Abstract: | AbstractObjectives: To investigate the effectiveness of an upper removable appliance in the treatment of an anterior crossbite in term of quality of life, effectiveness, treatment time, long term stability and cost minimization.Design: Systematic reviewData source: A search strategy was implemented using both manual hand search and electronic databases, including Cochrane Central Register of Controlled Trials (CENTRAL), PubMed, ScienceDirect, Scopus and Ebsco.Study eligibility criteria: Randomized controlled clinical trialsParticipants: Children in the early or late mixed dentition with an anterior crossbite affecting one or more incisors, and no underlying skeletal class III pattern.Interventions: Upper removable appliance compared with other orthodontic appliances.Study appraisal and synthesis: All potential articles were checked against the inclusion criteria independently, and in duplicate by two investigators. Risk of bias of eligible studies to be included in the final analysis was assessed independently by two authors using Cochrane risk of bias tool.Results: A total of 524 articles were identified in both manual and electronic searches as well as by checking the reference lists of the final articles to be included in the study. Only 7 reports of 3 RCTs met the inclusion criteria and thus were included in the final analysis. All but one of the 3 RCTs were judged to be of very low quality. No statistical methods were employed to combine the studies due to the heterogeneity of the studies.Conclusion: A fixed appliance was more cost-effective than a removable appliance in the correction of an anterior crossbite with a functional shift. There was no significant difference in terms of quality of life, pain intensity or long-term stability between the two appliances. On the other hand, both a removable appliance and cemented bite-pads were equally effective in the correction of an anterior dental crossbite without having any side effect. |
