Avaliação dos modelos ortodônticos digitais por meio de questionário aplicado a cirurgiões dentistas na cidade de Aracaju-SE

Abstract

Introduction: The gypsum models scanned using 3D software have become an alternative to replace the old conventional gypsum models, allowing the professional to obtain measurements such as Bolton analysis, arc width, horizontal trespass, vertical trespass and three-dimensional vision. Materials and Methods: A questionnaire containing 12 questions in a multiple choice format was applied. The questions were divided between orthodontic models of plaster, digital models and the presentation of software 3Shape - 3d viewer (3Shape, Copenhagen, Denmark). After the application of the questionnaires, the statistical analysis of the data collected in the Excel and SPSS 20.0 programs was performed, a percentage analysis of the answers and chi-square test were performed. Results: Most of the professionals use the traditional gypsum models.The advantage of using plaster models for both professional profiles was the cost with a statistically significant difference in response pattern (p = 0.001). Regarding the advantages of the use of digital models, the General Clinicians and Orthodontists reported that the easy storage and search of information with 67.85% and 81.57%, respectively, are the major advantages of the 3D model, with a response pattern (P = 0.316). When asked the pros the disadvantages of using the 3D system models both answered the cost and the infrastructure. Differences were observed between the two profiles when asked if they planned to change to 3D models in which 38.35% of Orthodontists would make the immediate change and 37.93% only plan to be observed a response pattern of (p = 0.003).Conclusion: It is possible to verify that most of the professionals make use of the plaster models, either because of the low cost or the lack of knowledge of 3D models. In this sense, one of the major drawbacks to using the 3D system would be cost and infrastructure. For this, one of the difficulties encounted with plaster models was the storage and search of information.
