ORTHODONTIC APPLIANCE WITH LOW PROFILE CLIP |
摘要 |
<p>Provided is an improved self-ligating orthodontic appliance and methods of assembling the same. The improved orthodontic appliance uses at least one resilient clip to releasably couple an archwire to the body, where a portion of the clip is rigidly coupled to the appliance body in a position and orientation that minimizes the overall profile of the appliance. The appliance is assembled by combining a press fit coupling between the clip and appliance body with an interference fit coupling between the clip and retaining structure located on the body. Advantages include a greater freedom to select a bonding pad location, lower bracket profile, decreased engagement force, enhanced clip fatigue life, and ease of assembly.</p> |
