-- The current use in several countries in Orthodontics computer programs and the introduction of digital study models have changed the traditional way of performing measurements on them, while eliminating the disadvantages of the method of manual measurement. Using a new method of measurement would allow the development of software as an auxiliary tool for automatically obtaining a large number of measures for orthodontic indices both in the mixed dentition and permanent, from scanning and calibrated correctly prior on the scanned image to ensure the accuracy of the measurement. This study aims to compare a new digital measurement method in two dimensions (2D) by using a software developed by the researcher for use in the analysis of Bolton, and used as a resource that allows us to make it easier to measure in study models. Was conducted in a population comprised of 104 school study models from 12 to 18 year old SJL GAM EI 139. Of a total of 120 models according to the criteria of inclusion and exclusion, with a descriptive, comparative and cross in order to identify differences in the diameter measurements and the discrepancy mesiodistal obtained from the analysis of Bolton using the digital measuring method and the manual measurement method. The instrument used for the manual measurements was a proximate digital caliper with 0.02 and precision digital measurements was pre-scanning and calibration of study models, marking for their points of contact tooth mesial and distal statistical data were evaluated with SPSS software version 15, looking mean and standard deviation and the use of the t-paired student for determining significance. The study results show that when comparing the averages of the mesiodistal diameters measured using the method of manual and digital differ-0.17054808mm (1 PMSD) and 0.14061923mm (ICSD).
