Problems solved by technology

[0013] Aligners manufactured by hand or by thermoforming on a male mold are uncomfortable for many patients and irritate the patient's gums and / or tongue to the point of soft tissue inflammation and possible bleeding
This discomfort is usually caused by the aligner not being precisely trimmed to the patient's gingival margin
Imprecision in trimming is often caused by the smallest dimensions of the trimming tool especially on the anterior lingual side where the aligner intervenes in the tongue

Embodiment Construction

[0091] In general, an embodiment of the invention includes a direct-manufactured orthodontic appliance capable of moving teeth according to a predetermined treatment plan, such as image 3 and 4 shown. In particular, the orthodontic appliance can move one or more teeth from one orientation to another, which promotes the overall displacement of the teeth towards their final orthodontically correct and aesthetically desired position. In one embodiment of the invention, orthodontic treatment may be accomplished using a series of individual orthodontic appliances. Thus, each appliance in the series can move one or more teeth by a specified amount. Cumulatively, these individual volumes can accomplish a complete treatment of the patient's malocclusion.

[0092] By way of example only, in one embodiment the orthodontic appliance may include an aligner. These aligners are similar to those used in the prior art, but the difference lies in the way the aligners are manufactured, and...

Abstract

A method for direct fabrication of an orthodontic device having tooth-fitting cavities, such as an aligner, using layer-by-layer printing of a single or multiple polymeric materials. The cavities of the appliance are defined by the boundaries of the multiple layers, encapsulating up to fourteen teeth of a patient, and shaped to apply a load to at least one tooth that is sufficient to cause movement of the tooth, and remodeling of the adjacent bone. A series of such appliances may be used to treat malocclusion of teeth, each directly manufactured appliance used in series to incrementally move one or more teeth from initial positions toward a desired final position. The appliance may be fabricated with a variety of disclosed materials, and may include auxiliary features for interaction with other orthodontic elements.

Description

[0001] related application [0002] This application claims priority to US Serial No. 61 / 546,554, filed October 12, 2011, the entire contents of which are hereby incorporated by reference. technical field [0003] This invention relates to orthodontic appliances and in particular to orthodontic aligners. Background technique [0004] In traditional orthodontic treatment, an orthodontist or assistant secures orthodontic appliances, such as orthodontic brackets, to a patient's teeth and incorporates archwires into slots in each bracket. The archwire applies the corrective force, forcing the teeth to move to the correct orthodontic position. The archwires are held in each bracket slot with traditional ligatures, such as small elastic O-rings or fine wire. Due to the difficulty encountered in applying individual ligatures to each bracket, self-ligating orthodontic brackets have been developed that eliminate the need for reliance on removable locks or slides to hold the archwir...
