Effects of Bracket Base Design and Pre-Coated Adhesive Type on Adhesive Thickness
Abstract
Objective: To compare the consistency of the adhesive thickness achieved when using different bracket base designs, and to compare the adhesive thickness measurements when using different pre-coated adhesive types. Materials and Methods: Teeth models were designed and duplicated with a 3D printer. 3Shape Orthodontic Scanner and Ortho Analyzer software were used for the initial measurements without the brackets bonded and final measurements with the brackets bonded. Two different bracket base designs were used: Victory Series Low Profile brackets and Unitek Miniature Twin brackets. Two different pre-coated adhesive types were used: Flash-Free and APC II. Results: 3M Unitek Miniature Twin brackets achieved more consistent adhesive thickness compared to the Victory Series Low Profile brackets for mandibular 1st premolar brackets. Placing brackets with Flash-Free adhesive achieved thicker adhesive thickness compared to APC II adhesive. Conclusions: It is important to annotate the specific bracket types and include the pre-coated adhesive types to prevent mixing different bracket systems within the same arch. The differences in the values from this study were statistically significant, and further studies are needed to determine the clinical significance of the outcome and how it will impact the eventual teeth alignment.
