Abstract:

 Objective: The aim of this study is to evaluate the accuracy, reliability and reproducibility of measurements made on digital models obtained using OrthoAnalyzer 3Shape, Copenhagen, Denmark and Materialize 3 matic MIMICS , Leuven, Belgium software by comparing them with measurements made on dental plaster models. Methods: The teeth of 50 individuals were measured and plaster models were obtained. In addition, digital images were obtained from the patients with Trios intraoral scanner. A total of 30 linear measurements were made using OrthoAnalyzer and Materialize 3 matic software, including the mesiodistal width of the teeth, arch perimeter, intercanine and intermolar distances. All measurements were made by two different examiners. For the first and second measurements of the first examiner, intraexaminer reliability was calculated using intraclass correlation coefficients ICCs, two way mixed model, consistency type. Results: The largest mean difference between Materialize 3 matic and caliper measurements was -0.136 mm in maxillary right first premolar and maxillary left lateral incisor. The smallest mean difference was 0.0029 mm in the mandibular left lateral incisor. In transverse measurements, the largest mean difference was found in the upper intercanine distance of 0.117 mm, and the smallest mean difference was 0.0086 mm in the upper intermolar distance. The largest mean difference between OrthoAnalyzer and caliper measurements was 0.107 mm in the maxillary right lateral incisor, and the smallest mean difference was 0.0049 mm in the maxillary left lateral incisor. Conclusions: Linear distance measurements with three-dimensional digital models are a valid, reliable and reproducible method compared to plaster models.
