models, 51 surgical templates were produced by plotting. Metal sleeves allowing either a pilot-drill or fully guided implant insertion were inserted alternatively in region 36 and 46. A total of 102 implants were inserted by 51 undergraduates. Subsequently, the positions of the implants were analyzed radiographically considering the accuracy. Additionally, the time required for implant insertion was recorded and a questionnaire was completed. Statistical analysis followed.
Results: In general, the accuracy of fully guided implant insertion was higher compared to pilot-drill guided. Mean three-dimensional deviation was 2.24 ± 0.38 degrees for fully guided vs. 4.51 ± 2.20 degrees for pilot-drill guided implant insertion. Time required for fully guided implant insertion was statistically significant higher compared to pilot-drill guided (15:22 ± 5:22 vs. 9:35 ± 3:58 min, p < 0.01). The returned questionnaires reported a high interest but a self-assessed minor previous knowledge in implant dentistry.
Conclusion: The examination could show that inexperienced undergraduates benefited from fully guided implant insertion in a laboratory set-up. Based on the questionnaires there is a distinct demand for an extended education in implant dentistry among undergraduate students.
目的：种植牙是一种成熟的治疗选择，具有足够的长期成功替代缺失的牙齿。种植牙的教育不仅要注重理论教育，而且要注重实践教育。本研究的目的是评估全引导和导钻引导种植体插入的准确性，并在一组牙科本科生中应用绘制的静态引导。方法：将51个人工下颌模型的三维x线数据与表面扫描数据进行匹配，绘制出51个手术模板。金属套管可用于导钻或完全导向植入，可在36区和46区交替植入。51名大学生共植入102颗种植体。随后，考虑准确性，对植入物的位置进行放射学分析。此外，记录植入所需的时间并完成问卷调查。随后进行统计分析。结果：一般情况下，完全引导下种植体插入的准确性高于导钻引导。完全引导的平均三维偏差为2.24±0.38度，而导钻引导的平均三维偏差为4.51±2.20度。与导钻引导相比，完全引导种植体插入所需的时间（15:22±5:22 vs. 9:35±3:58）具有统计学意义上的显著性差异。结论：该研究表明，在实验室装置中，没有经验的大学生可以从完全引导种植体插入中获益。根据调查问卷，有一个明显的需求，在种植牙科扩展教育的本科生。
期刊介绍：
The International Journal of Implant Dentistry is a peer-reviewed open access journal published under the SpringerOpen brand. The journal is dedicated to promoting the exchange and discussion of all research areas relevant to implant dentistry in the form of systematic literature or invited reviews, prospective and retrospective clinical studies, clinical case reports, basic laboratory and animal research, and articles on material research and engineering.
