1. A method of manufacturing an orthodontic appliance for a subject, the method being executable by a processor, the method comprising:
receiving, by the processor, a 3D mesh including an arch form 3D representation of an arch form mold associated with the subject used for manufacturing the orthodontic appliance, the arch form mold being representative of subject's teeth to which the orthodontic appliance is to be applied, the 3D mesh including a plurality of inner vertices representative of an inner surface of the orthodontic appliance;
generating, by the processor, a cover surface encompassing the plurality of inner vertices of the 3D mesh, such that the cover surface is spaced from at least some of the plurality of inner vertices;
determining, by the processor, based on the 3D mesh, for each one of the plurality of inner vertices, a respective distance therefrom to the cover surface,
the respective distance associated with a given inner vertex being indicative of a thickness of the orthodontic appliance after forming a preform on the arch form mold;
determining, by the processor, based on the respective distance, for each one of the plurality of inner vertices, a respective offset distance for displacement thereof along the respective normal vector, thereby generating a plurality of outer vertices representative of an outer surface of the orthodontic appliance;
generating, by the processor, based on the plurality of inner vertices and the plurality of outer vertices, an orthodontic appliance 3D representation of the orthodontic appliance including data indicative of the thickness of the orthodontic appliance after forming the preform on the arch form mold;
causing the manufacturing of the orthodontic appliance based at least in part on the orthodontic appliance 3D representation.
