Abstract :The objective of this study was to determine the correlation between bone density and implant stability, using computed tomography insert ignore into journalissuearticles values(CT); and resonance frequency analysis insert ignore into journalissuearticles values(RFA);. We examined a total of 97 implants in 12 patients. CT was used to determine the bone density at each implant recipient site in Hounsfield units insert ignore into journalissuearticles values(HU);. After implant placement, RFA measurements were immediately performed with an Osstell instrument, and RFA values were recorded as implant stability quotients insert ignore into journalissuearticles values(ISQ);. Bone density values ranged from 328 to 1184 HU. ISQ ranged from 48 to 80. The mean bone densities and RFA values of all 97 implants were 689.61±173.76 HU and 66.08±6.81 ISQ, respectively. A positive correlation between RFA values and bone density was found for all four regions, with the posterior maxilla yielding a correlation of r=0.603, posterior mandible r=0.622, anterior mandible r=0.834, and anterior maxilla r=0.838. Our data confirm the correlation between ISQ and bone density.
