Frictionless Mechanics is technique in Orthodontics used for retraction of teeth during space closure. Frictionless mechanics involves use of loops and segmental mechanics which help in reducing friction. One of the major advantage of Frictionless mechanics is that a known force system is delivered to the teeth because there is no dissipation of force by friction. This book provides indepth knowledge of segmental mechanics and the springs and appliances used.
