metadata.dc.description.resumo: Microscopic measurements are widely used in scientific research and the correct equipment to realize these evaluations could be critical to determine the study results. Regarding microscopic measurements, three of the most used methods are: Optical Microscopy (OM), Scanning Electron Microscopy (SEM.), and Micro-computed Tomography (MCT). It is important to select which is the best method for assessing diverse parameters, considering the operational characteristics of the method, the equipment efficiency, and the machinery cost. Therefore, the main objective of this study was to define which is the most useful measurement method for assessing magnitudes below 0.55mm. Ten dental implants, with known dimensions as defined by the manufacturer were randomly distributed. Two blinded observers assessed the distance between the second and the third screw vortex of the implants using the three suggested methods. The true distance was defined to be 0.6mm. The assessed distances were. 0.597±0.007 for OM, 0.578±0.017 for SEM, and 0.613±0.006 for MCT. The assessed distances were significantly different when the methods were compared (P>0.01). Despite these differences, all measurements were between the CAD system tolerance, defined to be within 0.05mm. It was possible to conclude that linear measurements below 0.55mm can be performed by any of the described methods.
