M a t e r i a l s a n d m e t h o d s Thirty-nine mandibles from adult cadavers were examined. Eighteen tomographic sliceswere performedforeach mandible, usingthe occlusal andthebasalplanesasaxialreferenceplanes.Theradiographicmeasure- mentsobtainedusingthetworeferenceplaneswerecomparedwithbone measurements taken using a digital calibrator. R e s u l t s Discrepancies, which varied between 0.03 mm and 1.47 mm, were found between measurements taken from CT scans and measurements taken directly from the bone. When the distribution of discrepancies was con- sideredinrelationtotheaxialreferenceplaneused,itwasfoundthatwhen the basal plane was used, a higher percentage of discrepancies of over 0.5 mm occurred (99.44%) than when the occlusal plane was used (44.44%), with the difference being statistically significant (p = 0.001). C o n c l u s i o n ThediscrepanciesbetweenCTradiographicmeasurementsanddirectbone measurements should be taken into consideration in order to achieve sat- isfactorydentalimplanttreatments.Withregardtopositioningthepatient when CT scans are taken, use of the occlusal plane as axial reference will produce the most accurate measurements.
