Instructional model for teaching horizontal cone shift technique also known as slob (same lingual opposite buccal) technique

Abstract

A horizontal cone shift model includes a baseboard having two mounting openings in parallel orientation to a width of the baseboard. A background board is attached to the baseboard along its length to represent a radiographic film. A plurality of magnetic labels are provided for placement on the baseboard and background board. A first rod and a second rod fit into each of the two mounting openings. The first rod is distinguishable from the second rod. A light source is located on the baseboard and is movable along the length of the baseboard such that shadows of the first rod and second rod appear on the background board. The plurality of labels are used to identify the first and second rods and locations.

Dependencies are inferred from the claim text.
