The use of Human Allogenic Graft (HBA) for Maxillary Bone Regeneration: Reviewof Literature and Case Reports

The use of graft materials is developed from the strong demand to support the complete bone regeneration of the empty socketand to increase the bone volume in treating the atrophies of sites already consolidated and with adverse alveolar bone conditions. A numberof graft materials with different origin and mechanism of bone regeneration are available. Autologous graft materials, coming fromthe same patient, are defined as the gold-standard. The need of a second surgical site and the risk of morbidity and complications maymake their use difficult. Human bone allografts (HBA) have been recently introduced, in order to offer an alternative to the autologousgrafts. They have demonstrated to be effective in bone regeneration. Recent studies have proved the ability of HBA in bone regeneratingprocess as they guarantee a three-dimensional structure for the re-growth of the new bone and the maintenance of inductive stimuli. In thepresent manuscript, Authors reviewed the evidence supporting the use of HBA in the management of the localized ridge atrophies, in thepreservation of the extracted socket and in the sinus augmentation surgery, and illustrated some original case reports.
