After an extraction, is a flap and membrane necessary when placing a bone graft, or will a collagen wound dressing such as NeoPlug be sufficient?
Can Neoplug replace a membrane when using a flap procedure?
Many articles have discussed the use of a collagen plug, such as NeoPlug, during ridge preservation procedures. The authors conclude that sufficient short term coverage and protection is achieved provided that there is sufficient thickness and quality of the buccal bone. Extraction sockets with good quality bony walls (typically referred to as a 5 walled socket) show the best results for collagen plug use.
As soon as any bony wall is compromised (thin or missing), then a membrane is recommended for long term protection and containment of the graft material such as Raptos Allograft particulates.
