Abstract
A tool for forming a hump along a substantially flat surface of a dental matrix, Said tool having first and second forming surfaces for urged together to form said hump on said matrix inserted therebetween, said forming surface having one portion part-spherical and another transverse convex arch-shaped project and a flat forming surface extending around of said project, and said second forming surface having one portion part-circular and another transverse concave arch-shaped cavity opposite said project.
Claims20
A forming tool for crimping a substantially flat surface of a dental matrix comprising:
- a first jaw member having a first forming element rising from a flat surface and pivotally connected to a second jaw member having a second forming element;
- said first forming element being a bulbous protrusion;
- said second forming element being an arched-shaped cavity;
- said first forming element and said second forming element being movable towards and away from one another between an open position in which said first forming element and said second forming element are spaced from one another and a closed position in which said first forming element and said second forming element contact each other;
- said second forming element further having a planar surface extending from said arched-shaped cavity forming element with a transverse depression which extends in a predetermined direction within said planar surface and is bounded on three sides by said planar surface defining an open cavity profile that extends away from said pivotal connection and extends out a fourth side through a front face of said second jaw member in said arched-shape, and
- said first forming element bulbous protrusion faces said arched-shaped cavity and essentially makes contact with said first forming element in said closed position.
A tool for forming a hump along a substantially flat surface of a dental matrix comprising:
- said tool having a first and a second forming surface configured for being urged together to form a hump on a dental matrix inserted there between said first and said second forming surfaces;
- said first forming surface having a flat forming surface with a part-spherical projection and a convex transverse arched-shaped projection that extends to a front edge of said first forming surface , and
- said second forming surface having a part-circular shaped and a transverse concave arch-shaped cavity that extends to a front edge of said second forming surface.
