## Abstract

The invention provides a disposable dental mirror tool combined with a disposable suction means, enabling simultaneously viewing the patient's mouth and cleaning liquids and debris formed during dental procedures.

## Claims

### Claim 1

A disposable dental suction mirror tool, comprising:
i) a mirror frame (1) made of a single plastic piece shaped to comprise:
a) a circular section (11) for accommodating a circular mirror, defining a mirror plane;
b) an oblong opening (7) adjacent to said circular section for evacuating fluids from said mirror, defining a front part of said frame;
c) a cylindrical suction tube base (3) for inserting into a standard dental suction tube, the tube serving as a handle and connecting said dental tool with a vacuum source, said cylinder and said mirror plane forming an angle of between 50° and 60° ; and
d) a circular, back opening (8) for evacuating fluids from behind and beneath said frame, defining a backside part of said frame;
ii) a frame bottom (10) having a circular edge and located in said circular section for supporting said mirror; and
iii) a planar anti-fog mirror (2) to be attached on said frame bottom in said circular section; said angle and said openings allowing for optimal liquid flow relative to the mirror plane and for effectively removing fluids and debris created during a dental procedure, thereby preventing the mirror from becoming non-reflective; and
wherein said mirror has a smaller diameter than said frame circular section into which said mirror is set, allowing sucked liquid to move also between the mirror edge and the frame to below the mirror surface, said frame bottom further being provided with a circular ridge, concentric with said circular edge of the bottom and elevated toward the mirror; said mirror sits on the ridge, creating a free space between said mirror and said bottom, wherein a part of the sucked liquid moves from above the mirror surface via said space and via said front oblong opening to the suction tube.

### Claim 2 (depends on 1)

The dental tool of claim 1, wherein said frame and said frame bottom constitute an integrated disposable plastic unit.

### Claim 3 (depends on 1)

The dental tool of claim 1, wherein said frame bottom is attached to said round section by welding, for example by ultrasonic welding.

### Claim 4 (depends on 1)

The dental tool of claim 1, wherein said mirror is provided with an adhesive layer and is attached to said frame bottom by the adhesive layer.

### Claim 5 (depends on 1)

The dental tool of claim 1, wherein said circular section is provided with snaps, and said mirror is held in said frame by said snaps.

### Claim 6 (depends on 1)

The dental tool of claim 1, wherein said front opening efficiently evacuates liquids from the surface of said mirror, and said back opening prevents accumulation of liquids behind and/or below the tool and sudden immersion of the mirror surface.

### Claim 7 (depends on 1)

The tool according to claim 1, wherein the anti-fog mirror comprises a thermoplastic polymer.

### Claim 8 (depends on 7)

The tool according to claim 7, wherein the polymer is glycol-modified polyethylene terephthalate (PETG).

### Claim 9 (depends on 1)

The tool according to claim 1, allowing for simultaneous viewing in the patient's mouth and cleaning debris formed during dental procedures.
