Abstract
The present technology comprises methods of manufacturing an orthodontic appliance. For example, a method can include forming an orthodontic appliance in an intermediate configuration by a casting process. The method can further include securing the appliance to a shape forming fixture such that the appliance assumes a desired configuration. The shape forming fixture can comprise a gingiva portion including a surface having a shape corresponding at least in part to a gingiva of a patient and a securing portion carried by the gingiva portion and configured to releasably secure to a portion of the appliance. The method can further include setting a shape of the appliance while the appliance is secured to the shape forming fixture.
Claims (16)
1 . A method of manufacturing an orthodontic appliance, the method comprising:
obtaining a digital model of an appliance in an intermediate configuration;
forming the appliance in the intermediate configuration by successively fusing particles of a material;
securing the appliance to a shape forming fixture such that the appliance assumes a desired configuration, the shape forming fixture comprising a gingiva portion comprising a surface having a shape corresponding at least in part to a gingiva of a patient and a securing portion carried by the gingiva portion and configured to releasably secure to a portion of the appliance; and
setting a shape of the appliance while the appliance is secured to the shape forming fixture.
2 . The method of claim 1 , wherein the appliance is substantially flat in the intermediate configuration, and wherein the appliance is contoured in the desired configuration.
3 . The method of claim 1 , wherein forming the appliance comprises successively fusing the particles of the material without forming support structures.
4 . The method of claim 1 , wherein the material comprises a metal and/or a metal alloy.
5 . The method of claim 1 , wherein the material comprises a powder or a filament.
6 . The method of claim 1 , wherein successively fusing the particles of the material comprises delivering at least one of thermal energy, a binding agent, or a compressive force to the particles.
7 . The method of claim 1 , wherein the intermediate configuration is a two-dimensional (2D) representation of the appliance.
8 . The method of claim 1 , further comprising cold working the appliance in the intermediate configuration to modify a material property of the appliance.
9 . The method of claim 8 , wherein cold working the appliance comprises compressing the appliance.
10 . The method of claim 8 , wherein cold working the appliance comprises rolling the appliance.
11 . The method of claim 8 , wherein cold working the appliance to modify the material property of the appliance comprises increasing at least one of a stiffness, a hardness, or a strength of the appliance.
12 . The method of claim 8 , wherein cold working the appliance to modify the material property of the appliance comprises reducing a surface roughness of the appliance.
