Guided Bone Regeneration Combined With PRGF for Atrophic Edentulous Maxilla

This prospective interventional clinical study evaluated guided bone regeneration combined with plasma rich in growth factors for vertical and horizontal augmentation of the atrophic edentulous maxilla. Participants with severe maxillary ridge atrophy requiring bone augmentation before implant-supported rehabilitation underwent guided bone regeneration using a composite graft of autogenous bone and anorganic bovine bone mineral combined with plasma rich in growth factors. Barrier membranes were stabilised with titanium pins, and lateral-window sinus floor elevation was performed when indicated. Implants were placed using a delayed protocol at re-entry after 6-9 months. Radiographic bone height and width were assessed by cone-beam computed tomography before surgery, immediately after surgery, at 6-9 months, and at 12 months. The study also recorded graft dimensional stability, implant placement, and surgical or postoperative complications.

Titanium-Reinforced PTFE Membranes for Bone Augmentation

This prospective comparative clinical study evaluated vertical and horizontal bone gain after guided bone regeneration using titanium-reinforced dense PTFE (TiR-dPTFE) membranes versus reinforced PTFE mesh (RPM) in patients requiring ridge augmentation prior to implant placement. Radiographic outcomes were assessed using CBCT at baseline, 9 months, and 12 months. Histological evaluation was performed in selected cases. Healing events and complications were recorded.
