Forces generated with the use of intrusion arches in orthodontics – A review of literature

In routine orthodontic practice, Class II malocclusions are the most customary treated cases. The cardinal objective and radical challenge of Class II treatment is the correction of deep overbite. Correction of deep overbite should be carried out prior to retraction of teeth. Various treatment protocols are used for correction of deep overbite, in which intrusion arches are more elementary to use for correcting deep bite by true intrusion or by pseudo-intrusion. This review paper contains various intrusion arches and related studies along with the key functions which are sketched out in the form of table. Individual forces produced by intrusion arches on teeth for all tooth movements are also categorized and tabulated.
