Evaluation of Patient-reported Outcome Measures during the Correction of Skeletal Class III Malocclusion with Maxillary Constriction in Early Adolescence

Le résumé fourni par la source

AIM: This randomized controlled trial (RCT) aimed to evaluate the patient-reported outcome measures (PROMs) when treated with the bone-anchored intermaxillary traction (BAIMT) associated with rapid maxillary expansion (RME) and the removable mandibular retractor (RMR) associated with slow maxillary expansion (SME). MATERIALS AND METHODS: This was a single-center 2-arm RCT accomplished between September 2021 and September 2023 involving patients aged between 12 and 15 years and diagnosed with skeletal class III (SCIII) and maxillary constriction. The patients were randomly divided into the BAIMT/RME group and the RMR/SME group. The levels of pain, discomfort, and functional impairment were evaluated by a standardized questionnaire at five assessment times: (T1) after a day, (T2) after a week (T3) after 4 weeks, (T4) after 3 months, and (T5) after 6 months following treatment onset. RESULTS: > 0.01). CONCLUSION: Treatment of class III malocclusion in growing patients by both appliances did not negatively affect PROMs. Moreover, the application of both appliances was associated with a gradual improvement in the levels of pain and functional impairments until they were almost nonexistent after 6 months. CLINICAL SIGNIFICANCE: Application of both the BAIMT/RME and RMR/SME in adolescents with SCIII patients is associated with comparable and acceptable levels of pain, discomfort, functional impairment, and shame.
