Subperiosteal Ridge Augmentation Technique Utilizing Sticky Bone: A Case Series

This case series presents the application of a novel minimally invasive technique for augmenting ridge defects across four edentulous sites, thereby circumventing common postoperative complications associated with conventional ridge augmentation techniques. The case series details three cases encompassing four edentulous sites with class I and III ridge defects. This approach uses a minimally invasive subperiosteal technique for ridge augmentation, followed by a delayed implant placement. Subperiosteal incisions were made mesial to the edentulous sites, and subperiosteal pouches were created using tunneling instruments. Sticky bone (comprising injectable platelet-rich fibrin (IPRF) and xenograft) was applied to the pouches, followed by Vicryl suturing. The cone-beam computed tomography (CBCT) assessed dimensional changes between baseline and 180 days post-ridge augmentation. Subsequently, during implant insertion after 180 days, bone samples were collected, decalcified using 10% formic acid, and sectioned to a thickness of 5 µm. Histological analysis of the bone samples was conducted using a bright field microscope, while histomorphometric analysis was carried out using Image J software. The modified subperiosteal tunneling technique employed in this case report, coupled with using sticky bone as an augmentation material, demonstrates promise as a reliable method for ridge augmentation.
