1. Method for evaluating a dental situation of a patient, said method having the following successive steps:
1) Generating an initial model of at least one dental arch of the patient;
2) Splitting the initial model in order to define a tooth model for each of at least some of the teeth represented on the initial model and thereby to obtain a split model;
3) Defining an initial support curve in the split model;
4) Fixing each tooth model virtually to the initial support curve;
5) Modifying the split model by deformation of the initial support curve, thereby modifying a position and/or an orientation of the tooth models without modifying the tooth models, until a deformed support curve is obtained, so as to obtain a first deformed model,
wherein each model being a three-dimensional digital representation.
