Abstract: The invention relates to a method of applying an orthodontic aid to at least one tooth in a row of teeth. A cast of the row of teeth is made by means of molding and counter-molding. The aid is temporarily secured to the cast in the desired position. A deformable layer of material is applied to the cast with aid, and this layer is deformed to conform to the shape of the cast with aid and thus a mold is formed. The mold with aid is positioned on the row of teeth and the bonding agent applied for securing the aid is allowed to harden in a controlled manner. Then the mold is removed, and the aid remains behind, secured to the row of teeth by means of the bonding agent. According to the invention prior to placing the mold with the aid on the row of teeth, an adhesive layer is applied to at least a part of the surface of the mold, that is brought into contact with the row of teeth. This adhesive layer has weaker adhesive strength than the bonding agent for securing the aid to the row of teeth.

Abstract: A method of applying an orthodontic wire which is affixed to at least one of a row of teeth with an adhesive. A cast is made of the row of teeth. The wire is brought into the desired shape on the cast, and temporarily secured in position. Over the cast with wire, a layer of permanently resilient material is applied, which is deformed to conform to the shape of the cast to form a mold. The mold with the wire embedded therein is removed from the mold. The wire is temporarily removed from the mold, the mold is provided with perforations at the desired locations, which correspond to the shape and dimensions of the adhesive receiving places, the wire is re-positioned in the mold, and the perforations are filled with adhesive. The mold with the wire embedded therein and adhesive applied is then placed on, and over, the row of teeth and pressed into contact with them.
