FRICTION MECHANICM IN ORTHODONTICS; A REVIEW

Abstract

The force that prevents one object from moving while it moves tangentially against another is called friction. Different forces are created when two surfaces in contact slide against one another. In order to achieve the correct tooth movements, orthodontics must effectively manage friction, which presents a difficulty, particularly when it comes to sliding mechanics. Friction is affected by a number of things, including ligation, brackets, and archwires. Because the critical contact angle is reached with a smaller tip in the bracket, the friction will increase with the wire's diameter. Ti brackets are preferred in a comparable manner as those made of stainless steel. When compared to stainless steel brackets, ceramic brackets generate almost twice as much friction.
