Abstract

A dental wedge and forming device utilizing a unitary body having a pair of wings which are intended to lie against the outer surfaces of adjacent teeth, either on the lingual or buccal region of the teeth. A curved nose is constructed to extend between the adjacent teeth and includes a flat side and an opposite radiused side. A pair of the devices are nested in opposition in order to hold a dental matrix band in place about a prepared tooth, thus allowing a dental practitioner to practice proper biomimetic restorative techniques.

Claims (14)

1. A dental wedge device configured to be positioned between a first tooth and an adjacent second tooth, at least one of the first and second teeth having a matrix band, comprising:

a. a curved elongated member extending along a dimension of elongation, said curved elongated member including at least a first concave surface and an opposite flattened surface, transverse to said dimension of elongation;

b. a first wing having a certain height, said first wing having a direct connection to said curved elongated member; and

c. a second wing having a certain height, said second wing having a direct connection to said curved elongated member at said connection of said first wing to said curved elongated member, said curved elongated member sloping outwardly from said connections of said first and second wings and terminating in a tip of lesser height than said certain heights of said first and second wings.

2. The device of claim 1 in which said first and second wings each possess a curved surface.

3. The device of claim 2 which additionally comprises a recess in the vicinity of said direct connections of said first and second wings to said curved elongated member.

4. The device of claim 2 which additionally comprises an appendage extending from said curved elongated member, apart from said tip.

5. The device of claim 1 which additionally comprises a recess in the vicinity of said direct connections of said first and second wings to said curved elongated member.

6. The dental wedge device of claim 5 in which said dental wedge device comprises a first dental wedge device and which further comprises, in combination, a second dental wedge device, said second dental wedge comprising:

a. a curved elongated member extending along a dimension of elongation, said curved elongated member including at least a first concave surface and an opposite flattened surface, transverse to said dimension of elongation;

b. a first wing having a certain height, said first wing having a direct connection to said curved elongated member; and

c. a second wing having a certain height, said second wing having a direct connection to said curved elongated member at said connection of said first wing to said curved elongated member, said curved elongated member sloping outwardly from said connections of said first and second wings and terminating in a tip of lesser height than said certain heights of said first and second wings, and having a recess in the vicinity of said direct connections of said first and second wings, and, further, in combination; and

d. a dental separator for exerting a force at said recess of said first device and at a recess of said second device.

7. The device of claim 1 which additionally comprises an appendage extending from said curved elongated member, apart from said tip.
