摘要: 目的 探讨CAD/CAM技术联合个性化预成型钛网及游离髂骨移植修复单侧下颌骨大型轮廓缺损的可行性及有效性。方法 选取四川大学华西口腔医院正颌及关节外科2015年11月—2019年12月的15例单侧下颌骨大型轮廓缺损的患者。采用基于逆向工程的计算机辅助设计/计算机辅助制作(CAD/CAM)技术,镜像重建患侧下颌骨轮廓并制作个性化预成型钛网,术中切取游离髂骨联合预制钛网经颌下植入于下颌骨缺损部位,其中2例患者同期行颏成形术矫正颏部偏斜。术后通过测量比较双侧下颌支及下颌体的长度及其三维角度评价下颌骨轮廓的对称性。结果 所有患者预后良好,对手术效果满意且无不良并发症,术后三维测量结果显示下颌骨轮廓对称性良好(P>0.05)。结论 利用CAD/CAM技术制作个性化预成型钛网联合髂骨移植修复单侧下颌骨大型轮廓缺损可行,效果良好。

Abstract: Objective To explore the feasibility and effectiveness of using CAD/CAM combined with individualized titanium mesh and iliac bone graft to repair unilateral large-sized mandibular contour defects. Methods From November 2015 to December 2019, fifteen patients with unilateral large-sized mandibular contour defects were enrolled in this study. Personalized preformed titanium mesh and mandible models were fabricated by computer-aided design/computer-aided manufacture (CAD/CAM) based on reverse engineering to reconstruct mandibular contour defect. Two patients accepted genioplasty to adjust the deflective region. Length of the bilateral mandibular ramus and mandibular body and its three-dimensionality were measured and compared to analyze symmetries of mandibular contour after surgery. Results All patients have satisfactory results and no adverse complications. Measurements showed satisfactory symmetries of mandibular contour in the 3D position after surgery (P>0.05). Conclusion The study suggests that this technique was feasible and efficient for the reconstruction of unilateral large-sized mandibular contour defects.
