Additively manufactured orthodontic appliances

At least one non-transitory computer-readable medium comprising instructions that, when executed by one or more hardware processors of at least one computing device, cause the one or more hardware processors to at least:

• access data related to a three dimensional (3D) computer aided design bracket structure model for a custom metal orthodontic bracket in a light-polymerizable material-based additive manufacturing (AM) machine;
• and
• cause direct production of the customized metal orthodontic bracket in the AM machine by layer manufacturing, the custom metal orthodontic bracket comprising:
• a body;
• a face;
• a plurality of tie-wings at the face;
• and
• a base comprising:
• a base surface that is contoured to a shape of a tooth of a patient to which the custom metal orthodontic bracket is to be bonded;
• and
• a plurality of retentive structures,
• wherein a slope of the face and a slope of the base are designed to provide a custom torque for the tooth of the patient.

A method comprising:

• accessing a three-dimensional (3D) model of at least one tooth of a patient;
• designing, by using the 3D model of the at least one tooth of the patient, a 3D model of a custom metal orthodontic bracket, the 3D model of the bracket comprising:
• a body;
• a face;
• a plurality of tie-wings at the face;
• and
• a base comprising:
• a base surface that is contoured to a shape of a tooth of a patient to which the custom metal orthodontic bracket is to be bonded;
• and
• a plurality of retentive structures,
• wherein a slope of the face and a slope of the base are designed to provide a custom torque for the tooth of the patient;
• and
• building the bracket by using an additive manufacturing device and the 3D model of the bracket.
