Methods of determining an orthodontic treatment comprising: obtaining 3D model of simulated position of teeth following proposed orthodontic treatment; the 3D model comprising a point cloud representation having vector points representative of teeth surface; generating an axis aligned boundary box around each tooth; identifying a pair of tooth-tooth bounding boxes of adjacent teeth that intersect; defining an area of overlap of the pair of tooth-tooth bounding boxes; mapping the area of overlap onto the plurality of vector points, the plurality of vector points populating a 3D grid, having cells, of a simulation space; identifying a subset of the cells including the mapped overlap area, and for only the subset of the cells determining a distance between the vector points relating to adjacent teeth; and determining the proposed orthodontic treatment as the determined orthodontic treatment if the determined distance is more than a predetermined distance.
