Abstract: Implant is an available ideal treatment for replacement of missing teeth. The evaluation of bone dimension is required for treatment planning. Ridge mapping is a method that can be used for bone width determination reading which can reduce some of the complications associated with imaging techniques. The purpose of this study, was to compare the accuracy of ridge mapping and spiral computed tomography with direct bone width measurement. A total of 32 implant sites from 12 patients were used. A surgical stent was designed and used for each point of measurement in mouth and on CT images. Measurements were carried out at implant sites, 4 and 7 mm from the crest of ridge before flap reflection (RM), after bone exposure (Direct Measurement = DM) both by caliper and on the spiral CT images with digital caliper. The recorded data were analyzed using t-test. The recorded data were used to construct 36 possible pairs of data which was subsequently analyzed for statistical relation. The analysis showed that only 10 pairs out of 36 possible data pairs were significantly different. In particular, pair of RM-CT data and DM-CT data showed statistically significant difference at 7 mm levels (p<0.05). Of the 12 possible pair of RM-DM data, however none showed statistically significant difference at any of the 4 and 7 mm levels (p>0.05).
