聚焦前牙美学区引导骨再生（GBR）术后钛网暴露并发症的预防与微创处理策略。前牙区退缩易致轮廓塌陷与"黑三角"，钛网的高张力特性常引发软组织裂开。本文系统回顾了钛网暴露的病因学及"伪骨膜"的组织学屏障作用，并探讨基于临床分级的氯己定保守去污及外科干预策略。在预防层面，论述改良"雨披"皮瓣等无张力闭合设计的生物力学优势。针对已暴露缺损，评价游离上皮下结缔组织移植完美的美学重塑地位，以及富血小板纤维蛋白结合微创隧道技术的生物刺激潜力。此外，阐述Er：YAG激光去污及细胞相容性重建的前沿协议，并展望3D打印定制钛网、可吸收缝线固定与载铜抗菌钛合金等生物活性材料的应用前景，旨在构建涵盖"形态设计-被动闭合-微创修补-激光去污-活性材料"的跨学科系统化解决方案。

This study focuses on the prevention and minimally invasive management of titanium mesh exposure following guided bone regeneration in the anterior esthetic zone. Anterior tissue recession often causes contour collapse and "black triangles", while the high tension of titanium meshes frequently induces soft tissue dehiscence. The etiology of mesh exposure and the histological barrier role of the "pseudo-periosteum" are systematically reviewed, alongside evidence-based strategies ranging from conservative chlorhexidine decontamination to surgical interventions based on clinical grading. For prevention, the biomechanical advantages of tension-free passive closure designs, such as the modified poncho technique, are highlighted. To address exposed defects, the gold standard status of subepithelial connective tissue grafts for esthetic remodeling and the biostimulation potential of platelet-rich fibrin combined with minimally invasive tunneling are evaluated. Furthermore, cutting-edge protocols for Er: YAG laser decontamination and cytocompatibility restoration are introduced, anticipating the future applications of 3D-printed customized meshes, resorbable suture fixation, and bioactive copper-bearing titanium alloys. The objective is to provide a comprehensive, interdisciplinary solution encompassing morphological design, passive closure, minimally invasive repair, laser decontamination, and bioactive materials.
