환자맞춤형 3D 프린팅 모델을 활용한 매복 사랑니 발치 실습의 교육적 효과: 예비 연구 ; Educational Effects of Surgical Extraction Training Using Patient-customized 3D Printing Model: A Pilot Study

Tooth extraction is a skill that must be competent to provide primary care as a general dentist after graduating from dental college. However, compared to simple extraction, surgical extraction is not only difficult to perform, there is a risk of surgery, and dental students have fewer opportunities to treat patients, making it difficult to be competent. Therefore, we developed a surgical simulation of the impacted third molar extraction course using patient-specific 3D printing model. This study aims to analyze the educational effect of this practice by content analysis of reflection writing of students who actually performed the operation after simulation using a 3D printing model. As a result of content analysis for students’ reflective writing, it was found that surgical simulation using the 3D printing model greatly contributed to the motivation for self-directed learning as well as the improvement of students’ knowledge and skills. In conclusion, through surgical simulation course accompanied by reflection writing, dental students can improve the ability to perform surgical extraction and induce self-directed learning. ; open
