Abstract

Objective: To evaluate the reasons influencing prospective patients (PP) and orthodontists to prefer a type of orthodontic appliance over another. Methods: 49 PP and 51 orthodontists were asked about their preferences for the following appliances: Clear aligners (CA), Lingual metallic brackets (LMB), Polycrystalline and Monocrystalline ceramic brackets, and Buccal metallic brackets (BMB). Subjects rated the importance of 17 potential reasons that would explain their choices. Those reasons that would most contribute to these decisions were identified. In addition, it was evaluated whether the provision of appliances-related information modified the participants’ preferences. Non-parametric tests (Fisher’s exact, χ² and Mann-Whitney tests) and multivariate analyses (regression and discriminant analysis) were used to assess the data (α=0.05). Results: CA and BMB were the most chosen appliances by PP and orthodontists, respectively. LMB was the most rejected option for all participants (p<0.001). Rates on the importance of pain/discomfort, smile aesthetics, finishing details, and feeding/speech impairment, showed the highest differences between PP and orthodontists (p<0.0005). Discriminant analyses showed that individuals who considered treatment time and smile aesthetics as more important, were more likely to prefer CA; those who prioritized finishing details and cost, were more likely to choose BMB (p<0.05). Receiving appliances-related information changed the preferences of PP (p<0.001). Conclusion: Reasons related to comfort and quality of life during the use were considered as more important by PP, those related to the results and clinical performance of the appliances were considered as more relevant for orthodontists.
