Satisfaction with treatment outcomes of cemented lower inclined plane versus removable anterior expansion screw for treatment of anterior crossbite in mixed dentition: A cross-sectional study”

Abstract

Introduction: Anterior crossbite in mixed dentition is one of the problems that require early intervention aiming at stimulating well-balanced growth and occlusal development. Aim: to assess patient and parental satisfaction following the treatment of anterior crossbite in the mixed dentition using a cemented lower inclined plane (CLIP) and removable anterior expansion screw (RAES). Methods: Thirty-four children (17 per group; with sex match) who had received either CLIP or RAES for the correction of central incisor/s crossbite in the mixed dentition participated in the survey. The mean age of participants in the RAES group was (9.5 ± 0.6years), while in the CLIP group (8.9 ± 0.7years). 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 investigate differences between the two groups. Results: In terms of treatment duration, most participants who received RAES appliances reported longer treatment duration 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%). Patient satisfaction was comparable between the two study arms. Conclusion: Both CLIP and RAES treatment modalities were effective treatment of anterior crossbite and showed high levels of patient and parental satisfaction. CLIP was notably perceived as a more painful intervention than RAES.
