数字化三维手术模拟结合3D打印在正颌外科专科医师培训中的应用

正颌外科手术复杂，强调理论与实践相结合，教学难度大，受条件限制不能开展有效的实践教学，学生难以掌握手术操作。本文将数字化三维手术模拟和3D打印结合应用于正颌外科专科医师培训，分别在理论知识教学、手术操作教学、总结与反思等教学环节应用数字化软件以及3D打印，将实践教学与理论教学相结合，积极发挥学生的主观能动性。结果显示，实验组教学评价（3.89±0.84）分）]优于对照组（2.91±1.21）分]，数字化三维手术模拟结合3D打印的教学模式取得了满意的效果。

Application of digital three-dimensional surgical simulation system combined with 3D printing in specialist training of orthognathic surgery

The teaching of orthognathic surgery is difficult because it is complex and emphasizes the combination of theory and practice. The traditional teaching method focuses on theoretical teaching, but due to the limitation of conditions, it is difficult for students to master the operation. In this paper, we apply the digital three-dimensional surgical simulation system combined with 3D printing in specialist training of orthognathic surgery. Digital software and 3D printing are applied in the theoretical teaching, surgical operation, summary and reflection to combine practical teaching with theoretical teaching, so as to stimulate the subjective initiative of the students. The results showed that the teaching evaluation of the experimental group (3.89±0.84) points] was better than that of the control group (2.91±1.21) points]. The application of digital three-dimensional surgical simulation system combined with 3D printing has achieved satisfactory results.
