In cases of severely atrophic edentulous maxilla, reconstruction, including lateral sinus floor elevation (LSFE) and alveolar ridge augmentation is performed using anorganic bovine bone matrix (ABBM) and/or autogenous bone. In this case, a 1:1 mixture of ABBM and octacalcium phosphate (OCP) was used for bilateral LSFE and vertical ridge augmentation. After a 7-month healing period, seven implants were successfully placed in the regenerated bone without the need for additional bone grafting. Core biopsy revealed a new bone formation rate of 43.8%. Among the residual graft materials, OCP and ABBM accounted for 2.9% and 7.1%, respectively and connective tissue comprised 46.2%. Within the limitations of this case, the combination of ABBM and OCP appeared to be a reliable choice for bone regeneration.
