帐篷钉技术结合CGF膜修复重度牙槽嵴缺损1例

Tent-pole Technique Combine with CGF for Reconstruction of Serious Bone Defects:A Case Report

本文报道了1例用帐篷钉技术结合浓缩生长因子(CGF)膜引导骨再生并进行延期种植,成功完成上颌后牙区牙槽嵴骨量严重不足的种植修复,最大程度减轻患者术后反应及避免自体骨移植手术带来的痛苦。经过1年随访,种植体各项指标良好,患者对修复体功能表示满意。期望本病例能为重度牙槽嵴缺损的骨增量方案提供新思路。

This article illustrates a successful case for reconstructing severely resorbed maxilla.Tent-pole technique in combination with concentrate growth factor were selected as a modification to general guided bone regeneration procedure.Delayed implant placement was performed in order to avoid the fearing of autogenous bone grafting and the risk factors in lateral window for sinus floor elevation.One-year follow-up visit showed that all implants were stable and prosthesis were satisfactory.It is expected that this case will provide new ideas to the bone regeneration protocol for severe alveolar ridge defects.
