Premaxillary tooth loss and bone deficiency or atrophy often occur in facial trauma. Onlay bone graft and implants have so far been the best means of restoring function and esthetic appearance. Void space between the graft and the jaw bone, over projection and mucosal trauma can cause mucosal dehiscence, bone exposure, or resorption and can compromise implant survival. Virtual surgical planning using 3-dimensional printing technology has improved the efficiency of craniofacial surgery. The drawbacks of this technology are its cost and time-consuming preparation. However, the democratization of high-performance 3-dimensional printing and open-source software have enabled surgeons to master the procedure. The authors applied this innovative technology to customize bone graft for insertion of a premaxillary implant. It enabled us to custom-make the bone graft on the template and to perfectly embed the graft in the gap with a reduce operating time and a good osteointegration.
前上颌骨牙齿缺失以及骨缺损或萎缩常在面部创伤中出现。目前，骨增量移植术和植入物是恢复功能和美观的最佳手段。移植骨与颌骨之间的空隙、过度突出以及黏膜创伤可导致黏膜裂开、骨暴露或吸收，并可能影响植入物的存活。使用三维打印技术的虚拟手术规划提高了颅面外科手术的效率。该技术的缺点是成本高且准备工作耗时。然而，高性能三维打印和开源软件的普及使外科医生能够掌握这一操作。作者应用这项创新技术定制骨移植以植入前上颌种植体。它使我们能够在模板上定制骨移植，并将移植骨完美地嵌入间隙中，同时缩短了手术时间并实现了良好的骨整合。
