摘要: Objectives:To investigate the reliability and accuracy of cone beam CT (CBCT) images obtained at different fields view in detecting quantifying simulated buccal marginal alveolar peri-implant defects.Methods:Simulated defects were prepared 69 implants inserted into cadaver mandibles. CBCT three acquired: 40 × 40, 60 × 60 100 × 100 mm. The presence or absence was assessed on sets using a five-point scale by observers. Observers also measured depth, width volume images, which compared with physical measurements. kappa value calculated to assess intra- interobserver agreement. Six-way repeated analysis variance used evaluate treatment effects diagnosis. Pairwise comparisons median true-positive true-negative rates χ2 test. Pearson's correlation coefficient determine relationship between Significan...
