Abstract

Embodiments may provide improved techniques for creating custom lingual or labial ceramic orthodontic brackets, and which provides the capability for in-office fabrication of such brackets. For example, a method of manufacturing customized ceramic labial/lingual orthodontic brackets by ceramic slurry-based AM may comprise measuring dentition data of a profile of teeth of a patient, based on the dentition data, creating a three dimensional computer-assisted design (3D CAD) model of the patient's teeth using reverse engineering, and saving the 3D CAD model on a computer, designing a 3D CAD bracket structure model for a single labial or lingual bracket structure, importing data related to the 3D CAD bracket structure model into a ceramic slurry-based AM machine, directly producing the bracket (green part) in the ceramic slurry-based AM machine by layer manufacturing, and processing the brackets in a sintering and debinding oven prior to direct use.
