Material and Methods:In our study, three dogs were selected. The second premolar at each site of the mandible was extracted. In each dog, one site was selected randomly as the control site (G1), and immediate implantation was done with a standard primary stability. In three other sites, an oversized osteotomy was performed, and then the sites were randomized to receive either an implant with zero torque and secured withβTCP and FDBA (G2) or secured withβTCP, FDBA and silicate cement (G3). Four months after surgery, Individual bone blocks containing of implants were harvested. After dissection, specimens were evaluated using a stereomicroscope (Olympus, Japan). The mean bone to implant contact (BIC) was measured and compared between groups by ANOVA. Results: Two implants were not successfully osseointegrated. One of them failed in the G2 group and the other was in the G3 group. The mean BICs in the G1, G2, and G3 groups were 30.6%, 60.7%, and 72%, respectively. The results of ANOVA showed that BIC was not significantly different between these three groups (P value = 0.08). Conclusions:According to our findings, the absence of primary stability when we used graft materials did not increase the failure rate in comparison to the control treatment. Another finding was that the amount of BIC in implants without primary stability was not significantly different from that in stable implants.
