Systems and methods for generating 3D-representation of tooth-specific platform for dental appliance

A method of generating a 3D-platform representation of a tooth-specific platform for attachment of a dental appliance to a tooth of a patient, the method executable by a processor, the method comprising:

• acquiring, by the processor, a 3D-tooth representation of the tooth,
• the 3D-tooth representation having a surface and having been generated based on the tooth of the patient;
• defining, by the processor, an attachment zone on the surface of the 3D-tooth representation,
• the attachment zone having a zone perimeter enclosing a surface portion of the 3D-tooth representation corresponding to a surface portion of the tooth to which the tooth-specific platform is to be attached;
• generating, by the processor, the 3D-platform representation having (i) a tooth-oriented surface, (ii) a perimeter wall, and (iii) a tooth-opposite surface,
• the generating comprising:
• generating, by the processor, a preliminary 3D-platform representation;
• and
• generating, by the processor, the 3D-platform representation from the preliminary 3D-platform representation by:
• expanding, by the processor, the 3D-tooth representation by a pre-determined distance, thereby generating an expanded 3D-tooth representation having an expanded surface;
• using, by the processor, the expanded surface for cutting the preliminary 3D-platform representation along the preliminary perimeter wall, thereby defining (i) the perimeter wall and (ii) the tooth-opposite surface of the 3D-platform representation;
• the tooth-oriented surface matching the surface portion of the 3D-tooth representation and having a perimeter matching the zone perimeter,
• the perimeter wall extending (i) between the tooth-oriented surface and the tooth-opposite surface and (ii) away from the surface portion, and
• the tooth-opposite surface matching the expanded surface portion of the expanded 3D-tooth representation.
