Abstract
Background: Orthodontics has been influenced by new technologies in many areas. There is a shift toward digitization of patient’s information and data. Aim: The aim of this study was to compare the accuracy of intraoral scanner and extra oral scanners using different dental arch measurements. Materials and Methods: The sample size consisted of 44 dental stone models for patients who finished orthodontic treatment. For each subject two digital models were made, one digital model obtained from extra oral scanner and one digital model obtained from Intra oral scanner. An external examiner measured intermolar width, intercanine width, mesiodistal width of the first and second premolars on both left and right sides using ortho analyser 3shape programs from STL files. The same examiner evaluated the same measurements direct on the dental stone model using digital caliper. Results: The results showed no statistically significant difference between the two tested models, digital models versus stone models. Conclusions: Both intra oral and extra oral scanners were reliable on producing accurate digital models
