Evaluation and comparison of bracket slot dimensions in lingual bracket systems: An in vitro study

ConclusionsActual slot size and shape of commercially available brackets are larger or smaller from the actual prescribed value within a bracket series. Slot geometry and the standard of bracket finish varies between the brackets of different groups. Clinicians should be aware that there may be a three-dimensional loss of tooth positioning as a result of the inadvertent use of orthodontic brackets with oversized slots prolonging treatment duration and the need of additional wire bending to overcome the inadequacies of the brackets so as to achieve a good finishing.
