Effectiveness of invisalign treatment on open bite correction

Abstract

Background: Open bite is a common orthodontic malocclusion that can have functional and aesthetic implications. Traditional orthodontic treatments have been used to correct open bites, but the effectiveness of Invisalign, a clear aligner therapy, in open bite correction remains a topic of interest. Materials and Methods: A retrospective analysis was conducted on a cohort of 50 patients with open bites who underwent Invisalign treatment. Pre-treatment and post-treatment records, including cephalometric radiographs, dental models, and clinical photographs, were assessed. The open bite was defined as a negative overbite greater than 2 mm. Treatment duration, number of aligners used, and patient compliance were also recorded. Statistical analysis, including paired t-tests and subjective patient feedback, was employed to evaluate the treatment outcomes. Results: The mean pre-treatment open bite was -3.5 mm (SD = 1.2), and the mean treatment duration was 18 months (SD = 2.5). On average, patients received 24 sets of aligners (SD = 4.1) during the treatment. Post-treatment evaluation showed that the mean overbite improved to + 1.5 mm (SD = 0.8), indicating successful open bite correction. The paired t-test revealed a statistically significant difference between pre-treatment and post-treatment open bite measurements (P < 0.001). Patient satisfaction was high, with 90% of participants reporting improved aesthetics and comfort. Conclusion: Invisalign treatment demonstrates effectiveness in correcting open bites, with statistically significant improvements in overbite measurements.
