颌骨缺损血管化游离骨瓣重建后的种植修复治疗

Dental implant treatment in vascularized bone flaps after jaw reconstruction

因为肿瘤等原因造成的颌骨缺损,常严重影响外形和功能。口腔颌面部肿瘤治疗的目标除了治愈肿瘤,还应该包括尽量恢复患者患病前的功能。显微外科技术和数字化外科技术的发展推动了以血管化游离骨瓣重建颌骨缺损的发展,术前的可视化设计可以帮助获得更好的外形。在重建的颌骨上如何恢复咬合功能,提高患者的生活质量,成为一个重要的研究方向。本文将从颌骨重建理念、血管化骨瓣的选择、种植时机的选择、种植体周围软组织的处理、放疗对颌骨重建后种植义齿的影响等方面进行讨论。

Jaw defects caused by various reasons often seriously affect appearance and function.The goal of the treatment of oral and maxillofacial tumors should include the cure of the tumor and the restoration of premorbid function.The development of microsurgery and digital surgery technology has promoted the development of jaw reconstruction with vascularized free bone flap.Good appearance and improved predictability could be obtained with the help of preoperative visual design.How to rehabilitate occlusal function on the reconstructed jaw and improve the quality of life of patients has become an important research direction.This article discusses the challenge of jaw reconstruction,the selection of vascularized bone flap,the choice of implant timing,the treatment of peri-implant soft tissue,and the influence of radiotherapy on implants after jaw reconstruction.
