A preliminary report of a new design of cast metal fixed twin-block appliance.
The present paper describes a cast metal fixed twin-block appliance utilized to correct a Class II malocclusion, which is designed for full-time wear. The object of the present paper is to achieve rapid functional correction of Class II malocclusions by transmitting favourable occlusal forces to inclined planes which are cemented to the posterior teeth. In the meantime, pre-adjusted fixed edgewise appliances can be placed on the anterior teeth to correct their malpositions. This new functional appliance design may shorten the total treatment duration and reduce the need for patient compliance.
