Posterior crossbite corrections in the early mixed dentition with quad helix or rapid maxillary expander: a cost-effectiveness analysis of a randomized controlled trial

Posterior Crossbite Corrections in Early Mixed Dentition: Cost-Effectiveness Analysis

Background

Unilateral posterior crossbite is a common dental issue in children, and early treatment is recommended for normal growth. The choice of appliances for correcting this condition is important, especially when considering the cost-effectiveness of treatment.

Objectives

This study aimed to compare the cost-effectiveness of quad helix (QH) and rapid maxillary expanders (RME) in children in the early mixed dentition.

Results

– The success rate of both QH and RME was similar.
– From a healthcare perspective, the mean cost difference favored QH by €32.05.
– From a societal perspective, the mean cost difference was €32.61 in favor of QH.
– The total appliance cost alone was higher in the RME group.
– The probability of RME having a higher cost was 71% from a healthcare perspective and 62.7% from a societal perspective.
– The total treatment time was 97 days longer in the QH group.

Conclusion

While the cost difference between RME and QH is not statistically significant, there is a slightly higher probability that RME is more expensive than QH. Different work procedures at different centers indicate that logistics around the patient’s treatment are more important than the appliance used to decrease the number of visits and save chair time and costs.
