Treatment of bimaxillary protrusion with temporary anchorage devices

J Oral Sci. 2018;60(2):316-319. doi: 10.2334/josnusd.17-0152.

Abstract

For treatment of severe bimaxillary protrusion in adults, a condition known to be among the most difficult to manage, both the maxillary and mandibular anterior teeth must be fully retracted using all the extraction space available. This article reports the treatment of an adult with severe high-angle bimaxillary protrusion. To correct the protrusion of the anterior teeth, orthodontic anchor screws (OASs) were used to provide absolute anchorage during anterior retraction. Acceptable occlusion, facial profile, and balance were achieved. OASs appear to be very useful for treatment of severe bimaxillary protrusion in adults.

Keywords: anchorage loss; bimaxillary protrusion; orthodontic anchor screw.
