GBR , guide bone regeneration for implants. I posted this case a couple of month ago explaining how bone graft does in our clinic. This lady came in to remove old implants which was broken. We removed old implants without surgery( minimally invasive way ) and did bone graft with Titanium membrane to enhance bone regeneration on defect site. She came back for check up today. We can see more than enough bone for her next implants.
