The use of mini-implants in en masse retraction for the treatment of bimaxillary dentoalveolar protrusion

Abstract

This case report describes the treatment of a 22-year-old girl who had incompetent lips with severe bimaxillary dentoalveolar protrusion. The treatment of choice for such patients is usually extraction of four first premolars and retraction of the anterior teeth. To maintain the extraction space, maximum anchorage is required. Mini-implants were used to provide maximum anchorage for obtaining a good facial profile. Keywords: Mini-implants, Dentoalveolar, Protrusion, En masse, Anchorage, Spider Screws
