Background.
To date, insertion torque value (ITV) and implant stability quotient (ISQ) obtained by the Osstell instrument are common clinical methods to assess the initial stability of an implant for a predictable loading procedure.
The aim of this current study is to evaluate the ITV and ISQ as stability parameters as part of the decision-making protocol in the adoption of immediate loading in fresh extraction sockets.
Materials and Methods.
A total of 41 tapered implants were allocated into two groups: the test group (n = 11; 3 males and 8 females; mean age: 62.8 ± 10.7) which received 18 implants as type 1 fresh extraction sockets after teeth removal and the control group (n = 7; 4 males and 3 females; mean age: 65.4 ± 9.7) which received 23 implants placed in healed sockets for a period of at least 3 months.
Both the ITV and ISQ data were recorded at the time of insertion (t0).
Since ITV (test group) and ITV/ISQ (control group) values were useful for the immediate loading protocol, a screw-retained temporary crown was immediately loaded.
ISQ values were recorded after a healing period of 4 months (t1).
Results.
ITV mean values at t0 in test and control groups were, respectively, 48.61 ± 15.39 and 70.47 ± 14.71, whereas ISQ mean values were 57.55 ± 1.93 and 72.86 ± 5.25, respectively, showing a statistically significant difference (p value < 0.001).
ISQ mean values at t1 in either the test or the control group were 68.68 ± 4.20 and 74.54 ± 4.17, not showing a statistical difference.
The implant survival rate was 100% in both groups, and no surgical and prosthetic complications were reported during the study.
Conclusion.
In conclusion, this study remarked the presence of a residual gap that influenced the ISQ during implant insertion in fresh extraction sockets making this parameter not sufficient for a conclusive decision in the immediate loading, whereas the ITV alone showed to be the best parameter for a final substantial decision.
