Abstract:
Accurate assessment of alveolar ridge width is critical for implant planning. Therefore, it is of interest to compare measurements from orthopantomography (OPG) and cone-beam computed tomography (CBCT) with direct intraoperative caliper evaluation in 50 posterior mandibular sites. CBCT values (6.15 ± 1.14 mm) closely matched direct measurements (6.18 ± 1.12 mm) with no significant difference (p=0.68). OPG significantly overestimated ridge width (7.64 ± 1.55 mm; p<0.001). CBCT demonstrated high reliability within ±0.5 mm accuracy in 94% of cases, supporting its role as the gold standard for pre-surgical width analysis in implant dentistry.

If the observed data point lies above the line, the residual is positive, and the line underestimates the actual data value for y. If the observed data point lies below the line, the residual is negative, and the line overestimates the actual data value for y.
