Objective: To study the relationship between Haversian remodeling and bone regeneration in guided bone regeneration (GBR).
Method: 10 mm long segmental defects were created in the diaphyses of one radius in 24 rabbits. The defect was covered with silicone membrane shaped as a tube. Rabbits were killed at the 3rd day, 1st, 2nd, 3rd, 4th, 6th, 10th, 12th weeks. Undecalcified section was prepared for histologic examination.
Result: Bone resorption was seen in Haversian canal, connection between osteocytes and osteoblasts in Haversian, and connection of osteoblasts in Haversian and in callus. The process of Haversian remodeling was involved in the process of bone regeneration, just like primary bone healing. The process of Haversian remodeling and regeneration was coupled in topography, time and size.
Conclusion: Bone repair is related to Haversian remodeling.
