摘要

A computer implemented method for fixing the mounting locations (p) of a plurality of preformed attachment elements (22) for a substantially flat or substantially the course of the spee''s curve following wire spring (28) of a dental apparatus to associated teeth (12) of at least one jaw (36, 38) of a patient, comprising the steps of:1a) creating a three-dimensional digital data model of the actual position of the teeth (12) of the patient,1b) transforming the three-dimensional digital data model of the actual position of the teeth (12) in a three-dimensional digital data model of a desired position of the teeth (12),1c) for each tooth (12) of: determining a starting position of a corresponding pad (22) as the instantaneous position of this pad (22),1d) for each tooth (12): performing a collision check for the respective momentary positions (p) of the engagement elements (22),1e) changing the position (p) of at least one pad (22), if the collision check for at least one catch element (22) is a collision with a tooth (12) or / and another catch element (22) or / and the wire spring (28) has,1f) repeating steps (1d and 1e), to the collision check for none of the engagement elements (22) is a collision or a predetermined termination criterion has been reached.The present invention also relates to a display with a linear side-by-side arrangement of the teeth (12) for facilitating easy comprehension of the collision situation of the teeth (12).
