Objective: To determine the implant stability in osseodistraction-generated (ODG) bone after a 2-month consolidation period, assessed by resonance frequency analysis (RFA). Material and methods: Twenty healthy, non-smoker female patients received 71 dental implants, 39 placed in native bone and 32 in ODG bone, after an 8-week consolidation period. Primary and secondary stability of the implants was assessed by means of the Osstell® mentor device. The average value of six measurements was considered for the statistical analysis at each time point. Results: The age of the patients who received implants in ODG was not significantly different from that of those receiving implants in pristine bone (48.0±10.9); [ X=1.6; 95% confidence interval (CI)=−7.7–10.9]. Although implants placed in both bone types indicated good primary stability, a statistically significant difference in favour of implants placed in pristine bone could be identified in terms of osteogenic distraction (OD) ( Xi− Xj=3.4; 95% CI=1.7–5.8). After a 1.5-month integration period, none of the implants failed, but implant stability still recorded higher values for implants located in the pristine bone ( Xi− Xj=2.5; 95% CI=0.5–4.4). A positive linear correlation could be established between the implant stability quotient (ISQ) values at implant placement (primary stability) and the post-integration ISQ score (secondary stability) for both bone types, but only 16% of the post-integration ISQ in the ODG bone could be attributed to the primary stability. Conclusions: Within the limitations of this study, OD bone offers – after a 2-month consolidation period – high primary and secondary stabilities after implant placement. [ABSTRACT FROM AUTHOR]
