Patients with significant craniofacial asymmetry may have functional problems associated with their occlusion and aesthetic concerns related to the imbalance in soft and hard tissue profiles. This report details a case of facial asymmetry secondary to left mandible angle deficiency due to undergoing previous radiotherapy. We describe the correction of the bony deformity using computer aided design/computer aided manufacturing custom-made titanium onlay using novel direct metal laser sintering. The direct metal laser sintering onlay proved a very accurate operative fit and showed a good aesthetic correction of the bony defect with no reported complications postoperatively. It is a useful low-morbidity technique, and there is no resorption or associated donor-site complications.
严重颅面部不对称的患者可能存在与咬合相关的功能问题以及与软硬组织轮廓失衡相关的美学问题。本报告详细介绍了一例因先前接受放射治疗导致左下颌角发育不全继发面部不对称的病例。我们描述了使用计算机辅助设计/计算机辅助制造的定制钛覆盖物，通过新型直接金属激光烧结技术来矫正骨畸形。直接金属激光烧结覆盖物在手术中显示出非常精确的贴合度，对骨缺损有良好的美学矫正效果，术后未报告并发症。这是一种有用的低发病率技术，不存在吸收或相关供区并发症。
