Orthodontic anchoring method and custom appliances affixed to teeth, TADs and/or tooth positioning, moving and stabilization appliances and/or orthodontic auxiliaries. Each appliance has mechanical fasteners structured to secure segments of a curable flexible resin rope called a flex fit module (FFM). The FFM is moldable and adaptable to the oral cavity between mechanical fasteners in an uncured first mode where it is cut to length, positioned around the anatomy of the mouth and attached to clamps or fasteners and/or flex fit wafers FFW(s) at each or one end. Each fastener has a clamp or fastener attached to orthodontic auxiliaries, orthodontic appliances or onto a TAD for anchorage purposes. One end of this custom appliance is usually attached via a clamp or fastener manufactured as part of a bracket or band to a tooth. The other end is connected to an appliance, tad, flex fit wafer or auxiliary. Once connected together the system is cured and becomes a solid entity ready to accept orthodontic forces.
