Application of CAD/CAM Technology in the Teaching of Inlay Production
-
摘要:
目的 研究在嵌体制作教学中,CAD/CAM技术的应用价值。 方法 以在昆明医科大学附属延安医院口腔科实习的60名本科生为研究对象,随机分为实验组(n=30)和对照组(n=30);选择合适的临床病例让学生进行下颌磨牙邻面嵌体牙体预备,指导教师通过不同的方式对第1次预备结果进行指导,由学生进行2次修改预备,考核小组对最终预备体的预备量、预备体外形、面洞形、鸠尾固位型、邻面洞形5个方面进行打分评价。 结果 实验组各项检测指标分值均高于对照组(P<0.05)。 结论 CAD/CAM技术应用于嵌体制作教学中可有效提高学生临床动手能力,达到较传统教学方式更好的教学效果。 -

Abstract:Objective To study the application value of CAD/CAM technology in the teaching of inlay manufacturing. Methods A total of 60 undergraduates interned in the Department of Stomatology, Yan’ an Hospital, Kunming Medical University were randomly divided into an experimental group (n=30) and a control group (n=30). We selected appropriate clinical cases for students to prepare for mandibular molar’ s proximal occlusal inlays. The instructor guided the results of the first preparation in different ways, and the students made the second modification and preparation, and the assessment team scored and evaluated the five aspects of the final preparation, the shape of the preparation, the shape of the occlusal surface, the dovetail retention, and the adjacent surface. Results The scores of all detection indexes in the experimental group were higher than those in the control group (P<0.05). Conclusion The application of CAD/CAM technology in inlay manufacturing teaching can effectively improve students' clinical hands-on ability and achieve better teaching effects than traditional teaching methods. -
