PURPOSE
The mandible is an essential esthetic and functional component of the lower third of the face and its reconstruction has always been a challenge, especially after severe post-traumatic injuries. The purpose of the present report was to introduce a new approach of mandibular reconstruction in a patient who had lost the entire mandible except for the rami after being severely injured in a blast.
MATERIALS AND METHODS
A new approach using a titanium mandibular rami implant technique was applied using computer-aided 3-dimensional virtual planning and rapid prototyping technology. A prosthetic component was supported by the mandibular implant, which achieved occlusion and dedicated function for the patient.
RESULTS
This method offered precise adaptation of the implant and prosthesis and an easier surgical procedure, providing a shortened operation time, no donor site morbidity, and more predictable outcomes.
CONCLUSION
This new technique allows reconstruction of large-scale mandibular defects that is not possible by conventional surgical methods.
目的
下颌骨是面部下三分之一重要的美学和功能组成部分，其重建一直是一项挑战，尤其是在严重创伤后。本报告的目的是介绍一种下颌骨重建的新方法，该方法应用于一名在爆炸中严重受伤后除下颌支外整个下颌骨缺失的患者。
材料与方法
采用计算机辅助三维虚拟规划和快速成型技术，应用钛质下颌支种植体技术的新方法。下颌种植体支撑一个修复部件，为患者实现咬合和特定功能。
结果
该方法使种植体和假体精确适配，手术过程更简便，缩短了手术时间，无供区并发症，且结果更可预测。
结论
这项新技术能够重建传统手术方法无法实现的大面积下颌骨缺损。
