Abstract
A dental suction mirror with a plurality of suction ports on the periphery of the reflective surface spaced apart substantially about a forward half of the mirror with the ports directed across the reflective surface. The mirror also includes a plurality of lower suction holes directed out of the cavity downward from a bottom of the mirror. The reflective surface of the mirror is replaceable.

A dental mirror with mirror cleaning suction, comprising a mirror having a reflective surface and with a plurality of suction ports on the periphery of the reflective surface with the suction ports directed across the reflective surface,
- a handle extending from the mirror and providing fluid communication through the handle between a suction device connectable to a handle first end and the mirror at a handle second end, the suction ports in fluid communication with the handle second end such that suction applied to the suction handle first end draws air across the mirror reflective surface and out the suction handle first end, wherein the mirror includes a cavity in fluid communication with the handle second end, the suction ports opening into the cavity,
- wherein, a forward rim is on the forward half of the mirror and a rearward rim is on the rearward half of the mirror, and
- wherein the reflective surface comprises a removable plate that covers a top of the cavity, the plate secured under the rims when installed on the mirror, and
- wherein two of which suction ports function as a pair of access ports, which access ports are diametrically opposed with centers on a diameter dividing the mirror forward and rearward halves through which access ports a forward portion of the plate is slidable into the cavity and under the forward rim during installation of the plate,
- a rearward support rearward in the cavity,
- a support fulcrum in the cavity,
- a resilient forward support forward in the cavity depressed by the forward portion of the plate as it slides into the cavity during installation, wherein as a rearward portion of the plate clears the rearward rim, the forward support urges the forward portion of the plate upward against the forward rim with the rearward portion of the plate urged downward against the rearward support as the plate rotates on the fulcrum, such that after the plate is urged rearward on the rearward support under the rearward rim the plate is supported by the rearward and forward supports under the rearward and forward rims.
A dental mirror with mirror cleaning suction, comprising
- a mirror with a reflective surface with a plurality of suction ports on the periphery of the reflective surface with the suction ports directed across the reflective surface,
- a handle extending from the mirror and providing fluid communication through the handle between a suction device connectable to a handle first end and the mirror at a handle second end, the suction ports in fluid communication with the handle second end such that suction applied to the suction handle first end draws air across the mirror reflective surface and out the suction handle first end,
- wherein the suction ports are spaced apart substantially about a forward half of the mirror with the handle extending from central in a rearward half of the mirror, two of which suction ports function as a pair of access ports, which access ports are diametrically opposed with centers on a diameter dividing the mirror forward and rearward halves,
- wherein a forward rim on the forward half of the mirror and a rearward rim on the rearward half of the mirror, and
- wherein the reflective surface comprises a removable plate that covers a top of the cavity, the plate secured under the rims when installed on the mirror, and
- wherein a forward portion of the plate is slidable into the cavity through the access ports and under the forward rim during installation of the plate,
- a rearward support rearward in the cavity,
- a support fulcrum in the cavity,
- a resilient forward support forward in the cavity depressed by the forward portion of the plate as it slides into the cavity during installation, wherein as a rearward portion of the plate clears the rearward rim, the forward support urges the forward portion of the plate upward against the forward rim with the rearward portion of the plate urged downward against the rearward support as the plate rotates on the fulcrum, such that after the plate is urged rearward on the rearward support under the rearward rim the plate is supported by the rearward and forward supports under the forward and rearward rims.
A dental mirror with mirror cleaning suction, comprising
- a mirror with a reflective surface with a plurality of suction ports on the periphery of the reflective surface spaced apart substantially about a forward half of the mirror with the suction ports directed across the reflective surface,
- two of which suction ports function as a pair of access ports, which access ports are diametrically opposed with centers on a diameter dividing the mirror forward and rearward halves,
- the mirror including a cavity in fluid communication with a handle second end, the suction ports opening into the cavity, the mirror further including a plurality of lower suction holes directed out of the cavity downward from a bottom of the mirror,
- a handle extending from central in a rearward half of the mirror and providing fluid communication through the handle between a suction device connectable to a handle first end and the cavity at a handle second end, such that suction applied to the suction handle first end draws air across the mirror and out the suction handle first end,
- and further comprising a forward rim on the forward half of the mirror and a rearward rim on the rearward half of the mirror, and
- wherein the reflective surface comprises a removable plate that covers a top of the cavity, a forward portion of the plate being slidable into the cavity and under the forward rim through the access ports during installation of the plate, the plate being secured under the rims,
- a rearward support rearward in the cavity,
- a support fulcrum in the cavity,
- a resilient forward support forward in the cavity depressed by the forward portion of the plate as it slides into the cavity during installation, wherein as a rearward portion of the plate clears the rearward rim, the forward support urges the forward portion of the plate upward against the forward rim with the rearward portion of the plate urged downward against the rearward support as the plate rotates on the fulcrum, such that after the plate urged rearward on the rearward support under the rearward rim the plate is supported by the rearward and forward supports under the forward and rearward rims,
- wherein the forward rim is of inner radius smaller than the rearward rim, and
- wherein the forward rim is separated from the rearward rim by said access ports.
