SIMULTANEOUS RETRACTION AND INTRUSION OF MAXILLARY ANTERIOR TEETH: A REVIEW

Abstract

Simultaneous retraction and intrusion of anterior segment are required in the patients who have deep overbite along with ared incisors. During the retraction of anterior segment, there is some bite deepening, which also requires intrusion. So there are various conventional methods which are used from many last years to achieve simultaneous retraction and intrusion, but these methods require patient compliance and have some undesirable side effects like anchorage loss. With the advent in technology, Orthodontic mini-implants (OMI) broaden the scope of orthodontic therapy by allowing treatment to proceed with little or no anchoring loss and require less patient participation than traditional procedures. Mini implants can be used to offer good anchorage for anterior tooth retraction and intrusion, and they can be inserted in almost any desirable site. There are various conventional methods as well as mini implant supported methods with which simultaneous retraction and intrusion can be achieved. This review article presents the various methods for achieving simultaneous retraction and intrusion of anterior segment either with conventional techniques or with the help of mini implants.
