Abstract
A dental cast tray subassembly for forming a dental cast model and for mounting to a dental articulator. The tray subassembly forms a channel shaped in a configuration of a human jaw to receive a mold material for forming a dental cast model. The channel further includes ribs for registering the model relative to the channel and a release mechanism for releasing the model from the channel. Further included is a platform for interconnecting with connectors for connecting the subassembly to an articulator.

A dental cast tray subassembly for forming a dental cast model and for mounting to a dental articulator, the subassembly comprising:
- a tray with an outer jaw-shaped periphery with a pair of sidewalls integral with a bottom wall to form a convex canal for receiving a quantity of mold material for forming a dental cast model;
- release means engaged within the tray and about said bottom wall to interface with and adhere to said mold material to release a cured dental cast model from the tray, the release means comprising an elongated continuous slot along said bottom wall with a series of laterally projecting contiguous openings aligned along the length of said continuous slot and an elongated continuous spinal column of a length coinciding with the length of said slot and further comprising a string of interconnected keys with each key projecting laterally and configured of a shape to fit within and interface with one of said contiguous openings;
- and
- registration means within at least one of said sidewalls and about an interior periphery of said canal to interface with said mold material and to register a position of a cured dental cast model.
A dental cast tray subassembly for forming a dental cast model and for mounting to a dental articulator, the subassembly comprising:
- a tray with an outer jaw-shaped periphery with a pair of sidewalls integral with a bottom wall to form a convex canal for receiving a quantity of mold material for forming a dental cast model;
- release means engaged within the tray and about said bottom wall to interface with and adhere to said mold material to release a cured dental cast model from the tray, the release means comprising an elongated spring member including a pair of pliant legs formed as one with the tray and positioned within said canal and separated by a spacing, a spline with a first projection for inserting within said spacing and a second projection for projecting above said spacing to interface with said mold material;
- and
- registration means within at least one of said sidewalls and about an interior periphery of said canal to interface with said mold material and to register a position of a cured dental cast model.
