Titanium Reinforced d-PTFE Membrane Versus Collagen Membrane For Guided Bone Regeneration

A mucoperiosteal flap will be raised with two vertical releasing on each side of the edentulous space. Autogenous bone chips are harvested from the retromolar area with bone scrapers and/or from an edentulous site using ACM bone collector. DBBM particles soaked in blood are mixed with autogenous bone chips to a ratio of 1:1. After having made multiple bone perforations at the buccal aspect of the recipient site, the mixture of bone chips and DBBM is applied. An individualized collagen membrane is attached on top using membrane fixation pins. Prior to fixation of the final pin, bone grafting material is additionally applied from the lateral aspect to ensure that it is properly packed under the membrane and fully stable. Following release of the periosteum and muscle insertion, tension-free primary wound closure is achieved.

Care is taken to leave a distance of at least 1 mm between the membrane and neighboring teeth. Prior to fixation of the final pin, bone grafting material is additionally applied from the lateral aspect to ensure that it is properly packed under the membrane and fully stable. Following release of the periosteum and muscle insertion, tension-free primary wound closure is achieved. The membrane is removed after 9 months, prior to implant placement.
