Overall implant survival rate was 93.3%. Two implants failed, one implant in group A (OSPTXSoft) and one in group B (OSPTXStd). Both implant failures occurred at the time of uncovery (at 6 weeks) and prior to loading of the implants and were attributed to lack of integration. With the exception of these two failed implants, there was 100% success for all remaining implants using the parameters described in Table 2. There are no statistically significant differences in mean crestal bone loss at 6 and 12 months (Fig. 3) or ISQ at insertion, 6 weeks and 6 and 12 months (Fig. 2) in between the three groups. Implant stability, as measured by ISQ, ranged between 83 and 84 at the 12-month time point in all groups (Fig. 2). Mean radiographic crestal bone loss at 6 and 12 months after implant placement was minimal (<0.5 mm) in all groups with no statistically significant difference between the groups (Fig. 3). Implant stability, as measured with ISQ, presented no statistically significant difference between the three groups at the time of insertion and at 6 and 12 months. Strong positive correlations were found between overall bone loss at 6 months and insertion torque at time of placement (r = 0.7998). When evaluating the correlation between torque values at the time of implant placement, a strong positive correlation was found with overall bone loss at 6 months (r = 0.7995) and with ISQ at 6 weeks (r = 0.9078). Insertion torque and ISQ at time of implant placement presented a very weak correlation (r = 0.0509).
