title: Reliability of digital orthodontic setups.
abstract: OBJECTIVE
  To evaluate the reliability of digital orthodontic setup technology by comparing it with manual setups and models cast at the end of orthodontic treatment.
  
  
  METHODS
  Initial models, manual setups, and final models of 20 patients were used. The initial and final models, as well as the manual setups, were scanned using a 3Shape R-700 scanner, while the digital setups were fabricated based on the initial models using 3Shape OrthoAnalyzer software. Evaluation of the models based on the manual setup, digital setup, and final models of each patient was performed using the following linear measurements: intercanine widths, intermolar widths, and length of the upper and lower dental arches.
  
  
  RESULTS
  The results disclosed that none of the measures assessed through the manual setup, digital setup, and final models showed statistically significant differences (P > .05).
  
  
  CONCLUSIONS
  Based on these findings, it can be inferred that digital setups are as effective and accurate as manual setups and constitute a tool for diagnosing and treatment planning that can be reliably reproduced in orthodontic treatments.
