Orthognathic surgery addresses skeletal dysgnathias, enhancing both function and aesthetics. Despite its benefits, potential complications underscore the need for well-trained surgeons. 3D-printed anatomical models, a product of additive manufacturing, aid surgical education, especially for young surgeons lacking on-the-job training. This study focuses on an economically designed 3D-printed simulator for orthognathic surgery training.
Evaluation from 31 participants of two orthognatic surgery workshops using the 3D-printed simulator highlighted positive assessments for realism (7.16 ± 2.03/10) and usefulness in training for specific procedures. While commended for simulating limited oral cavity movements and providing a realistic general simulation, soft tissue realism (4.51 ± 2.66/10) suggested room for improvement. Notably, the simulator demonstrated outstanding cost-efficiency (€ 181.55), with reusable components.
The 3D-printed simulator offers a realistic, cost-effective tool for orthognathic surgery training, despite soft tissue realism limitations. The study anticipates further enhancements in 3D-printing technology to address these aspects and advance future iterations.
正颌外科手术用于解决骨骼性牙颌面畸形问题，可同时改善功能和美观。尽管有诸多益处，但潜在并发症凸显了训练有素的外科医生的必要性。3D打印解剖模型作为增材制造的产物，有助于外科手术教育，尤其对于缺乏在职培训的年轻外科医生。本研究聚焦于一种经济设计的用于正颌外科手术训练的3D打印模拟器。
来自两个正颌外科手术工作坊的31名参与者对使用该3D打印模拟器进行的评估显示，对其逼真度（7.16±2.03/10）以及在特定手术训练中的实用性给予了积极评价。虽然该模拟器因模拟有限的口腔运动和提供逼真的总体模拟而受到称赞，但软组织逼真度（4.51±2.66/10）表明仍有改进空间。值得注意的是，该模拟器展示出卓越的成本效益（181.55欧元），且组件可重复使用。
尽管存在软组织逼真度方面的局限性，但该3D打印模拟器为正颌外科手术训练提供了一种逼真且经济高效的工具。该研究预计3D打印技术将进一步改进以解决这些问题并推动未来迭代发展。
