What is guided bone regeneration?
Guided bone regeneration (GBR) is a surgical technique using a barrier membrane to direct and stimulate new bone formation at sites where insufficient bone exists for dental implant placement.
When bone loss occurs from tooth extraction, gum disease, or trauma, the jaw may lack the height or width needed to support a dental implant. Guided bone regeneration addresses this shortfall by using a physical barrier (typically a membrane made of collagen, polytetrafluoroethylene, or other biocompatible materials) to create and protect a space at the implant site. This barrier blocks soft tissue from collapsing into the area, allowing bone cells to fill the void and rebuild the structure.
The regenerated bone develops over several months, creating a foundation sturdy enough for implant placement. Practitioners in Greenville, SC offering this technique often pair it with bone grafting material (autogenous, allogeneic, or synthetic) placed beneath the membrane to speed healing and improve density. The technique is particularly valuable when alveolar crest height or width is compromised, as it can mean the difference between a patient qualifying for implants or requiring more invasive surgical alternatives.
Success depends on proper membrane selection, graft placement, and patient healing capacity. After the bone regenerates sufficiently (typically 4 to 9 months), the implant can be placed during a second procedure. For patients considering implants but concerned about bone loss, providers who specialize in oral surgery and implant placement can evaluate whether guided bone regeneration makes implant treatment possible.
