仿真颌骨模型结合牙种植手术导板在口腔种植教学中的应用

摘要

Objective To establish a method of making emulational jaw models as assistant tools in implant dentistry education.Methods Emulational jaw models were fabricated by 3D printing technology.After traditional teaching methods,emulational jaw models were used to help students make diagnosis,design operation and simulate operation.Surgical templates then were also fabricated on the emulational jaw models,which would guide the implant insertion surgery more precisely and safely. Results All of the students thought that emulational jaw models could display the morphology of jaw bone more intuitively than CT.Generally,after two to five simulation exercises on the 3D models,young doctors could finally insert implants in a satisfactory position.Conclusion We can make emulational jaw models with 3D printing technology,which can help students achieve the leap from preclinical teaching to clinical practice more smoothly.Therefore,it has promising future in teaching.%目的：探索建立制作仿真颌骨模型的方法，为口腔种植的临床教学提供帮助。方法通过3D 打印技术打印仿真颌骨模型。在对学生进行传统模式教学之后，利用仿真颌骨模型进一步开展种植教学，让学生在该模型上进行诊断、手术设计及预手术练习，并制作手术导板。结果100％的学生认为对患者真实骨情况的展示，仿真颌骨模型比 CT 图像更直观。学生需要在仿真颌骨模型上进行2～5次预手术练习方能找到满意的种植位置。结论通过应用3D 打印技术，可以制作仿真颌骨模型，结合手术导板可帮助医学生完成从理论学习到实际操作的跨越，具有较好的教学前景。
