Postoperative care was similar for both extraction and implantation. The sutures were removed after 7 to
10 days and a soft diet was provided throughout the study period. The dogs were sacrificed after 12 weeks by
anesthesia overdose. Block sections, including segments with implants, were preserved and fixed in 10 %
neutral buffered formalin.
Results:
1.Clinical observations
During the postoperative period, healing was uneventful and implants were well maintained. There were no
sign of inflammation in the mucosa adjacent to the implants.
2. Histological Observations
Examination revealed that the defect was incompletely filled with the bone in the control group (Figure 1).
In the coronal portion of the defect, the lateral border of the newly formed bone was not in contact with the
implant surface. A dense layer of connective tissue was observed in the space and in direct contact with the
implant surface.
On the other hand, the defect was healed and filled with new bone in both experimental groups (Figure 2, 3).
This newly formed bone presented many osteocytes and showed good integration with the osteoblasts lining the
implant surface.
