Purpose: Autogenous bones are frequently used because of their lack of antigenicity, butgood osteoconductive and osteoinductive properties. This study evaluated the biologicalbehavior of perforated and nonperforated cortical block bone grafts. Methods: Ten nonsmoking patients who required treatment due to severe resorption of thealveolar process and subsequent implant installation were included in the study. The inclusioncriteria was loss of one or more teeth; the presence of atrophy of the alveolar processwith the indication of reconstruction procedures to allow rehabilitation with dental implants;and the absence of systemic disease, local infection, or inflammation. The patientswere randomly divided into two groups based on whether they received a perforated (innersurface) or nonperforated graft. After a 6-month healing period, a biopsy was performedand osseointegrated implants were installed in the same procedure. Results: Fibrous connective tissue was evident at the interface in patients who receivednonperforated grafts. However, full union between the graft and host bed was visible inthose who had received a perforated graft. Conclusions: We found that cortical inner side perforations at donor sites increased thesurface area and opened the medullary cavity. Our results indicate an increased rate ofgraft incorporation in patients who received such perforated grafts.
