Evaluating orthodontic bracket slot dimensions and morphology: A narrative review

Mohammed Nahidh et al. J Orthod Sci. .

Abstract

The current article aims to review the previous studies that measure the orthodontic bracket slot dimensions and geometry. Searches in different databases, including PubMed Central, Science Direct, Wiley Online Library, the Cochrane Library, Textbooks, Google Scholar, and Research Gate, in addition to a manual search, were performed about the methods of assessing orthodontic bracket slot dimension up to March 2023. The irrelevant and duplicate studies were eliminated, leaving 35 studies for this narrative review. The findings indicate that the slots are oversized with diverging walls in most studies. Manufacturers must respect the standards during manufacturing brackets and adhere to the actual dimensions and tolerance values.

Keywords: Dimensions; geometry; orthodontic bracket slot; play; torque.
