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.
