Abstract

An apparatus for separating teeth utilizing a base member having a first end portion, a second end portion, and an intermediate portion. A first spring extends outwardly from the first end portion while a second spring extends outwardly from the second portion of the base member. A lingual shield spans the distal portions of the first and second springs extending from the base member. A pair of tines overlap one another, one tine extending from the base member, the other extending from the shield. The first and second springs urge the meeting or overlapping of the first and second tines in the vicinity of gap for meeting place between a pair of teeth.

Claims (23)

1. An apparatus for separating a pair of adjacent teeth, comprising:

a. a base member, said base member including a first end portion, a second end portion and an intermediate portion interconnecting said first and second end portions;

b. a first spring extending outwardly from said first end portion of said base member, said first spring including a proximal portion connected to base member, and a distal portion;

c. a second spring extending outwardly from said second end portion of base member said second spring including a proximal portion connected to said base member and a distal portion;

d. a lingual shield said lingual shield spanning said distal portions of said first and second springs;

e. a first tine extending from said base member;

f. a second tine extending from said lingual shield toward said first tine, said first and second springs urging the meeting of said first and second tines; and

g. a slit positioned in the lingual shield and aligned with the first and second tines for allowing a cutting or abrading tool to pass through the lingual shield.

2. The apparatus of claim 1 in which said first and second tines each include a tip and said base member includes a bottom edge, said tip of said first tine position at a level above base bottom edge of said base member further than said tip of said second member.

3. The apparatus of claim 1 in which said first and second springs comprise bands.

4. The apparatus of claim 1 in which said first tine includes an orthogonal edge.

5. The apparatus of claim 4 in which said second tine includes an orthogonal edge.

6. The apparatus of claim 1 in which said first tine includes a curved edge.

7. The apparatus of claim 6 in which said second tine includes a curved edge.

8. The apparatus of claim 1 which further comprises a saw, said saw passing through the slit and over said first and second tines.

9. The apparatus of claim 8 , wherein the saw is for interproximal reduction of enamel and for use with a reciprocating element, the saw comprising:

a. a plate, said plate having a first side, a second side, and a perimetric edge between said first and second sides;

b. an abrasive, said abrasive applied to only said first side of said plate; and

c. a shaft, said shaft connected to said plate and the reciprocating element.

10. The saw of claim 9 which further comprises an abrasive-free zone on said first side of said plate and adjacent said perimeter of said plate.

11. The apparatus of claim 1 in which said first tine includes a crease, and further comprises a saw passing over said first and second tines, said crease of said first tine guiding movement of said saw.

12. The apparatus of claim 1 which additionally comprises a protuberance extending from said lingual shield.

13. The apparatus of claim 1 which additionally comprises a protuberance extending from said base member.
