ABSTRACT
PURPOSE:
Implant stability quotient (ISQ) values have been supposed to predict implant stability. However, the relationship between ISQ values and bone-to-implant contact ratio (BIC%) which is one of the predictors of implant stability is still unclear. The aim of the present study was to evaluate initial ISQ values in relation to BIC% using rabbit model. MATERIALS ANDMETHODS:
Four New Zealand white rabbits received a total of 16 implants in their tibia. Immediately after implant placement ISQ values were assessed. The measurements were repeated at the time of sacrifice of the rabbits after 4 weeks. Peri-implant bone regeneration was assessed histomorphometrically by measuring BIC% and bone volume to total volume values (bone volume %). The relationships between ISQ values and the histomorphometric output were assessed, and then, the osseointegration prediction model via the initial ISQ values was processed.RESULTS:
Initial ISQ values showed significant correlation with the BIC%. The bone volume % did not show any significant association with the ISQ values.CONCLUSION:
In the limitation of this study, resonance frequency analysis is a useful clinical method to predict the BIC% values and examine the implant stability.
