Systems for fabrication of dental appliances with elongate shafts and connectors

A system comprising:

• an additive manufacturing system configured to perform an additive manufacturing process;
• one or more processors;
• and
• a memory operably coupled to the one or more processors and storing instructions that, when executed by the one or more processors, cause the additive manufacturing system to perform operations comprising:
• fabricating a first elongate shaft having a first connection region for connecting to a shell of a dental appliance,
• fabricating a second elongate shaft having a second connection region for connecting to the shell or to a tooth,
• fabricating a first elongate connector coupled to the first and second elongate shafts, and
• fabricating a second elongate connector coupled to the first elongate shaft and extending toward the second elongate shaft,
• wherein the first and second elongate connectors are coupled to the first elongate shaft at respective locations separate from the first connection region, and
• wherein the first elongate connector is coupled to the second elongate shaft at a location separate from the second connection region.
