Abstract

Apparatuses, including sleeves, intraoral scanning systems to use these sleeves, and methods of using the sleeve.

First claim

What is claimed is:

1. A sleeve for an intraoral scanner, the sleeve comprising:
an elongate and hollow body having a distal end and a proximal end, wherein the distal end is tapered and closed and the proximal end is open to receive an intraoral scanner;
a window opening on a lateral side of the distal end;
a transparent cover over the window opening; and
a ramp formed integrally within the elongate and hollow body, the ramp including a plurality of ribs extending in a proximal to distal direction and having a distal facing ramp angle and a proximal facing ramp angle greater than the distal facing ramp angle, and wherein the ramp is positioned within the hollow body proximal to the window opening, and configured to guide a distal end of the intraoral scanner away from the window opening as the intraoral scanner is inserted into the sleeve.

2. The sleeve of claim 1 , further comprising a foam at least partially circumferentially around the window opening within the hollow body, wherein the transparent cover is secured against the foam.

3. The sleeve of claim 1 , further comprising one or more projections configured to impinge into a field of view of the intraoral scanner from a periphery of the window into the window opening when the intraoral scanner is engaged with the sleeve.

4. The sleeve of claim 1 , further comprising a sleeve extension extending from the proximal end of the elongate and hollow body.

5. The sleeve of claim 4 , wherein the sleeve extension is configured to invert over itself when pulled distally.

6. The sleeve of claim 1 wherein the sleeve is formed of a polyethylene material.

7. The sleeve of claim 1 , further comprising an adhesive seal around the window opening sealing the transparent cover to the window opening.

8. The sleeve of claim 1 , further comprising a sealing frame coupled to an outside of the elongate and hollow body so that the transparent cover is sandwiched between a periphery of the window opening and a sealing frame window opening.

9. The sleeve of claim 8 , wherein the sealing frame is coupled to the elongate and hollow body by one or more snap fits.

10. The sleeve of claim 8 , wherein the sealing frame comprises an adhesive channel peripherally arranged around the sealing frame window opening.

11. The sleeve of claim 8 , wherein the elongate and hollow body comprises a seating region configured to hold the transparent cover, further wherein the sealing frame is configured to secure to the seating region so that an outer surface of the sealing frame is flush with an outer surface of the elongate and hollow body.

12. The sleeve of claim 1 , wherein the elongate and hollow body comprises a seating region configured to hold the transparent cover, further comprising a plurality of snaps projecting into the seating region from a periphery of the window opening, wherein the plurality of snaps are configured to secure the transparent cover within the seating region.

13. The sleeve of claim 1 , wherein the elongate and hollow body comprises a seating region configured to hold the transparent cover, further wherein the window opening comprises a plurality of heat-press detents projecting into the window opening from a periphery of the window opening, wherein the heat-press detents are configured to secure the transparent cover within the seating region.

14. The sleeve of claim 1 , wherein the elongate and hollow body comprises a clamshell body having a living hinge at the distal end of the elongate and hollow body, further wherein a lateral seam on either side of the elongate and hollow body is sealed closed.

15. The sleeve of claim 1 , wherein the sleeve comprises a flavorant to give the sleeve a flavor.

16. The sleeve of claim 1 , wherein the ramp is offset from the window opening by a predetermined distance.

17. The sleeve of claim 1 , wherein the distal facing ramp angle is between ten and fifty degrees.

18. A sleeve for an intraoral scanner, the sleeve comprising:
an elongate and hollow body having a distal end and a proximal end, wherein the distal end is tapered and closed and the proximal end is open to receive an intraoral scanner;
a window opening on a lateral side of the distal end;
a transparent cover over the window opening;
a sealing frame coupled to an outside of the elongate and hollow body so that the transparent cover is sandwiched between a periphery of the window opening and a sealing frame window opening;
an adhesive channel peripherally at least partially around the sealing frame window opening holding an adhesive securing the transparent cover within the window opening; and
a ramp formed integrally within the elongate and hollow body, the ramp including a plurality of ribs extending in a proximal to distal direction and having a distal facing ramp angle and a proximal facing ramp angle greater than the distal facing ramp angle, wherein the ramp is configured to guide a distal end of the intraoral scanner away from the window opening as the intraoral scanner is inserted into the sleeve.

19. The sleeve of claim 18 , wherein the sealing frame is coupled to the elongate and hollow body by one or more snap fits.

20. The sleeve of claim 18 , wherein the elongate and hollow body comprises a seating region configured to hold the transparent cover, further wherein the sealing frame is configured to secure to the seating region so that an outer surface of the sealing frame is flush with an outer surface of the elongate and hollow body.

21. The sleeve of claim 18 , further comprising one or more projections configured to impinge into a field of view of the intraoral scanner from a periphery of the window into the window opening when the intraoral scanner is engaged with the sleeve.

22. The sleeve of claim 18 , further comprising a sleeve extension extending from the proximal end of the elongate and hollow body.

23. The sleeve of claim 22 , wherein the sleeve extension is configured to invert over itself when pulled distally.

24. The sleeve of claim 18 wherein the sleeve is formed of a polyethylene material.

25. A sleeve for an intraoral scanner, the sleeve comprising:
an elongate and hollow body having a distal end and a proximal end, wherein the distal end is tapered and closed and the proximal end is open to receive an intraoral scanner;
a window opening on a lateral side of the distal end;
a transparent cover over the window opening; and
a ramp formed integrally within the elongate and hollow body, the ramp including a plurality of ribs extending in a proximal to distal direction and having a distal facing ramp angle and a proximal facing ramp angle greater than the distal facing ramp angle, wherein the ramp is configured to guide a distal end of the intraoral scanner away from the window opening as the intraoral scanner is inserted into the sleeve, and
wherein the elongate and hollow body comprises a clamshell body having a living hinge at the distal end of the elongate and hollow body, further wherein a lateral seam on either side of the elongate and hollow body is sealed closed.

26. The sleeve of claim 25 , further comprising a foam at least partially circumferentially around the window opening within the hollow body, wherein the transparent cover is secured against the foam.

27. The sleeve of claim 25 , further comprising one or more projections configured to impinge into a field of view of the intraoral scanner from
