| Abstract: |
Dental appliances formed using this method provide projections of the appliance itself which provide the necessary gripping forces rather than extraneous wires or other parts. The projections are formed by cutting grooves in casts of the teeth arches which will result in a projection, which will bear against the teeth, when the cast surface is duplicated in plastic. A first embodiment forms upper and lower plastic components, each having projections from the casts using the lost wax technique. These components are joined together in a predetermined relationship using a wax bite registration taken while the patient held his jaw in the predetermined relationship, and a dental articulator. A second method forms the plastic components directly over the casts. In this method the components are joined together, while mounted over the patient's arches, with the patient holding his jaw in the predetermined relationship. Both methods can be used to produce a single component with no joining of components then being required.

I claim:
1. A method of manufacturing a dental appliance comprising the steps of:
- a) preparing impression material, loading an impression tray with the prepared impression material, taking an impression of a first dental arch using the impression tray, allowing the impression material to cure, removing the impression tray from the dental arch; and
- b) preparing a stone mixture, filling the impression of the first dental arch in the impression tray with the stone mixture, allowing the mixture to harden, removing the resulting cast from the impression; and
- c) cutting grooves in the teeth replicas in the cast of the first dental arch, the grooves being oriented essentially parallel to the occlusal surfaces and positioned between the gum tissue replica and the height of contour of the tooth replica, having at least one groove on the buccal side of at least two posterior teeth, the teeth being located on opposite sides of the dental arch, and
- d) using said cast of the first dental arch as a form in making a plastic first component for the first dental arch, which will fit and cover the teeth extending to near the gumline; and
- e) smoothing and polishing said first component.
