Rehabilitation of segmental defects of maxilla presents a reconstructive challenge to obtain an ideal osseous form and height with adequate soft tissue investment. Though variety of prosthetic and surgical reconstructive options like the use of vascularized and non vascularized bone grafts are available they produce less than optimal results. Bone transport distraction is a reliable procedure in various maxillofacial bony defect reconstruction techniques. We describe herein a technique of maxillary bone transport distraction using an indigenously designed, custom made trifocal transport distractor performed in a post traumatic avulsive defect of the anterior maxilla. Transport distraction was successful for anterior maxillary alveolar bony regeneration, with excellent soft tissue cover and vestibular depth, which also helped close an oroantral/oronasal fistula.
上颌骨节段性缺损的修复对获得理想的骨形态和高度以及足够的软组织覆盖提出了重建挑战。尽管有多种修复和外科重建选择,如使用带血管和不带血管的骨移植,但它们产生的效果并不理想。骨搬运牵张成骨是各种颌面骨缺损重建技术中一种可靠的方法。我们在此描述一种使用自行设计、定制的三焦点骨搬运牵张器进行上颌骨搬运牵张的技术,该技术应用于上颌前部创伤后撕脱性缺损。骨搬运牵张成功实现了上颌前部牙槽骨的再生,伴有良好的软组织覆盖和前庭深度,这也有助于闭合口腔上颌窦/口鼻瘘。
