| Abstract |
Twenty implants of 3.75mm in diameter(Neoplant, Neobiotech, Korea) were used to evaluate the
correlation between the resonance frequency analysis (RFA) and the radiographic method for periimplant
bone change under in vitro conditions. To simulate peri-implant bone change, 2mm-deep
45° range horizontal defect and 2mm-deep 90° range horizontal defect area were serially prepared
perpendicular to the X-ray beam after conventional implant insertion. ISQ values and gray values
inside threads were measured before and after peri-implant bone defect preparation. ISQ value of
resonance frequency analysis was changed according to peri-implant bone change and gray value of
radiographic method was changed according to peri-implant bone change. In horizontal defect
condition, relatively positive correlation were between ISQ and gray values(r=0.663). |
