Abstract
In one aspect, the present application provides a method for fabricating shell-shaped dental appliance, comprising: generating a first 3D digital model representing an assembly of a support and a shell-shaped dental appliance, where the support has a first surface that conforms to and clings to a second surface of the shell-shaped dental appliance; and using the first 3D digital model to control a device to discharge successive drops of at least one fluid phase and solidifiable appliance material and successive drops of at least one fluid phase and solidifiable support material to form the assembly slice by slice along a first direction.

A method for fabricating shell-shaped dental appliance, comprising:
- generating a first 3D digital model representing an assembly of a support and a shell-shaped dental appliance, where the support has a first surface that conforms to and clings to a second surface of the shell-shaped dental appliance;
- using the first 3D digital model to control a device to discharge successive drops of at least one fluid phase and solidifiable appliance material for forming the shell-shaped dental appliance, and successive drops of at least one fluid phase and solidifiable support material for forming the support;
- and
- forming the assembly including both the shell-shaped dental appliance and the support together slice by slice along a first direction,
- wherein the shell-shaped dental appliance is a tooth repositioner for repositioning teeth of a patient from a first tooth arrangement to a second tooth arrangement which is different from the first tooth arrangement, and
- wherein the tooth repositioner is a one piece shell which forms a cavity for receiving the teeth, and the first 3D digital model is generated based on a 3D digital model represent the second tooth arrangement.
