Intrusion is a common orthodontic tooth movement which is employed in the cases of deep
bite where anteriors are intruded for correction, or in anterior open bite where posteriors
are intruded to close the bite for correction. The article includes the biomechanics of
Intrusion in Orthodontic treatment and various methods to achieve the Intrusion tooth
movement successfully without causing any deleterious effect to the tooth. It also
containthe types of Intrusion, their indications and contraindications. Use of various fixed
appliances and their modifications to achieve intrusion mechanics is discussed and
reviewed in the article.

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
