Exposure of d-PTFE membrane: remove or leave as is?

Last Updated November 22, 2016

I have a case where I needed to perform ridge augmentation. The bone graft was covered with d-PTFE membrane and stabilized with screws. Primary closure was achieved with mattress and single sutures. Some weeks after suture removal, the membrane became exposed. I know d-PTFE membrane can be left exposed, but it’s also recommended that the membrane be removed at around 4 weeks. My question is: In my case do I try to remove the membrane or just leave it as is? My concern is that the exposure is going to widen and soft tissue will not grow over the membrane. If I do need to remove the membrane, do I flap the gum again to remove the screws and the membrane?
