Deep-Frozen Allogeneic Onlay Bone Grafts for Reconstruction of Atrophic Maxillary Alveolar Ridges: A Preliminary Study

The use of block allografts to treat maxillary atrophy yielded successful outcomes. Moreover, the augmentation procedure allowed the insertion of implants in the grafted area 5 months after surgery. Therefore, on the basis of this preliminary study, deep-frozen bone allograft can be considered a promising treatment for severe maxillary atrophy, with more extensive follow-up studies being needed to confirm these preliminary data.
