title: The relationship between initial implant stability quotient values and bone-to-implant contact ratio in the rabbit tibia.
abstract: OBJECTIVE
  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.
  
  
  METHODS
  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.
  
  
  CONCLUSIONS
  In the limitation of this study, resonance frequency analysis is a useful clinical method to predict the BIC% values and examine the implant stability.
