System and method of forming a custom bleaching tray with trench and material reservoirs

A method for forming a custom bleaching tray, comprising:

• providing or accessing teeth scan data associated with a patent’s mouth;
• generating a digital model of the patient’s mouth based on the teeth scan data, including manipulating the teeth scan data to form:
• a trench between one or more teeth and a gingiva region of the teeth scan data, and
• a bleaching material reservoir on a surface of each of the one or more teeth of the teeth scan data;
• and
• three-dimensionally (3D) printing, based on the digital model, a 3D-printed bleaching tray that includes the trench and the bleaching material reservoir(s).

A system for forming a 3D-printed custom bleaching tray, comprising:

• a computing device configured to access teeth scan data associated with a patent’s mouth;
• a software module, stored in the computing device, including executable instructions configured to generate a digital model of the patient’s mouth based on the teeth scan data, including executable instructions adapted to manipulate the teeth scan data to form:
• a trench between one or more teeth and a gingiva region of the teeth scan data, and
• a bleaching material reservoir on a surface of each of the one or more teeth of the teeth scan data;
• and
• a three-dimensional (3D) printer in communication with the computing device, the 3D printer configured to build, based on the digital model, a 3D-printed custom bleaching tray that includes the trench and the bleaching material reservoir(s).
