Effect of clear aligners and Z-spring appliance on anterior crossbite correction and quality of life in the mixed dentition: a randomized clinical trial.

ABSTRACT:

Objectives

To compare the efficacy of clear aligners and Z-spring (ZS) appliances in treating dental anterior crossbite (AC) during the mixed dentition period.

Materials and methods

Thirty patients (7-12 years) with Angle Class I occlusion and isolated pseudo-Class III AC were randomly assigned to clear aligners (Group A, n = 15) or ZS appliances (Group B, n = 15). Outcomes were evaluated based on duration, cephalometric changes, model analysis, and oral health-related quality of life (OHRQoL), assessed using the Child Oral Health Impact Profile-Short Form-19 (COHIP-SF-19).

Results

AC was successfully corrected in all patients. Treatment duration was significantly shorter in Group B (48.4 ± 27 days) than in Group A (96.3 ± 22.7 days) (P < .05). U1-NA angle increased b
