Progress in the study of en-masse retraction of maxillary anterior teeth in patients with tooth extraction
Abstract:Extraction is a common method to relieve maxillary protrusion and improve facial profile in orthodontic treatment. The en-masse retraction of anterior teeth under the control of maximum Anchorage is the key to control the torque of incisors and overbite. It is also the key and a difficult problem of tooth extraction and orthodontic treatment. The application of different arch wires to the en-masse anterior teeth retraction under implant Anchorage control is a hot issue in recent years. In this paper, the research progress of the en masse anterior teeth retraction at home and abroad in recent years is reviewed.
