Validation of resonance frequency analysis by comparing implant stability quotient values with histomorphometric data

The study was designed to determine the relationship between implant stability quotient (ISQ) values measured using resonance frequency analysis (RFA) and implant-bone distance measured histomorphometrically. Ten identical implants were equally divided into 2 groups based on primary stability at placement. Osteotomies were prepared in harvested goat femurs. ISQ values were measured and compared with implant-bone distance determined by micrometry. Based on the results, it was concluded that RFA can be used to measure implant stability reliably.
