Abstract

The various embodiments described herein include methods, devices, and systems for customizing dental care. In one aspect, a dental care device is customized for a particular user, including: (1) a support plate having: (a) a first portion configured to be inserted into a mouth; and (b) an attachment mechanism configured to attach the dental care device to a drive assembly; and (2) an elastomer (elastic polymer) portion enclosing the first portion of the plate, the elastomer portion including a plurality of cleaning tips and shaped in accordance with dental details of the particular user.

Claims (43)

1. A method of fabricating a teeth cleaning device customized to a particular user, comprising:

providing a support plate having an attachment tab configured to attach to an external drive mechanism;

providing a mold;

obtaining an electronic 3D dental model of the inside of a particular user's mouth;

generating an upper mold insert customized in accordance with upper teeth and gums based on the electronic 3D dental model of the particular user;

generating a lower mold insert customized in accordance with lower teeth and gums based on the electronic 3D dental model of the particular user, where the upper mold insert is different than the lower mold insert;

placing into the mold the support plate between the upper and lower mold inserts;

injecting an elastomer into the mold to form an intermediary molded device;

removing the intermediary molded device from the mold; and

removing the upper and lower mold inserts from the intermediary molded device to expose the teeth cleaning device comprising upper and lower cleaning portions with the support plate positioned there between.

2. The method of claim 1 , wherein the support plate is molded out of a plastic material that is more rigid than the upper and lower cleaning portions.

3. The method of claim 1 , wherein the upper and lower mold inserts are fabricated via a 3-D printing process.

4. The method of claim 1 , wherein the dental details of the particular user comprise information regarding locations and shapes of the particular user's teeth.

5. The method of claim 1 , wherein the upper and lower cleaning portions include a plurality of cleaning tips formed from apertures in the upper and lower mold inserts.

6. The method of claim 1 , further comprising selecting the mold from a set of molds based on a size of a jaw of the particular user.

7. The method of claim 5 , wherein the dental details of the particular user are used to determine locations of the apertures in the upper and lower mold inserts.

8. The method of claim 7 , wherein the dental details of the particular user comprise information regarding locations and shapes of the particular user's teeth.

9. The method of claim 5 , wherein the plurality of cleaning tips have lengths ranging from 0.5 mm to 6.0 mm.

10. The method of claim 5 , wherein:

each of the plurality of cleaning tips has a first end and a second end; and

a width of each of the plurality of cleaning tip decreases from the first end to the second end.

11. The method of claim 1 , wherein providing the upper and lower mold inserts customized in accordance with dental details of the particular user comprises printing the upper and lower mold inserts in accordance with dental details of the particular user.

12. The method of claim 1 , wherein the elastomer is composed of biocompatible silicone.

13. The method of claim 1 , wherein the upper and lower cleaning portions enclose the support plate.

14. The method of claim 1 , wherein:

the upper and lower mold inserts include one or more apertures; and

the method further comprises fixing the upper and lower mold inserts to the mold by the one or more apertures.

15. The method of claim 1 , wherein:

the lower mold insert includes a first plurality of apertures with a first arrangement; and

the upper mold insert includes a second plurality of apertures with a second arrangement that differs from the first arrangement of the first plurality of apertures.

16. A method of fabricating a teeth cleaning device customized to a particular user, comprising:

3-D printing upper and lower mold inserts in accordance with dental details of the particular user;

placing the upper and lower mold inserts in a mold;

placing a support plate, the upper mold insert, and the lower mold insert in a mold such that the support plate is positioned between the upper and lower mold inserts;

injecting a polymer into the mold to form a molded device; and

removing the upper and lower mold inserts from the molded device to expose the teeth cleaning device comprising upper and lower cleaning portions with the support plate positioned there between.

17. The method of claim 16 , wherein:

the lower mold insert includes a first plurality of apertures with a first arrangement; and

the upper mold insert includes a second plurality of apertures with a second arrangement that differs from the first arrangement of the first plurality of apertures.

18. The method of claim 17 , wherein:

the lower cleaning portion includes a first plurality of cleaning tips formed from the first plurality of apertures of the lower mold insert; and

the upper cleaning portion includes a second plurality of cleaning tips formed from the second plurality of apertures of the upper mold insert.

19. The method of claim 16 , wherein the support plate includes an attachment tab configured to attach to an external drive mechanism.
