Background: This review aims to discuss various canine retraction techniques using frictionless mechanics. Methods: Between 1930 and February 2022, searches were conducted about fixed orthodontic appliances in databases, including PubMed Central, Science Direct, Wiley Online Library, the Cochrane Textbooks, Google Scholar, Research Gate, manual searching. Results: After removing duplicate artic...

In the case shown here, skeletal plates in the zygomatic buttress allowed us to transmit orthodontic forces from the molars to the maxilla for posterior vertical intrusion. This article will examine the orthodontic mechanics needed to control the ratio of the moment of couple (MC) to the moment of force (MF) and the load-deflection ratio, working within the range, strength, and formability of t...
