The development of oral implantology has led to the establishment of various image-acquisition
methods as important surgical diagnosis tools, such as linear (LT) and cone beam computed
tomography (CBCT), indicated for planning implant placement surgeries. However, there still is
little information in the literature regarding details on the difference between the accuracy of these
Aim: The aim of the present study was to assess the difference between the accuracy
of LT and CBCT in measuring ridge bone width.
Methods: A sample of ten human skulls was
used, totaling 40 edentulous sites, marked with 2-mm gutta-percha balls in the buccal and lingual
plates. Buccal-lingual measurements of ridge width were performed on the images of both
tomography types. Direct caliper measurements were used as control values, to which all LT and
CBCT measurements were compared.
Results: CBCT images showed significantly more accurate
results in comparison with the direct caliper measurements (p<0.05).
proved more reliable than LT regarding ridge bone measurements for dental implant planning.
