Patient and Parental Satisfaction following Orthodontic Treatment with Clear Aligners and Elastodontic Appliances during Mixed Dentition: A Cross-Sectional Case–Control Study

The aim of the current study was to assess patient and parental satisfaction following treatment during mixed dentition with two removable orthodontic devices: elastodontic appliances (EAs) and clear aligners (CAs). Consecutive patients below the age of 12 years who had completed the active phase of EA or CA therapy were recruited. A dedicated written questionnaire divided into four sections was used to measure parental and patient satisfaction regarding treatment experiences and treatment outcomes. The total sample included 56 subjects: 28 belonged to the EA group (7 girls and 21 boys; mean age 11 years); 28 belonged to the CA group (12 girls and 16 boys; mean age 9 years). Patients and parents of both the EA and CA groups were satisfied with the treatment experiences and outcomes. According to parental reporting, EA treatment was significantly more painful than CA therapy (p = 0.003), but this was not confirmed by the patients (p = 0.100). Both parents and patients reported EAs being significantly more difficult to wear than CAs (p < 0.001 and p = 0.001, respectively). Functional improvements were reported, including a reduction in grinding sounds in the CA group (p = 0.020) and breathing improvements in the EA group (p = 0.023). According to the parents, school life and social life were significantly improved in the CA group, as compared to the EA group (school life p < 0.001, social life p = 0.001). Finally, parents belonging to the CA group found that their child’s treatment was much shorter than expected (p = 0.003).
