Orthosystem: software for the mixed dentition analysis

Introduction The analysis of mixed dentition is essential for diagnosis in Orthodontics to estimate size of unerupted permanent teeth and evaluate if the dental volume is in accordance with the arch lenght. Currently, there are softwares that perform the analysis of dental casts in 2D and 3D. However, these programs are still very expensive. Aim The aim of this study was to develop a software (OrthoSystem) to be used by undergraduate and postgraduate orthodontics students to perform the mixed dentition analysis of Moyers. Method To evaluate the accuracy and the time consumption, 60 pairs of dental casts were evaluated according Moyers analysis both manually and through the use of the software. Questionnaires were administered to 72 undergraduate Dentistry students to test the usability of the program. Result The program had the accuracy validated, showing a perfect agreement (p = 1) and a time consuption of 4.2 minutes less when compared with the manual method to do the mixed dentition analysis. In addition, the OrthoSystem was considered excellent in usability and better than the conventional method by the students. Conclusion The OrthoSystem software is efficient and was considered excellent for undergraduate Dentistry students.
