Long-term Outcomes of Traditional Braces versus Invisalign in Orthodontic Treatment

Abstract

ABSTRACT Objective: This research targets to compare the longstanding outcomes of traditional braces versus Invisalign in orthodontic treatment, focusing on dental alignment, occlusal stability, patient satisfaction, and treatment duration. Methods: A retrospective cohort research with 200 subjects was piloted. One hundred subjects received traditional braces, while the other 100 received Invisalign. Dental models, cephalometric radiographs, and intraoral photographs were obtained at baseline, post-treatment, and at 1, 2, and 5 years follow-up. Patient satisfaction surveys were administered at each follow-up visit. Results: Both traditional braces and Invisalign effectively improved dental alignment and occlusal stability over the 5-year follow-up period. Patient satisfaction scores were consistently higher in the Invisalign group compared to the traditional braces group. However, there were no significant differences in treatment duration between the two groups. Conclusion: Invisalign may offer comparable or superior longstanding outcomes compared to traditional braces in orthodontic treatment, with higher patient satisfaction levels. These findings support the use of Invisalign as a viable alternative to traditional braces, particularly for subjects seeking esthetic and convenient orthodontic solutions.
