Abstract

Introduction: We present the reconstruction of the temporomandibular joint (TMJ) with Walter-Lorenz prosthesis (Zimmer Biomet Inc., Biomet Microfixation, Jacksonville, FL) performing 3D virtual surgical planning and cutting guides with computer-aided-manufacturing technology (CAD / CAM). Clinical case: A 66-year-old female patient who had a history of multiple TMJ surgeries complained of functional worsening and pain in the left TMJ, with Walter-Lorenz prosthesis in the right TMJ. Intervention was performed to place another Walter-Lorenz prosthesis in the left TMJ with virtual 3D surgical planning of the osteotomies of the fossa and the ramus, and surgical guides fabricated with CAD/CAM technology. Surgery was carried out according to surgical planning. In the subsequent revisions, the mouth opening was stable and the pain was reduced. Conclusion: TMJ reconstruction with 3D virtual surgical planning of Walter-Lorenz stock prosthesis allows to increase the precision in its placement and simplify the surgical intervention.

Walter-Lorenz型假体颞下颌关节重建的虚拟手术规划。

介绍:我们介绍用Walter-Lorenz假体(Zimmer Biomet Inc.， Biomet Microfixation, Jacksonville, FL)重建颞下颌关节(TMJ)，使用计算机辅助制造技术(CAD / CAM)进行3D虚拟手术计划和切割引导。临床病例:66岁女性患者，有多次TMJ手术史，主诉左侧TMJ功能恶化，疼痛，右侧TMJ采用Walter-Lorenz假体。通过虚拟3D手术计划进行干预，在左侧TMJ放置另一个Walter-Lorenz假体，并使用CAD/CAM技术制作手术指南。手术按照手术计划进行。在随后的修正中，开口稳定，疼痛减轻。结论:采用Walter-Lorenz假体三维虚拟手术计划重建TMJ可提高其放置精度，简化手术干预。
