研究目的: |
本研究拟开展前瞻性、随机、对照、单盲临床研究,比较传统“填骨+覆膜”方法与“单纯填骨、不覆膜”改良方案在二壁骨缺损拔牙位点中的疗效差异,主要目标是验证无膜方案在骨量保持与软组织愈合等方面是否不劣于常规覆膜方案。 |

Objectives of Study: |
This study aims to conduct a prospective, randomized, controlled, single-blind clinical trial to compare the efficacy of the conventional “bone grafting with membrane coverage” approach and the modified “bone grafting without membrane coverage” protocol in extraction sites with two-wall bone defects. The primary objective is to determine whether the membrane-free approach is non-inferior to the conventional membrane-covered technique in terms of bone volume preservation and soft tissue healing. |
