研究目的:

本研究旨在通过对已完成的临床病例资料进行系统分析,评估钛膜钉骨内锚定技术辅助下的改良型根向复位瓣联合游离龈移植术在种植患者角化龈增量中的应用效果。研究重点在于回顾性分析该技术体系在解决传统缝合技术所面临的稳定性不足、操作复杂等问题方面的实际表现。  

Objectives of Study:

This study aims to evaluate, through a systematic analysis of completed clinical cases, the effectiveness of a modified apically repositioned flap combined with free gingival graft for keratinized gingiva augmentation in implant patients, with the assistance of intraosseous anchorage using titanium membrane tacks. The focus of this retrospective study is to assess the practical performance of this technique in overcoming the limitations of conventional suturing methods, particularly insufficient stability and procedural complexity.
