FRICTIONLESS MECHANICS in orthodontics tooth movement.pptx
The key advantages of frictionless mechanics using loops over traditional friction-based sliding mechanics are that it allows for more precise control and monitoring of optimal continuous forces over longer durations. Various loop designs and factors influencing tooth movement during space closure using frictionless mechanics are explored.
This article discusses various techniques for closing extraction spaces using frictionless mechanics in orthodontic treatment. It describes space closure loops and systems that apply forces through bending archwire segments rather than tooth movement along a continuous archwire. These include en masse retraction using headgear, the Broussard two-force system, the Bimetric arch, Bull loops ...
PDF Comparison of Frictionless Mechanic with 2 Different Bracket Design
Use of a frictionless system accomplishes space closure by means of buccal sectional closing loops or retraction springs, making it possible to apply predetermined and precise forces which can meet the biomechanical requirements for a planned tooth movement .
Such details provide a deeper understanding and appreciation for Adjustable Closure With Frictionless Movement.
Hence, in this systematic review we aim to compare the different force delivery systems for space closure during orthodontic treatment in terms of different outcomes: rate of tooth movement , force level, effect on anchorage, periodontal effects, cost efficiency and patient-centred outcomes, using both traditional and network meta-analysis designs.

In spite of the variety of appliance designs, space closure can be performed by means of friction or frictionless mechanics, and each technique has its advantages and disadvantages.
Space Closure Using Frictionless Mechanics
As we can see from the illustration, Adjustable Closure With Frictionless Movement has many fascinating aspects to explore.
Space closure mechanics can either be friction or frictionless . So, optimizing the mechanics in different space closure situation is desired and required, whether the friction or frictionless mechanics is used and the planning of either of them should be based on sound biomechanical principles.
Friction during space closure occurs because the archwire used in orthodontics comes into contact with either the bracket slot or ligature [3]. High frictional forces can hinder tooth movements , thereby causing delays in treatment because it takes longer for teeth to move.
A comprehensive review on loops in orthodontics
Direct and indirect skeletal anchorage was implemented in the friction and frictionless groups, respectively, during anterior segment retraction. The posterior segments were equally restricted from mesial movement in both groups through direct ligation between the mini-screws and the retracted canines.
