Análisis comparativo entre las técnicas de medición manual-tradicional y digital de los espacios intercanino e intermolar en modelos de estudio

Abstract

Introduction: The aim of this study was to compare manual - traditional and digital measurement techniques for analysis of intercanine and intermolar spaces. The study models of 27 patients in the Orthodontic Department of the School of Dentistry at the Universidad de Cuenca were used to determine whether or not the two evaluation techniques were coincidental at the time of measurement.

Materials and methods: A physical and a digital model of each of the 27 patients meeting the inclusion criteria were used from the files between March 2013 and October 2015. The manual-traditional analysis was performed using a digital caliper Mitutoyo 500-196-30. The digital analysis was done with diagnostic software NemoCast 3D models. The SPSS 19.0 program was used to study the data. The Kolmogorov-Smirnov Test was used to determine normality, consequently the Student T–Test was applied. The researchers involved in the analysis had previous training on standards and work manuals for the appropriate handling of a digital caliper and a digital scanner.

Results and conclusions: The results of the measures are: the manual - traditional intercanine measurement space is 0.642 and digital intercanine measurement space is 0.684, while manual - traditional intermolar measurement space is 0.770 and digital intermolar measurement space is 0.640 ; these results obtain a nonsignificant difference of 0.717 intercanine space and 0.130 intermolar space; this verifying the hypothesis that is no difference between measures of intercanine and intermolar spaces obtained from manual - traditional and digital techniques
