Abstract: A self-ligating orthodontic bracket assembly with selectively removable self-ligation features is configured to provide a low profile to minimize labial-lingual prominence. A clip is configured to snap into the base of the bracket and close over the archwire slot to retain the archwire in the slot. The clip is easily moved to an open position when the archwire is changed out during routine treatment. The clip includes spaced apart arms that, along with the bracket tie-wings, straddle the most outwardly prominent site on the crown of the tooth thereby minimizing labial-lingual profile. The self-ligation capability is achieved without any increase in occlusal-gingival height or measial-distal width of the orthodontic bracket.

Abstract: An orthodontic bracket is provided to assist in aligning with the occlusal plane in the tooth long axis of a patient's tooth when mounting the bracket on the tooth. The orthodontic bracket has a tie wing recess having a rhomboidal configuration and an archwire slot recess also having a rhomboidal configuration. Vertical sight lines are used to assist in aligning with the tooth long axis and the horizontal sight lines are used to assist in aligning with the occlusal plane. The archwire slot recess also reduces friction between the archwire slot and the archwire.

Abstract: An orthodontic appliance for use in the mouth which includes an annealing process to provide a marking area. A laser is used to surface anneal an orthodontic appliance, such as an orthodontic bracket, for identification purposes and to withstand a number of recycling processes for sterilization purposes. The surface annealing process does not remelt the marking area and is an advantage over the prior art in that the marking area is not rough or weakened by remelting the structure.
