Abstract

This study was designed to understand and evaluate the choice between friction and frictionless mechanics in extraction space closure. The orthodontics case sheets were evaluated to identify extraction cases. After examining 428 case sample tabulation of choice between friction and frictionless mechanics were examined. More female patients underwent orthodontic treatment. More cases were treated by friction mechanics rather than by frictionless mechanics. Only 55 cases of the whole were treated by loops for retraction and space closure. More orthodontists preferred retraction using friction mechanics which can be attributed to factors like being treated by faster mechanics, less cost and lesser demanding skill of clinician. The chair side time required is reduced
