BACKGROUND
Immediate mandibular reconstruction was performed using a patient-specific titanium mesh tray fabricated by electron beam melting (EBM) /rapid prototyping techniques.
METHODS
Patient-specific titanium trays were virtually designed and fabricated using EBM technology/rapid prototyping for patients requiring mandibular resection and immediate reconstruction using an iliac crest bone graft. Dental implants were placed in the grafted sites and the patients received prosthetic rehabilitation with a follow-up of one year. Clinical data, postoperative bone formation and complications were evaluated.
RESULTS
A symmetric appearance of facial contours was achieved. The titanium tray incorporated the particulate iliac crest bone graft that provided significant bone formation (mean 18.97 ± 1.45 mm) and predictable results. Stability of the dental implants was achieved.
CONCLUSION
The patient-specific titanium meshes and immediate particulate autogenous bone graft showed satisfactory clinical and surgical results in improving patients' quality of life and decreasing the overall treatment time with adequate functional rehabilitation.
背景
采用电子束熔炼（EBM）/快速成型技术制作的定制钛网托盘进行即刻下颌骨重建。
方法
对于需要下颌骨切除并即刻采用髂嵴骨移植进行重建的患者，使用EBM技术/快速成型技术进行定制钛托盘的虚拟设计和制作。在移植部位植入牙种植体，患者接受修复康复治疗，随访一年。评估临床数据、术后骨形成情况及并发症。
结果
实现了面部轮廓的对称外观。钛托盘结合了颗粒状髂嵴骨移植，实现了显著的骨形成（平均18.97±1.45毫米）且结果可预测。牙种植体实现了稳定。
结论
定制钛网和即刻颗粒状自体骨移植在改善患者生活质量、减少总体治疗时间并实现充分功能康复方面显示出令人满意的临床和手术效果。
