Dental aligner devices having snap-on connectors
A system for producing corrective movement in a subject's teeth includes a dental aligner device having one or more through-holes and one or more connectors fixed to the subject's teeth. The connectors can snap into the through-holes when the dental aligner is worn on the subject's teeth.
1 . A device for producing corrective movement in a subject's teeth, the device comprising:
a dental aligner configured to be worn on a subject's teeth, the dental aligner comprising:
a shell portion having an outer surface and an inner surface, wherein at least a portion of the inner surface is configured to contact the subject's tooth; and
one or more through-holes passing from the outer surface to the inner surface of the shell portion of the dental device.
2 . The device of claim 1 , wherein the through-hole is configured to mate with a connector.
3 . A system for producing corrective movement in a subject's teeth, comprising:
a dental aligner device having one or more through-holes, wherein the dental aligner device is configured to be worn on the subject's teeth; and
one or more connectors, wherein the connector is configured to engage the through-hole when the dental aligner is worn on the subject's teeth.
4 . The system of claim 3 , wherein the one or more connectors include one or more of posts, nodules, and bumps.
5 . The system of claim 3 , wherein the dental aligner contacts the subject's teeth when the connector is engaged with the through-hole in the dental aligner.
6 . The system of claim 3 , wherein the dental aligner is fabricated by one or more of vacuum forming, milling, stereo lithography, laser machining, molding, and CNC based manufacturing.
7 . The system of claim 3 , wherein the dental aligner comprises:
a shell portion having an outer surface and an inner surface to be in contact with the subject's tooth;
a bottom portion to be placed near the gingival line of the subject's tooth; and
a tip portion on the opposite side of the bottom portion.
8 . The system of claim 7 , wherein the through-hole of the dental aligner device passes through the bottom portion or the tip portion.
9 . The system of claim 3 , wherein the connector is configured to be secured to a subject's tooth.
10 . A system for producing a snap-on dental aligner for dental treatment, comprising:
a guide to indicate the locations of through-holes to be formed in a dental aligner;
a positioner to position a hole-maker with respect to the dental aligner based on the indication of the guide; and
a hole-maker to produce through-holes in the dental aligner at the positions indicated by the guide to produce the snap-on dental aligner.
11 . The system of claim 10 , wherein the guide comprises a computer to store the locations of through-holes to be formed in a dental aligner.
12 . The system of claim 11 , wherein the computer is further configured to store locations of one or more connectors to be secured to the subject's teeth, so that the one or more connectors engage the through-holes when the dental aligner is worn on the subject's teeth.
13 . The system of claim 10 , wherein the hole-maker is configured to drill through-holes in the dental aligner.
14 . The system of claim 10 , wherein the hole-maker comprises a mechanical drill bit or a laser.
15 . A method for moving a subject's teeth in a dental treatment, comprising:
fabricating a dental aligner to be worn on the subject's teeth;
producing one or more through-holes in the dental aligner;
fixing one or more connectors on the subject's teeth to engage the through-holes; and
engaging the one or more connectors on the subject's teeth with the through-holes of the dental aligner to secure the dental aligner on the subject's teeth.
16 . The method of claims 15 , further comprising fixing the one or more connectors on the subject's teeth at locations in registration with the through-holes when the dental aligner is worn on the subject's teeth.
17 . The method of claim 16 , wherein the connector comprises a pre-formed connector.
18 . The method of claim 16 , wherein the connector comprises an adhesive or a UV cross-linkable polymer.
19 . The method of claim 16 , wherein the one or more connectors include one or more of protrusions, nodules, and bumps.
20 . The method of claim 15 , further comprising securing the dental aligner against the subject's teeth to engage the connectors secured on the subject's teeth into the through-holes of the dental aligner.
21 . The method of claim 15 , further comprising fabricating the dental aligner device by one or more of vacuum forming, milling, stereo lithography, laser machining, and molding.
22 . The method of claim 15 , further comprising drilling the one or more through-holes in the dental aligners.
