ABSTRACT:
Elastomeric, orthodontic, tension-applying apparatus, and a method for molding the same to yield a device characterized by highly uniform eleasticity properties. In the final molded product, plural endless loops are interconnected, in a chain-like fashion, by integral tensioning structure, with each loop joined to the side of an elongated carrier prong through an individual isthmus. These isthmuses result, during the molding process, from individual flow-gating which is provided for each loop, and such gating is key to ultimate elasticity uniformity.
