研究目的:

种植修复已成为缺失牙修复的主要手段,对于骨量不足的种植位点,引导骨再生(Guided Bone Regeneration, GBR)是处理骨缺损的重要方法。在GBR手术操作过程中,是否需要在受体床进行去皮质(decortication)一直存在争议。研究旨在明确去皮质操作在下颌后牙区等高密度皮质骨区域是否真正带来额外获益,为临床医生提供循证依据,帮助优化GBR手术流程,避免不必要的创伤和风险。  

Objectives of Study:

Dental implant–supported restoration has become the primary treatment modality for the rehabilitation of missing teeth. For implant sites with insufficient bone volume, guided bone regeneration (GBR) is a well-established approach for managing alveolar bone defects. During GBR procedures, whether decortication of the recipient bed is necessary remains controversial. This study aims to clarify whether decortication provides additional clinical benefits in high-density cortical bone regions, such as the posterior mandible, thereby providing evidence-based guidance for clinicians to optimize GBR protocols and to avoid unnecessary surgical trauma and potential risks.
