Abstract
In methods for constructing orthodontic appliances constructed from multiple layers or shells, solvents can be utilized to bond the multiple layers or shells together. Such a construction technique overcomes the aforementioned issues with utilizing preformed laminates and also allows for addition of agents between the layers when the appliance is constructed.
Claims18
A method for forming an orthodontic appliance, the method comprising:
- thermoforming a first layer to have a first concave surface shaped to fit onto teeth;
- thermoforming a second layer to have a second concave surface shaped to fit onto the first layer;
- and
- bonding the first layer to the second layer using a solvent to form a multilayer orthodontic appliance;
- wherein the solvent includes one or more of a miscible or soluble therapeutic and/or one or more of a miscible or soluble wear-enhancing agent.

- thermoforming a first layer to have a first concave surface shaped to fit onto teeth;
- thermoforming a second layer to have a second concave surface shaped to fit onto the first layer;
- thermoforming a third layer to have a third concave surface shaped to fit onto the second layer and a convex outer surface to be exposed to an oral cavity;
- and
- bonding the second layer to the third layer using a solvent to form a multilayer orthodontic appliance,
- wherein the solvent includes one or more of a miscible or soluble therapeutic and/or one or more of a miscible or soluble wear-enhancing agent.
