Comparing Customized Allogenic and Autogenous Bone Block Grafts for Alveolar Ridge Augmentation in Patients Needing Dental Implants

What this Trial Is About

Researchers are evaluating whether jawbone augmentations using two types of bone blocks, allogeneic donor bone and autogenous patients own bone, result in similar three-dimensional clinical and radiological outcomes. The study also aims to compare safety, biocompatibility, complications, and patient-reported outcomes. Additionally, it investigates differences in implant condition one year after implantation and during annual follow-ups for up to five years. The study involves two treatment groups one receiving customized allogenic bone block augmentation designed with 3D technology based on the patients CTCBCT scans, covered with a collagen-based membrane and the other receiving autologous bone block grafts adapted to the defect site and immobilized with screws, sometimes supplemented with bone particles. Both procedures target patients with insufficient bone volume to allow standard implant placement. Participants will be followed over several years with evaluations of ridge width gain measured at multiple time points, including screening, 180 days after augmentation, and annually for up to five years after the second stage surgery. Researchers will monitor clinical and radiological outcomes, implant conditions, and patient experiences throughout the study period. The total participation duration extends up to five years after implantation to assess long-term results.
