Automated treatment staging for teeth

A system for staging movement of a plurality of dental objects, comprising:

• one or more processors;
• and
• memory comprising program code that when executed by the one or more processors, cause the one or more processors to:
• receive an electronic representation of each dental object of the plurality of dental objects, the electronic representation being based on a scan from a scanning device and comprising a respective initial position and a respective corrected position for each dental object;
• measure a movement distance between the electronic representation of the respective initial position and the respective corrected position of at least one dental object of the plurality of dental objects;
• use the measured movement distance as a basis for selecting a movement pattern from a plurality of movement patterns for moving the plurality of dental objects towards their corrected positions;
• and
• modify the selected movement pattern by attempting staggering of the at least one dental object of the plurality of dental objects so as to avoid collision or obstruction of the plurality of dental objects on their respective routes to their respective corrected positions;
• and
• if the staggering is unsuccessful in avoiding the collision or obstruction, attempting round-tripping of the at least one dental object.

A system for staging movement of a plurality of dental objects, the system comprising:

• one or more processors;
• and
• memory comprising program code including program code for staggering at least one dental object, program code for round-tripping at least one dental object, and a program code for slowing at least one dental object when executed by the one or more processors, cause the one or more processors to:
• receive an electronic representation of each dental object of the plurality of dental objects, the electronic representation being based on a scan from a scanning device and comprising a respective initial position and a respective corrected position for each dental object;
• measure a movement distance between the electronic representation of the initial position and the corrected position of at least one dental object of the plurality of dental objects;
• use the measured movement distance as a basis for selecting a movement pattern from a plurality of movement patterns for moving the plurality of dental objects towards their corrected positions;
• and
• modify the selected movement pattern by selecting from two or more of staggering, slowing, or round-tripping a dental object of the plurality of dental objects in a predetermined order to avoid collision or obstruction of the plurality of dental objects on their respective routes to their respective corrected positions, and
• wherein in the predetermined order, staggering is attempted prior to slowing, and slowing is attempted prior to round-tripping.

A system for staging movement of a plurality of dental objects, comprising:

• one or more processors:
• and
• memory comprising program code that when executed by the one or more processors cause the one or more processors to:
• receive an electronic representation of each dental object of the plurality of dental objects, the electronic representation being based on a scan from a scanning device and comprising a respective initial position and a respective corrected position for each dental object;
• measure a movement distance between the electronic representation of the respective initial position and the respective corrected position of at least one dental object of the plurality of dental objects:
• use the measured movement distance as a basis for selecting a movement pattern from a plurality of movement patterns for moving the plurality of dental objects towards their corrected positions;
• modify the selected movement pattern by one or more of staggering and round-tripping at least one dental object of the plurality of dental objects so as to avoid collision or obstruction of the plurality of dental objects on their respective routes to their respective corrected positions;
• determine a total distance for each respective dental object to move;
• divide the total distance for each dental object by its respective maximum distance per stage to determine a minimum number of movement stages for each dental object;
• determine a number of non-movement stages for each respective dental object;
• add the minimum number of movement stages to the number of non-movement stages for each dental object to determine a minimum number of stages for each respective dental object;
• and
• select the largest of the minimum number of stages as a total number of movement stages for moving the plurality of dental objects from their respective initial positions to their respective corrected positions.

A non-transitory computer-readable storage medium comprising program code that, when executed by one or more processors, cause the one or more processors to:

• receive an electronic representation of each dental object of the plurality of dental objects, the electronic representation being based on a scan from a scanning device and comprising a respective initial position and a respective corrected position for each dental object;
• measure a movement distance between the electronic representation of the initial
• position and the corrected position of at least one dental object of the plurality of dental objects;
• use the measured movement distance as a basis for selecting a movement pattern from a plurality of movement patterns for moving the plurality of dental objects towards their corrected positions;
• and
• modify the selected movement pattern by round-tripping at least two dental objects of the plurality of dental objects so as to avoid collision or obstruction of the plurality of dental objects on their respective routes to their respective corrected positions.
