Longitudinal Study on the Impact of Orthodontic Treatment Timing on Skeletal and Dental Development in Adolescents.

INTRODUCTION

The timing of orthodontic treatment can significantly impact skeletal and dental development, particularly during the adolescent growth spurt. This study investigates the influence of early, mid, and late-treatment initiation on mandibular growth, dental alignment, and occlusal correction in adolescents.

METHODS

A total of 60 adolescents were divided into three groups based on their skeletal maturity: early, mid, and late. Key parameters including mandibular growth, dental alignment, and occlusal changes were measured at baseline, mid-treatment, and post-treatment. A two-year follow-up was conducted, and a cephalometric analysis was performed.

RESULTS

The early-treatment group showed the most significant skeletal changes, particularly in mandibular growth. The mid and late groups demonstrated better dental alignment outcomes. Statistical analysis revealed significant differences in mandibular growth between groups ( < 0.05).

CONCLUSION

Treatment timing plays a critical role in determining skeletal and dental outcomes. Early treatment enhances skeletal changes, while later treatment is more effective for dental alignment.
