Analyzing guided bone regeneration methods: A review of the literature

Abstract

Guided bone regeneration (GBR) is a surgical technique involving bone grafts and barrier membranes to repair minor defects near dental implants. It is typically used for dehiscence or fenestration defects ≥2 mm, often incorporating autogenous bone for larger defects. Achieving tension-free primary closure is essential to avoid wound dehiscence, a leading cause of GBR failure. Proper fixation of the barrier membrane without mobility is crucial. Continuous monitoring is necessary if the membrane becomes exposed to prevent secondary infections
