Time-Dependent Changes in Fresh-Frozen Bone Block Grafts: Tomographic, Histologic, and Histomorphometric Findings

Abstract

All three groups showed new bone formation and different bone resorption rates. Graft healing periods of 4 months showed less graft resorption and seemed to be the most favorable for implant placement. Healing periods of 8 months showed the largest rate of graft resorption, which could render the grafts unfavorable for implant placement.
