Three-Dimensional Reconstruction of Atrophic Posterior Maxilla with Autogenous Cortical Bone Laminae from Ramus

Öz

Introduction: Bone resorption and pneumatization of the maxillary sinus following tooth loss are physiological processes in posterior maxilla. In advanced atrophic crests, horizontal/vertical bone and sinus augmentations are performed with high predictability and success rates with proper case selection and planning. In this case, 3-dimensional bone augmentation was performed using autogenous cortical bone laminae from ramus, in addition to lateral approached sinus floor augmentation, to prepare the area for implants. Materials and Methods: Following full-thickness flap elevation in the region with a residual ridge height of 1 mm, lateral approach sinus floor augmentation was performed with xenograft. Cortical block with dimensions of 20x10x4 mm harvested from the left mandibular ramus with piezosurgery and was seperated into 2 laminae of 1,5 mm thickness and fixed with mini screws to create occlusal and buccal walls. Autogenous graft collected from the donor area with bone scraper was mixed with xenograft and placed between the walls. The edges of the laminae were smoothed. Flap was advanced with periosteal releasing incisions and closed with 5.0 polypropylene suture. After 8 months, the mini screws were removed and two 4,5x11.5 mm implants were placed in sites #25 and #27. Results: Bone height was increased from 3.5 mm to 20 mm in site #25 and from 1 mm to 17 mm in site #27; bone width of 7 mm was obtained. After 8-month healing, implants were placed and patient was prepared for the prosthetic phase. Discussion & Conclusion: In cases where the residual ridge height and width are insufficient for implant surgery as a result of bone resorption and sinus pneumatization following tooth loss, the use of thin cortical bone laminae harvested and split from the mandible ramus, with particulate graft between them, acting as occlusal and buccal walls, gives successful results in 3-dimensional reconstruction of the posterior maxilla with predictable gain and minimal graft resorption.
