Evaluation of the efficacy of sliding mechanisms on round versus rectangular archwires in canine retraction after first premolar extraction in class II malocclusion: a randomized clinical trial
{{output}}
Objective(s): To compare the efficacy of sliding mechanics on a 0.020-inch round posterior segment incorporated into a bi-dimensional archwire (BA) versus conventional rectangular-section archwire (CONV) for maxillary canine retr... ...
