Mandibulada posterior bölgeye uygulanan implantlarda preoperatif kemik kalitesi ve primer stabilite arasındaki korelasyon

Abstract

Aim: This study aimed to investigate preoperative bone quality obtained from the Hounsfield unit and fractal analysis scores in cone beam computed tomography (CBCT) sections and compare this value with primer stability derived from resonance frequency analysis scores soon after placement of implants in the mandibular posterior region. 
 Material and Method: A total of 36 implant regions were examined retrospectively. Primary outcome variables include the Hounsfield unit, fractal analysis, and resonance frequency analysis scores soon after implant placement. Hounsfield unit and fractal analysis scores were calculated on the preoperative CBCT. 
 Results: The mean Hounsfield unit, fractal analysis and resonance frequency analysis scores of all implants were 76.44, 0.65 and 67.44, respectively. No statistically significant correlation was found between the Hounsfield unit, fractal analysis and resonance frequency analysis scores (p>0.05). Resonance frequency analysis scores (p=0.002) and Hounsfield unit scores (p=0.050) were significantly superior in males. Age was found to be related to resonance frequency analysis scores (r=0.445, p=0.007). 
 Conclusion: The preoperative bone quality of alveolar bone measured from cone beam computed tomography by Hounsfield unit or fractal analysis may be insufficient to determine initial implant stability. Further studies are needed to investigate parameters related to the prediction of implant stability.
