Lateral GBR Using Two Types of Membrane With a Combination of Allograft-xenograft

Bone width is critical for successful implant placement, as thin bone increases the risk of bone loss. Various augmentation techniques-especially guided bone regeneration (GBR)-are effective in restoring bone volume using grafts and barrier membranes. Collagen membranes are commonly used but degrade quickly, leading to the development of improved types like porcine peritoneum membranes, which show better strength and durability. While autogenous grafts are the gold standard, combining different graft materials (e.g., xenograft and allograft) has shown promising results. However, no studies have directly compared porcine peritoneum membranes with cross-linked membranes using such graft combinations. This study aims to evaluate and compare their effectiveness in increasing bone width.
