Abstract
Aim: To assess which slice inclination would be more accurate in measuring sites for implant
placement: the oblique or the orthoradial slice. Methods: Five regions of eight edentulous
mandibles were selected (incisor, canine, premolar, first molar and second molar). The mandibles
were scanned with a Next Generation i-CAT CBCT unit. Two previously calibrated oral radiologists
performed vertical measurements in all the selected regions using both the oblique and orthoradial
slices. The mandibles were sectioned in all the evaluated regions in order to obtain the gold
standard. The Wilcoxon signed rank test compared the measurements obtained in the oblique and
orthoradial slices with the gold standard. Results: The bone height measurements for the first and
second molar regions using the orthoradial slices were statistically different from the gold standard.
Conclusions: Using the orthoradial slices to obtain cross-sectional images may offer insufficient
accuracy for implant placement in the posterior region.
