Orthodontic aligner therapy outcomes in children with autism spectrum disorder.

BACKGROUND

Children with autism spectrum disorder (ASD) face unique challenges in oral care. Aligner therapy offers a promising alternative to conventional approaches for this patient group.

AIM

To evaluate orthodontic aligner therapy outcomes in children with ASD using the Peer Assessment Rating (PAR) Index and the Index of Complexity, Outcome, and Need (ICON), and to investigate whether concomitant disorders affect ICON, PAR scores, and treatment duration.

DESIGN

Two calibrated observers assessed digital dental casts and intraoral pictures of 37 children with ASD before (T0) and after (T1) their treatment. At T0, the participants' average age was 12.9 years (SD = 1.68); at T1, post-therapy, the average age was 14.9 years (SD = 1.51). All participants underwent orthodontic aligner therapy. Statistical methods employed in this study included descriptive analysis, Wilcoxon tests, and univariate linear regression.

RESULTS

Posttreatment, median ICON scores decreased significantly from 74 to 14, and median PAR scores from 36 to 8 (p < .0001), demonstrating "excellent to substantial" improvement in 89.2% (n = 33) of the children. Comorbidities, present in 62% of patients, did not significantly affect treatment duration (22.6 ± 11.02 months).

CONCLUSION

Children with ASD significantly benefit from orthodontic aligner therapy, emphasizing the need for tailored orthodontic care.
