Apparatus, system, and methods for utilizing one or more computing devices to stage the movement of teeth during an alignment treatment are disclosed. The computing device receives an electronic representation of the patient's teeth in their initial position and an electronic representation of the teeth a final position for each tooth. A route each tooth will travel to reach its final position is determined, and the teeth are scheduled to move according to a movement pattern. Moreover, the schedule of movement takes into account a maximum rate of tooth movement for each tooth, the path of movement for each tooth, the distance each tooth needs to move, any needed tooth staggering, any needed round-tripping or tooth movement slowing. The invention also includes techniques for determining an optimum number of stages for the treatment based on the schedule of movement.

1. A computer-implemented method for staging movement of a plurality of dental objects, the method comprising: receiving, at a host computer, an electronic representation of each dental object of the plurality of dental objects in relation to one another, the electronic representation comprising each dental object in a respective initial position;receiving, by the host computer, an electronic representation of a corrected position for each respective dental object;measuring, by the host computer, a movement distance between the electronic representation of the initial position and the electronic representation of the corrected position of at least one dental object of the plurality of dental objects;using the measured movement distance as a basis for selecting, by the host computer, a movement pattern from a plurality of movement patterns for moving the plurality of dental objects towards their corrected positions; andmodifying, by the host computer, the computer-selected movement pattern at least by staggering or 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 corrected positions. 2. The computer-implemented method of claim 1, further comprising: determining a total distance each respective dental object will move;dividing 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;determining a number of non-movement stages for each respective dental object;adding 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; andselecting 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. 3. The computer-implemented method of claim 1, wherein modifying the computer-selected movement pattern comprises staggering the movement of at least two dental objects. 4. The computer-implemented method of claim 1, wherein modifying the computer-selected movement pattern comprises round-tripping at least two dental objects. 5. The computer-implemented method of claim 1, wherein modifying the computer-selected movement pattern comprises slowing the movement of at least one dental object. 6. The computer-implemented method of claim 1, wherein the modifying comprises: attempting staggering of the at least one dental object; andif the staggering is unsuccessful in avoiding the collision or obstruction, attempting round-tripping of the at least one dental object. 7. A computer-implemented method for staging movement of a plurality of dental objects, the method comprising: receiving, at a host computer, an electronic representation of each dental object of the plurality of dental objects in relation to one another, the electronic representation comprising each dental object in a respective initial position;receiving, by the host computer, an electronic representation of a corrected position for each respective dental object;measuring, by the host computer, a movement distance between the electronic representation of the initial position and the electronic representation of the corrected position of at least one dental object of the plurality of dental objects;using the measured movement distance as a basis for selecting, by the host computer, a movement pattern from a plurality of movement patterns for moving the plurality of dental objects towards their corrected positions based at least in part on a distance between the initial position and the corrected position of at least one dental object of the plurality of dental objects; andmodifying, by the host computer, the computer-selected movement pattern at least by attempting to apply a plurality of collision-avoidance techniques comprising at least two of staggering, slowing, and round-tripping in a predetermined order to avoid collision or obstruction of the plurality of dental objects on their respective routes to their corrected positions. 8. The computer-implemented method of claim 7, wherein modifying the computer-selected movement pattern comprises at least one of staggering or round-tripping at least one of the plurality of dental objects. 9. The computer-implemented method of claim 7, wherein the plurality of movement patterns comprise at least two of the group consisting of an all-equal pattern, a V-shaped pattern, an A-shaped pattern, an M-shaped pattern, and a mid-line shift pattern. 10. The computer-implemented method of claim 7, further comprising: determining a total distance each respective dental object will move;dividing 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;determining a number of non-movement stages for each respective dental object;adding 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; andselecting the largest of the minimum number of stages as the total number of movement stages for moving the plurality of dental objects from their respective initial positions to their respective corrected positions. 11. The computer-implemented method of claim 7, wherein modifying the computer-selected movement pattern comprises staggering the movement of at least two of the plurality of dental objects. 12. The computer-implemented method of claim 7, wherein modifying the computer-selected movement pattern comprises round-tripping at least two of the plurality of dental objects. 13. The computer-implemented method of claim 7, wherein modifying the computer-selected movement pattern comprises slowing the movement of at least one of the plurality of dental objects. 14. The computer-implemented method of claim 7, wherein the predetermined order comprises staggering, followed by slowing, then followed by round-tripping.
