Patient and Parental Satisfaction Following Treatment of Anterior Crossbite in Mixed Dentition: A Comparative Study of cemented lower inclined plane (CLIP) and removable anterior expansion screw (RAES)

Abstract

Abstract Introduction: Anterior crossbite in mixed dentition is one of the problems that require early intervention aiming at stimulating well balance growth and occlusal development. Aim: of the comparative study was to assess patient and parental satisfaction following the treatment of anterior crossbite in the mixed dentition using: cemented lower inclined plane (CLIP) and removable anterior expansion screw (RAES). Methods: Thirty-four children (17 per group) who had received either CLIP or RAES for the correction of anterior crossbite in the mixed dentition. Patient and parental satisfaction was assessed using a validated questionnaire, which included items related to treatment experience, and overall satisfaction. Statistical analysis: Fisher’s exact or χ2 test, for categorical variables, and a two-sample Wilcoxon rank sum (Mann–Whitney) test for continuous data were performed to investigation differences between the two groups. Results: In terms of treatment duration, RAES appliance, with most participants who received RAES appliance reported that the treatments lasted longer than expected compared to the CLIP (p-value: <0.001). Parents reported that RAES appliances were more enjoyable to wear by children. Regarding functional improvement, both groups reported similar levels of satisfaction. (CLIP: 94%, RAES: 92%). Overall, patient satisfaction was comparable between the two study arms. Conclusion: Both CLIP and RAES treatment modalities were effective in the treatment of anterior crossbite in the mixed dentition, and showed high levels of patient and parental satisfaction. CLIP was notably perceived as a more painful intervention than RAES.
