Abstract

A dental mouthpiece is provided that may be attached to a high-suction dental adapter for the purpose of assisting the dental staff during dental procedures through chair-side, hands-free suction, and isolation. Such a mouthpiece may comprise a main body portion, a cheek retractor portion, and a suction connector portion. In an embodiment, the main body portion, cheek retractor portion, and suction connector portion may be molded in one piece, preferably by injection molding. The main body portion has an anterior wall inside the curve and a posterior wall outside the curve, and an at least one connector connecting the anterior wall and the posterior wall. The main body portion has an anterior intervening wall and the posterior intervening wall in between the anterior and posterior walls. The anterior intervening wall and the posterior intervening walls have alternating crests and troughs.

Claims (49)

1. A mouthpiece comprising:

a main body portion comprising:

a first wall that includes one or more edges,

a second wall set at a distance from the first wall, wherein the first wall and the second wall define an interior space that corresponds to the distance between the first wall and the second wall; and

at least one intervening wall that includes a span protruding from the one or more edges of the first wall, wherein the span is defined by a ridged edge that includes a plurality of ridges extending different distances at least partially across the distance between the first wall and the second wall;

a suction connector portion extending from a first end of the main body portion, wherein the suction connector portion includes an evacuation conduit opening into the interior space of the main body portion; and

a cheek retractor portion connected to a second end of the main body portion.

2. The mouthpiece of claim 1 wherein the main body portion further includes a neck that extends from the second end of the main body portion, the cheek retractor portion being connected to the neck of the main body portion, and wherein a width of the cheek retractor portion is greater than a width of the neck.

3. The mouthpiece of claim 1 , wherein the first wall has a shape defined by the one or more edges, and wherein the second wall has a shape corresponding to the shape of the first wall.

4. The mouthpiece of claim 1 , wherein the first wall has a shape that is different from a shape of the second wall.

5. The mouthpiece of claim 1 , wherein the plurality of ridges includes alternating crests and troughs.

6. The mouthpiece of claim 5 , wherein the alternating crests include at least one flat crest.

7. The mouthpiece of claim 5 , wherein the alternating troughs include at least one semi-circular cutout trough.

8. The mouthpiece of claim 1 , wherein the main body portion further includes one or more perforations in one or more of the first wall or the second wall, the perforations opening into the interior space.

9. The mouthpiece of claim 8 , wherein the perforations are located along a perimeter of one or more of the first wall or the second wall.

10. The mouthpiece of claim 8 , wherein the main body portion further includes a neck that extends from the second end of the main body portion, and wherein the perforations are located along one or more sides of the neck.

11. The mouthpiece of claim 1 , further comprising a bite block attached to an outside of the suction connector portion at the first end of the main body portion, wherein the bite block does not obstruct the opening into the interior space.

12. The mouthpiece of claim 1 , wherein the suction connector portion comprises a cutout in a shape corresponding to a shape of a protrusion of a vacuum adapter, the cutout configured to interlock with the protrusion of the vacuum adapter.

13. The mouthpiece of claim 1 , wherein the suction connector portion includes an internal stop configured to assist with sliding an adapter to a predetermined depth.

14. The mouthpiece of claim 1 , further comprising at least one connector that connects the first wall to the second wall.

15. The mouthpiece of claim 14 , wherein the connector includes a wall that extends within the interior space along a longitudinal axis of the main body portion.

16. The mouthpiece of claim 14 , wherein the main body portion further includes a neck that extends from the second end of the main body portion, and wherein the connector extends through the neck at the second end of the main body portion.

17. The mouthpiece of claim 1 , wherein the main body portion is formed of a flexible material that allows for the first wall to be pulled away from the second wall.

18. The mouthpiece of claim 1 , wherein the main body portion is formed of a material that includes silicone, and wherein the material is at least translucent.

19. The mouthpiece of claim 1 , further comprising a bridge structure that includes one or more protrusions protruding from an interior surface of one of the first wall or the second wall within the interior space.

20. A mouthpiece comprising:

a main body portion comprising:

a first wall that includes two edges,

a second wall set at a distance from the first wall, wherein the first wall and the second wall define an interior space that corresponds to the distance between the first wall and the second wall;

wherein the first wall is configured at the two edges to have a ridged configuration with a plurality of ridges extending different distances partially across the distance between the first wall and the second wall, the two edges of the first wall being unconnected to the second wall, the plurality of ridges forming an open-meshed configuration between the first and second walls to allow for suction of fluids from a patient's mouth into the interior space between the first and second walls; and

a suction connector portion extending from a first end of the main body portion, wherein the suction connector portion includes an evacuation conduit opening into the interior space of the main body portion; and

a cheek retractor portion connected to a second end of the main body portion.

21. The mouthpiece of claim 20 , wherein the cheek retractor portion is connected to a neck of the main body portion, wherein the neck extends from the second end of the main body portion.

22. The mouthpiece of claim 21 , wherein a width of the cheek retractor portion is greater than a width of the neck.

23. A mouthpiece comprising:

a main body portion comprising:

a first wall that includes two edges,

a second wall set at a distance from the first wall, wherein the first wall and the second wall define an interior space that corresponds to the distance between the first wall and the second wall;

wherein the first wall is configured at the two edges to have a ridged configuration with a plurality of ridges extending different distances partially across the distance between the first wall and the second wall, the two edges of the first wall being unconnected to the second wall, the plurality of ridges forming an open-meshed configuration between the first and second walls to allow for suction of fluids from a patient's mouth into the interior space between the first and second walls; and

a suction connector portion extending from a first end of the main body portion, wherein the suction connector portion includes an evacuation conduit opening into the interior space of the main body portion; and

a neck that extends from the second end of the main body portion.

24. The mouthpiece of claim 23 , wherein the main body portion further includes a plurality of perforations that open into the interior space, the plurality of perforations being located in the first wall and in the neck.

25. The mouthpiece of claim 23 , further comprising a connector wall that connects the first wall to the second wall, the connector wall extending within the interior space along a longitudinal axis of the main body portion.

26. The mouthpiece of claim 25 , wherein the connector wall extends through the neck at the second end of the main body portion.

27. The mouthpiece of claim 26 , wherein the main body portion is formed of a flexible material that allows for the two edges of the first wall to be pulled away from the second wall.
