A mandibular continuity defect can be repaired using either a prosthetic device or autogenous bone. A titanium reconstruction plate can be used with a localized or vascularized flap over the defect of the mandible. Unfortunately, the plate may fail due to plate exposure, screw loosening, fracture, or infection, and will need to be removed. Plate exposure though the skin or mucosa is one of the main reasons for failure. In the present work, the authors introduced a lingually positioned reconstruction plate fabricated via three-dimensional printed bending support. This custom reconstruction plate can avoid plate re-exposure as well as reduce surgical errors and operation time.
下颌连续性缺损可使用假体装置或自体骨进行修复。钛重建板可与局部或带血管蒂皮瓣一起用于下颌骨缺损处。不幸的是,该钢板可能会因钢板外露、螺钉松动、骨折或感染而失效,需要取出。钢板通过皮肤或黏膜外露是失败的主要原因之一。在本研究中,作者介绍了一种通过三维打印弯曲支架制造的舌侧定位重建板。这种定制的重建板可以避免钢板再次外露,同时减少手术误差和手术时间。
