Abstract

Described herein are systems and methods for providing personalized oral irrigation. One variation of a system for personalized oral irrigation comprises a fluid reservoir and a customized oral insert in fluid communication with the fluid reservoir. The oral insert comprises an arrangement of fluid openings positioned based on the individual oral or dental structures of a user's teeth to provide a customized fluid flow over the user's teeth. Also described herein are methods for generating an arrangement of fluid openings in a customized oral insert.

Claims (24)

1. An oral insert, comprising:

a first channel; and

a first plurality of fluid openings located within the first channel, wherein a fluid opening of the first plurality of fluid openings is adapted to be positioned at an angle of 0° to 90° relative to a long axis of a tooth associated with a user and adapted to be located within 0 mm to 10 mm from interproximal regions on either side of the tooth, wherein an arrangement of the fluid openings is adapted to correspond to a location of gingival margins, the interproximal regions, incisal edges, and/or contours of an occlusal, facial, lingual, mesial and/or distal surfaces of teeth associated with the user, wherein a corresponding shape associated with a first fluid opening of the first plurality of fluid openings directed to a first interproximal region is V-shaped, wherein the first fluid opening having a first lobe and a second lobe, wherein a lobe angle between the first lobe and the second lobe corresponds to a curvature of a gingival margin of one or more teeth associated with the user.

2. The oral insert of claim 1 , wherein the first plurality of fluid openings is for mandibular teeth and/or maxillary teeth associated with the user.

3. The oral insert of claim 1 , further comprising:

a second channel; and

a second plurality of fluid openings located within the second channel, wherein the second plurality of fluid openings is adapted to be directed towards mandibular teeth and/or maxillary teeth associated with the user.

4. The oral insert of claim 1 , wherein a shape of a fluid opening of the first plurality of fluid openings is a circle, a line, a curve, a multi-linear radial shape, a multi-lobular radial shape, a Y-shape, or an irregular shape that is tailored according to a dental geometry of the user.

5. The oral insert of claim 1 , further comprising a plurality of manifolds.

6. The oral insert of claim 5 , wherein the plurality of manifolds are configured to receive a pulsing flow of liquid from a fluid supply.

7. The oral insert of claim 6 , wherein the pulsing flow of liquid is received at a rate between 1 Hz to 25 Hz.

8. The oral insert of claim 7 , wherein the rate is user-adjustable.

9. The oral insert of claim 1 , wherein the first channel includes a first side wall, a second side wall, and a bottom wall that are sized to fit around the teeth associated with the user.

10. The oral insert of claim 1 , wherein the first channel includes one or more alignment features.

11. The oral insert of claim 10 , wherein the one or more alignment features include one or more protrusions, slots, and/or recesses.

12. The oral insert of claim 1 , further comprising one or more shields that are located within the first channel based on one or more missing and/or broken teeth associated with the user.

13. The oral insert of claim 1 , wherein the first plurality of fluid openings include one or more release fluid openings and one or more non-release fluid openings.

14. The oral insert of claim 13 , wherein the one or more non-release fluid openings are configured to irrigate an oral cavity associated with the user.

15. The oral insert of claim 1 , wherein a spacing or distance between a first fluid opening and a second fluid opening corresponds to a distance between interproximal space or a size and shape of the teeth.

16. The oral insert of claim 1 , wherein the oral insert is configured to engage with a handle.

17. The oral insert of claim 1 , further comprising a plurality of fluid jets.

18. The oral insert of claim 17 , wherein the plurality of fluid jets are configured to generate stresses greater than 0.014 psi.

19. The oral insert of claim 17 , wherein the plurality of fluid jets are configured to generate flowrates from 0.3 l/min to 20 l/min.

20. The oral insert of claim 17 , wherein the plurality of fluid jets are configured to generate pressures from 10 psi to 150 psi.
