Resumen
Objectives: Cone beam computed tomography (CBCT) is an innovative dental of imaging system characterized by rapid volumetric imaging with patient exposure to a single dose of radiation. The present study was carried out to compare the linear measurements obtained with CBCT and digital caliper in 20 mandibles from human cadavers.
Study design: A total of 4800 linear measurements were measured between different mandibular anatomical po - ints with CBCT and digital caliper. The real measurements were defined as those obtained with the digital caliper.
Posteriorly, the mandibles were scanned to obtain the CBCT images, with software-based measurements of the distances.
Results: The measurements obtained with the digital caliper were greater. The CBCT technique underestimated distances greater than 100 mm.
Conclusions: CBCT allows to obtain linear mandibular anatomical measurements equivalent to those obtained with digital caliper. The differences existing between both methods were clinically acceptable.
