Drs. Roth and Cetlin both recommend the use of Asher style facebows in their treatment philosophies. The AB100 facebow is the Asher style facebow of choice for intrusion and retraction. With a high-pull cap, it retracts and intrudes; with a cervical strap, it simply retracts. The bow is hooked to the archwire, mesial to the cuspid against a keyhole loop or a hook attached to the wire.
The OKC AB100 Asher style facebow is designed for use on the maxillary arch.
It features a short outerbow for use with high pull straps or cervical neckpads.
Attach the facebow to your choice of force modules and cushion.
