One 60 years-old patient was scheduled for left posterior maxillary ridge augmentation due to failure of standard implants, followed by successful maxillary dental implants. We used an unproved technique consisting in a mixture of 50% allogenic and 50% xenogenic bone supported by reabsorbable membrane. No complications were found at the different stages of the treatment, and at the ending the patient showed a good level of satisfactory outcomes. Radiological evaluation demonstrated ridge augmentation able to support implant, and within the graft islands of connective and bone-like tissue was found. Within these tissues osteoclasts and osteoblast putative cells were found. Results demonstrate that the used method in addition to support implants has osteogenic and bone remodeling activity.
