Guided bone regeneration (GBR) is a surgical procedure that utilizes bone grafts with barrier membranes to reconstruct small defects around dental implants. This procedure is commonly deployed on dehiscence or fenestration defects ≥2 mm, and mixing with autogenous bone is recommended on larger defects. Tension-free primary closure is a critical factor to prevent wound dehiscence, which is critical cause of GBR failure. A barrier membrane should be rigidly fixed without mobility. If the barrier is exposed, closed monitoring should be utilized to prevent secondary infection.
引导骨再生（GBR）是一种外科手术，它利用骨移植材料和屏障膜来修复牙种植体周围的小骨缺损。该手术通常用于≥2mm的骨开裂或骨开窗缺损，对于较大的缺损，建议与自体骨混合使用。无张力一期缝合是预防伤口裂开的关键因素，而伤口裂开是GBR失败的关键原因。屏障膜应牢固固定，不能移动。如果屏障膜暴露，应密切监测以防止继发感染。
