Prosthetic total temporomandibular joint (TMJ) replacement (TJR) is well established in the United Kingdom, with clear guidelines for indications and nationally published outcomes. CAD/CAM technology has made it possible to push the boundaries of custom-made TJR to include extended versions (eTJR), which may replace segmental mandibular defects or defects in the skull base with extended components for the ramus and fossa, respectively. Such prostheses are uncommon, and published reports are restricted to isolated cases and series of cases. We know of no previous attempts to classify such prostheses, and here we suggest a bipartite classification system for use in communications between surgeons and manufacturers based on a review of 19 prostheses provided by one manufacturer (TMJ Concepts, Ventura, CA).
人工全颞下颌关节（TMJ）置换术（TJR）在英国已得到广泛应用，有明确的适应症指南和全国公布的治疗结果。计算机辅助设计/计算机辅助制造（CAD/CAM）技术使得定制TJR的范围得以拓展，包括扩展型TJR（eTJR），它可以分别用用于下颌支和颞窝的扩展部件来替代节段性下颌骨缺损或颅底缺损。这类假体并不常见，已发表的报告仅限于个别病例和病例系列。我们之前不知道有对这类假体进行分类的尝试，在此，我们基于对一家制造商（加利福尼亚州文图拉市的TMJ Concepts公司）提供的19个假体的回顾，提出一种二分法分类系统，供外科医生和制造商之间交流使用。
