Apparatus for positioning a dental dowel

Claim 2

A bridging member for suspending a dental dowel pin upright in a tooth impression cavity of a dental impression, comprising; a main body member adapted to slidably receive upright pin means for support thereby in spaced relation above a tooth impression cavity; said main body member having a secondary body member joined thereto and provided with a slot-like socket to receive and suspend a dowel into said tooth impression cavity; whereby said slot-like socket permits suspension of a dowel at various angular dispositions relative a vertical axis.

Claim 3

A bridging member for positioning a dental dowel pin upright in a tooth impression cavity of a dental impression, comprising; a beam formed of resilient plastic material and being divided into a main body member and a longitudinally contiguous secondary body member; said main body member being adapted to slidably receive upright pin means for support in spaced relation above the cavity of a dental tooth impresssion; said secondary body member being joined in longitudinal contiguity to said main body member by a manually twistable, bendable and frangible web; said web being relatively non-resilient; said secondary body member having an elongated socket to receive and suspend a dowel into the cavity of such dental tooth impression at various angular dispositions relative a vertical axis; and whereby twisting and bending of said web also permits the suspension of such dowel at various other angular dispositions relative said vertical axis.

Claim 4

A bridging member for positioning a dental dowel pin upright in a tooth impression cavity of a dental impression, comprising; a beam formed of resilient plastic material and being divided into a main body member and a longitudinally contiguous secondary body member; said main body member being adapted to slidably receive upright pin means for support in spaced relation above the cavity of a dental tooth impresssion; said secondary body member being joined in longitudinal contiguity to said main body member by a manually twistable, bendable and frangible web; said web being relatively non-resilient; said secondary body member having an elongated socket to receive and suspend a dowel into the cavity of such dental tooth impression at various angular dispositions relative a vertical axis; and whereby twisting and bending of said web also permits the suspension of such dowel at various other angular dispositions relative said vertical axis.

Claim 7

The structure of claim 3 in which the dowel-suspending member has an upwardly-closed and downwardly-open socket to receive and cap a dowel upper end.

Claim 8

The structure of claim 4 in which said socket is slot-like which permits the suspension of such received dowel at various other angular dispositions relative a vertical axis.

Claim 9

The structure of claim 1 in which the joinder of the main and secondary bodies to each other includes means permitting the secondary body to be disposed at various angles relative said main body.
