Abstract: Method for determining a manufacturing parameter for making an aligner with a desired aligner thickness using a thermoforming device operable for making the aligner by shaping a precursor aligner into the aligner using a mold representative of a dental archform, the method comprising: obtaining a 3D map associated with the dental archform; parsing the 3D map to determine a first property value and a second property value, the first property value being based on the 3D map and the second property value being derived from a 2D projection of the 3D map, and determining a thickness of the precursor aligner for obtaining the desired aligner thickness based on a ratio of the first property value and the second property value and a given value of an operating parameter of the thermoforming device; and sending instructions to the thermoforming device to make the desired aligner based on the determined operating parameter.

Abstract: A method and processor for generating a 3D-platform representation of a tooth-specific platform for attachment of a dental appliance to a tooth of a patient are disclosed. The method includes acquiring a 3D-tooth representation of the tooth, and defining an attachment zone on the surface of the 3D-tooth representation. The attachment zone has 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. The method also includes generating the 3D-platform representation having (i) a tooth-oriented surface matching the surface portion of the 3D-tooth representation and having a perimeter matching the zone perimeter, (ii) a perimeter wall extending between the tooth-oriented surface and the tooth-opposite surface and away from the surface portion, and (iii) a tooth-opposite surface matching an expanded surface portion of the 3D-tooth representation.

Abstract: A method for forming a desired bend angle in an orthodontic appliance comprising: monitoring bending of the orthodontic appliance in a gripped state, the monitoring being continuous; in response to an initial bend angle in the orthodontic appliance in the gripped state being reached, causing the release of at least a portion of the orthodontic appliance so that orthodontic appliance is in a free state, measuring resultant angle of the bend in the free state; in response to resultant angle being within a predefined tolerance of the desired bend angle, determining that desired bend angle has been reached.
