Xbow®

The Xbow® (Crossbow®) Class II Corrector is an alternative to the Herbst Appliance, with the advantage of having more unilateral control in asymmetric Class II cases. It includes a maxillary expansion appliance, making it possible to correct both sagittal and transverse problems. It does not require patient cooperation like the Twin Block, Headgear, or Class II elastics. It does not extrude upper incisors like Class II elastics.

Quote from Dr. Hughes' article:"I have used a variety of Class II correctors over the years—headgear, Jasper Jumpers, Herbst, Flip-lock Herbst, etc. In my experience, nothing can touch the efficiency and effectiveness of the combination of Higgins Xbow® and 3M Forsus Correctors to correct moderate to severe adolescent cases." 

 

Initial

5 months Xbow followed by 11 months braces

Adding mini tubes to the first bicuspids adds options for incisor and canine management. Inserting the "L" pin from the mesial

prevents cheek impingement.
