Materials and methods: Data collection was performed using semi-structured interviews with 10 orthodontists from diverse professional backgrounds. The analysis was performed using the “Grounded Theory” methodology, using Atlas.ti v.6.0.15. Results: We interviewed four men and six women (31 to 75 years old), with 7 to 53 years of experience as dentists, and 1 to 10 years of experience as orthodontists. All orthodontists have experience in private practice, five in public service, and one in a military institution. One-hun-dred and thirty-three codes were grouped into seven categories identified as follows: perception of orthodontists, control over treatment, ROA characteristics, ROA indications and contraindications, patients’ attitude to ROA, selection of treatment, and ROA utilization. Conclusion: In the selection of ROA, different factors are involved, including the characteristics of the dentist, of the patient, and the social context. The key factor in the utilization of ROA is the perception of control over treatment.enAttitudeControl over treatmentGrounded theoryPerceptionsQualitative analysisRemovable orthodontic appliancesArtículo
