Abstract Objectives: Assess the interobserver concordance of magnetic resonance imaging (MRI), and the concordance between the MRI and computed tomography (CT) for obtaining the measures to be used in the dental implantation surgical planning and check the impact of such measures on the selection of implantation size. Methods: A prospective, cross-sectional, self-paring and double-blind study was carried out between 2005 and 2007 in 10 patients (3 men and 7 women) with ages ranging from 26 to 66 years old (average age of 44.2 years) with clinical indications of dental implantations in 24 bone sites, which were submitted to MRI and CT tests for obtaining bone height and thickness measures. MRI and CT tests were analyzed by four independent examiners (two for TC and two for MRI). Bone height and thickness measurements were sent to two specialists so that they could select the implantation measurements to be used in each case. An intraclass correlation statistical test was used in the assessment of the measurements obtained. Results: A high index of correlation was observed among the bone thickness measurements obtained by specialists and among the tests. However, there was a lot of divergence among specialists as regards the type of implantation to be used in each case. Conclusions: The chosen method presents high reproducibility. Bone height and thickness measurements in the MRI and CT tests presented high concordance. There was low concordance in the selection of the type of implantation in view of the average of measures obtained through MRI.
