动态导航引导下下颌骨缺损腓骨瓣移植修复区种植体植入1例报告

Dental implant placement by means of dynamic navigation following free fibula flap reconstruction for mandibular defect:a case report

腓骨瓣移植修复下颌骨缺损后常采用种植义齿修复缺牙。由于腓骨的截面类似三角形、恢复的骨高度不足及内固定钛钉钛板的存在,以修复为导向在移植腓骨上进行种植体植入成为口腔种植领域的难题。本文对1例腓骨瓣移植修复下颌骨缺损患者在动态导航引导下,在移植腓骨上精准植入4颗种植体以恢复缺牙和咀嚼功能,取得了理想效果。

Dental implant rehabilitation could be considered in patients reconstructed with free fibula flap for mandibular defect.Prosthetically driven implant placement in free fibula flap represents a challenge for the cross triangle section of the fibula,the insufficient bone height and the existence of the internal fixed titanium screw and plate.This paper reported one case reconstructed with free fibula flap for mandibular defect and 4 implants placed in the fibula by means of dynamic navigation,with recovery missing teeth and chewing function.
