Background: The loss in hard tissue volume may impair proper implant placement. Guided bone regeneration (GBR) has been used to regenerate the lost alveolar ridge prior to or at the same time of dental implant placement. The most important factor for GBR success is graft stability. The periosteal mattress suture stabilizing technique (PMS) is an alternative to pins and screws to stabilize bone grafting material and has the advantage of not requiring the removal of the fixing devices. This retrospective observational study sought to quantify the buccal bone thickness, bone graft area and perimeter following GBR using stabilizing periosteal sutures. Methods: Cone-beam computed tomography (CBCT) were acquired before and 6-months after surgery from 6 patients who undergone GBR with PMS stabilizing technique. Images were analyzed for buccal bone thickness, area, and perimeter. Results: The mean change of buccal bone thickness was 3.42 mm (± 1.31 SD) and proved significant (P=0,005). The mean change of bone crest area proved statistically significant (P=0,001). No significant difference was found in perimeter (p=0,12). Conclusion: PMS delivered desired results without clinical complications. This study shows the potential of this technique as an alternative to pins or screws for graft stabilization in the maxillary esthetic zone.
