The FR Crozat Appliances eliminate certain compliance problems, e.g. those resulting from uncooperative or careless patients. These appliance utilize the Wilson 3D® modular system* to attach the Crozat to bands cemented on the molars. All the regular Crozat additions and auxiliaries (as well as other 3D® components) can be integrated into this design -- and can be used even in conjunction with the Straight Wire Technique. The #3810 is an upper and #3820 is the lower.
