Abstract

Aim and Objective: The purpose of this study was to investigate magnitude and direction of forces generated in the maxillary anterior region with engagement of arch wires into slots of conventional and self-ligating brackets during initial leveling and alignment stage of orthodontic treatment.
Materials and Method: Three-dimensional models of Damon Q (Ormco, Glendora, California) and Mini 2000 (Ormco, Glendora, USA) brackets (upper 3 to 3) were modeled using micro computed tomography. A 3D orthodontic model was designed to replicate moderate crowding in the dental arch with all supporting structures. The simulated malocclusion represented a maxillary central incisor displaced 3.8 mm lingually and 3.16 mm gingivally. 0.014” Copper-Nickel-titanium (CuNiTi) wire was engaged in Damon Q and Mini 2000 brackets for alignment on the same model and force magnitude and stresses generated were measured with ANSYS Mechanical R19.0 software.
Results: Damon Q brackets delivered light continuous forces when compared to Mini 2000 brackets. Stresses generated on teeth and periodontal ligament (PDL) are lesser with Damon Q as compared to Mini 2000 brackets. Tooth deformation was more with Damon Q brackets as compared to Mini 2000 brackets.
Conclusion: Adult orthodontic cases, especially with compromised periodontal health, can be treated more efficiently with minimum patient discomfort and complications such as root resorption with Damon Q brackets and 0.014” CuNiTi wires.
