Benefits of technology

"The present invention provides a self-ligating orthodontic bracket that can be selected for its exterior color, which can be different than the typical metallic color. The bracket has a clip that can be opened and closed to access the archwire slot. The clip has a base material and a coating that can change the aesthetic characteristics of the base material. The base material can be made of various materials and the coating can be applied using different processes. The surface of the base material can be treated to enhance the attachment of the coating. The clip can also be made using a polymeric material and reinforcing fiber for added strength. The technical effects of the invention include improved aesthetics, better attachment, and increased strength of the orthodontic bracket."

Problems solved by technology

However, metallic materials can be cosmetically undesirable because they do not match the color of the patient's teeth, and thus the resulting brackets are very noticeable.

Embodiment Construction

[0032]FIGS. 1-3 illustrate self-ligating orthodontic brackets 10 having a body 12, a mounting pad 14, a lateral insert 16, and a clip 18. Only the bracket of FIG. 1 will be described below, but a substantial portion of the following description generally applies to any of the brackets.

[0033] The mounting pad 14 includes a lingual surface 15 adapted to be connected to a labial surface of a tooth (not shown). The body 12 includes a lingual surface that is connected to a labial surface of the mounting pad 14. The body 12 defines gingival and occlusal directions and mesial and distal directions, as in known in the art. The body 12 includes two gingival tie wings 20 extending from the body 12 in the gingival direction and two occlusal tie wings 22 extending from the body 12 in the occlusal direction. The body 12 and the mounting pad 14 of the illustrated bracket 10 are made from a ceramic material (e.g., polycrystalline alumina) and are integrally formed with each other. Alternatively, ...

Abstract

An orthodontic bracket comprising a body having an archwire slot and adapted to be secured to a tooth, and a clip coupled to the body and movable between an open position, permitting access to the archwire slot, and a closed position, inhibiting access to the archwire slot. The clip comprises a base material having recesses formed by laser-ablation, and a coating formed over at least a portion of the base material and over at least one of the recesses.

Description

RELATED APPLICATIONS [0001] This patent application claims priority to U.S. Provisional Patent Application No. 60 / 909,609, filed Apr. 2, 2007, and is a continuation-in-part of and claims priority to U.S. patent application Ser. No. 10 / 592,184, filed on Sep. 8, 2006, which claims priority to International Application No. PCT / CA2005 / 000366, filed on Mar. 8, 2005, which claims priority to U.S. Provisional Application No. 60 / 551,281, filed on Mar. 8, 2004, the entire contents of all of which are hereby incorporated by reference.FIELD OF THE INVENTION [0002] The present invention relates to orthodontic brackets and, more particularly, to orthodontic brackets that are designed to have a surface color that blends into the patient's teeth so that the bracket is less noticeable. BACKGROUND OF THE INVENTION [0003] According to established orthodontic techniques, it is well known to attach an orthodontic bracket to a patient's tooth. The bracket provides a location for attaching an archwire an...
