The diagnosis and treatment of facial deformities, including mandibular asymmetries, can pose a significant clinical problem. The limitations, accuracy and predictability of treatment options available and the expectations of the patient can further compound this. In this article we present a case of facial asymmetry secondary to mandibular angle deficiency corrected by the manufacture and placement of a custom-made titanium onlay. Although alternative methods were potentially available to correct this deformity, patient factors including occlusion, dental/skeletal relationship and chin position limited our options. Furthermore, construction of the custom-made titanium onlay involved the development of a computer-generated 3D virtual model and computer-aided design and computer-aided manufacture (CAD-CAM) of the inlay. This report demonstrates that this technique can be used successfully to address certain cases of facial asymmetry.
面部畸形的诊断和治疗，包括下颌不对称，可能会带来重大的临床问题。现有治疗方案的局限性、准确性和可预测性以及患者的期望会使这一问题更加复杂。在本文中，我们介绍了一例因下颌角缺损继发的面部不对称病例，通过制作和植入定制钛质嵌体进行了矫正。尽管可能有其他方法来矫正这种畸形，但包括咬合、牙/骨关系和下巴位置等患者因素限制了我们的选择。此外，定制钛质嵌体的制作涉及计算机生成的3D虚拟模型的开发以及嵌体的计算机辅助设计和计算机辅助制造（CAD-CAM）。本报告表明，该技术可成功用于解决某些面部不对称病例。
