Application of 3D printing technology in clinical teaching about jaw bones tumor and tumor-like lesions
Abstract
Objective To explore the effect of 3D printing technology applying into clinical teaching about jaw bones tumor and tumor-like lesions. Methods In order to proceed the contrastive teaching experiment, we divided 92 students who participated in the jaw bones tumor and tumor-like lesions class into 2 groups randomly. Students in group 1 took traditional teaching method including the basics of knowledge, case analysis and CBCT test at the first period. After that, they took new teaching method assisted by 3D printing technology at the second period. Students in group 2 were taught in reverse order by the same teacher. The questionnaire survey was conducted after each period in each group so as to evaluate the role new teaching method assisted by 3D printing technology played in the jaw bones tumor and tumor-like lesions clinical teaching. Results The questionnaire surveys showed that traditional teaching method predominated in the students' grasp of basic knowledge about jaw bones tumor and tumor-like lesions(P＜0.05). With regard to showing the details and spatial forms of lesions as well as teaching vividly, new teaching method assisted by 3D printing technology was better than the traditional one(P＜0.05).The order didn't concern a lot about the final learning effectiveness. However, when it came to the memorizing of knowledge and the understanding of lesions' spatial forms, students who took the new teaching method first had higher average scores(P＜0.05). Conclusions To some extent, carrying on new teaching method assisted by 3D printing technology first among the class may leads students to a better understanding and mastering about the anatomic features of jaw bones tumor and tumor-like lesions.
