Guided Gum Tissue Regeneration

California rates for HCPCS D4266

A gum surgery technique that places a thin, dissolvable membrane over an area of bone loss to keep gum tissue from growing into the space too quickly, giving bone and the fibers that anchor the tooth a chance to regrow first. The membrane breaks down on its own over time, so it does not need a separate removal visit.
