三维数字化模型在牙体缺损修复方案设计教学中的应用效果研究
Application of three-dimensional digital model in clinical teaching of prosthodontics
摘要
Abstract
Objective To evaluate the effect of three-dimensional digital model in the clinical teaching of prosthodon-tics.Methods This study was conducted in May 2023 in Guanghua School of Stomatology,Sun Yat-sen University.For-ty undergraduate students majoring in clinical oral medicine in Guanghua School of Stomatology,Sun Yat-sen University in 2019 were selected as the research subjects and were randomly divided into the study group and the control group,with 20 students in each group.Data from 100 cases in the database were randomly selected.The restoration types of 100 cases were determined by three experts as the evaluation criteria.The above cases were randomly divided into teaching group and assessment group,with 50 cases in each group.The students in the study group were trained by digital three-dimensional model,and completed the case study of the teaching group by using three-dimensional software,and then judged and selected the restoration types of the cases in the assessment group.Students in the control group used two-di-mensional pictures as case materials for learning and subsequent case assessment.After comparison with the expert stan-dard,the accuracy of the two groups of students in judging the types of restorations was calculated.A questionnaire sur-vey was conducted on the teaching effect of the two groups.Results In terms of the judgment of onlay and post-core crown,the accuracy of the study group was higher than that of the control group,and the differences were statisti-cally significant(all P＜0.001).The results of the ques-tionnaire survey showed that the students in the study group scored higher than those in the control group in terms of interest in learning,understanding of theoretical knowledge,perception of tooth defect,confidence in the choice of prosthesis type and efficiency,and the differences were statistically significant(all P＜0.05).Conclusion The appli-cation of 3D digital model in clinical teaching of prosthodontics is helpful for students to deeply understand the knowl-edge system of fixed restoration of tooth defect,and helps them complete the cognitive transformation from theoretical learning to clinical practice.关键词
