The goal of this clinical study was to evaluate the effect of the periosteal pocket flap in horizontal GBR.

Methods:
22 patients with a mean ridge width of 2.94 mm were treated by GBR using a periosteal envelope flap according to the protocol by Steigmann et al. Following detachment of the periosteum from the bone, a pocket was created to accommodate the bone grafting material (cerabone®) and barrier membrane (Jason® membrane). The periosteum was sutured to the membrane and the flap was closed tension-free. Ridge width was measured prior augmentation and 4 to 6 months post-surgery using CBCT.

Results:
Healing was uneventful for all treated patients. A statistically significant mean gain in ridge width of 2.53 mm was achieved 4 to 6 months post-operative allowing for the placement of dental implants.

Conclusions:
The authors concluded that the periosteal pocket flap in conjunction with GBR, using Jason® membrane and cerabone®, is a suitable technique to increase the width of the alveolar ridge.
