摘要
The orthodontic appliance for correction of Class II or III malocclusions attaches to the maxillary arch at the first molar and to the mandibular arch on the archwire in the cuspid or bicuspid area, and applies a low continuous force through the use of two plunger piston type devices, whether the mouth is open or closed. Dual acting piston cylinders are connected together , with first and second piston connecting rods extending in opposing directions fro m the piston cylinders. A first mounting element is provided at the exterior end o f the first piston connecting rod for mounting the first piston connecting rod to at least one of the maxillary teeth, and a second mounting element is provided at the exterior end of the second piston connecting rod for mounting the second piston connecting rod to at least one of the mandibular teeth, for providing a continuous biasing force between the maxillary and mandibular teeth for treatment of malocclusions.
