Assessing Cephalometric Changes in Deep Bite Correction: An Analysis of Class II Division 1 Orthodontic Patients Treated with the Reverse Curve of Spee Archwire.

OBJECTIVE

This study aimed to analyze cephalometric changes associated with deep bite correction using the Reverse Curve of Spee (RCS) archwire in class II division 1orthodontic patients.

METHODS

A total of 168 orthodontic patients (aged 12-25 years) with diagnosed deep bite malocclusion underwent deep bite correction using RCS archwires between January 2019 and December 2020. Cephalometric radiographs were taken at various time points to assess skeletal and dental changes. RCS archwires were customized based on individual treatment plans, and a structured follow-up schedule was implemented to monitor progress and make necessary adjustments.

RESULTS

The study analyzed cephalometric changes in the entire cohort, considering age and gender subgroups. Preliminary findings indicate significant improvements in overbite reduction and dental alignment. Subgroup analyze reveal potential age-related variations in treatment response, with younger patients demonstrating slightly more favorable outcomes (Changes in overbite: -2.0 mm, P = 0.05). Gender differences in cephalometric changes are also observed, suggesting the need for gender-specific considerations in deep bite correction (Changes in dental alignment: -1.5 mm in males, -1.2 mm in females, P = 0.03).

CONCLUSION

This retrospective analysis provides valuable insights into the cephalometric changes associated with RCS archwire intervention for deep bite correction.
