Abstract：
OBJECTIVE: The reconstruction of mandibular defects poses many difficulties due to the unique, complex shape of the mandible and the temporomandibular joints. With development of microvascular anastomosis, free tissue transplantation techniques, such as deep circumflex iliac artery (DCIA) flap and fibular free flap (FFF), were developed. The DCIA offers good quality and quantity of bone tissue for mandibular segmental defect and implant for dental rehabilitation. Virtual surgical planning (VSP) and stereolithography-guided osteotomy are currently successfully applied in three-dimensional mandibular reconstruction, but most use FFF. There are only a few articles on reconstruction with the DCIA that assess the postoperative results.
METHODS: Three patients admitted during a five month period (April of 2013 to August of 2013) underwent resection of mandible and DCIA musculo-osseous reconstruction using a VSP and stereolithographic modeling and assessment of outcomes included technical accuracy, esthetic contour, and functional outcomes.
RESULTS: This technique yielded iliac bone segment with excellent apposition and duplication of the preoperative plan. Flap survival was 100 percent and all patients maintained preoperative occlusion and contour.
CONCLUSIONS: Based on our experience, we offer considerations and logically consistent protocols by classification of mandibular defects, and demonstrate the benefits in VSP and stereolithographic modeling of mandibular reconstructive surgery with DCIA flap.

摘要：
目的：下颌骨缺损的重建存在许多困难，下颌骨和颞下颌关节的复杂形状。随着微血管吻合术的发展，游离组织移植技术,如旋髂深动脉（DCIA）皮瓣和腓骨游离皮瓣（FFF），是开发的。DCIA为下颌节段性缺损和牙科修复植入物提供了良好的质量和数量的骨组织。虚拟手术计划(VSP)和立体光刻引导截骨术目前已成功应用于下颌骨三维重建,但大多数使用FFF。只有少数关于DCIA重建的文章评估了术后结果。
方法：在5个月期间（2013年4月至2013年8月）收治的3例患者接受了下颌骨切除和DCIA肌肉骨重建，使用VSP和立体光刻建模，结果评估包括技术准确性，审美轮廓，和功能结果。
结果：该技术产生的髂骨段具有良好的并置和重复术前计划。皮瓣生存率为100％，所有患者均保持术前闭塞和轮廓。
结论：根据我们的经验，我们通过下颌缺损的分类提供考虑因素和逻辑上一致的方案，并证明了DCIA皮瓣在VSP和下颌骨重建手术的立体光刻建模中的优势。
