The invention relates to a method for determining a mapping of the contacts and/or distances between the teeth of the maxillary arch and the mandibular arch of a patient, characterised in that it comprises the following steps:obtaining the mandibular kinematics recorded on the patient；obtaining surface meshes of the maxillary arch and the mandibular arch and registering said meshes relative to one another；creating a reduced mesh of at least one of said arches, comprising the selection, in the mesh of said arch, of the cells in which the nodes are located at a distance of less than 1 cm from the mesh of the opposite arch；creating, for each cell of said reduced mesh, a bounding box comprising a plurality of voxels surrounding said cell；using the mandibular kinematics, calculating a network of contacts comprising, for each voxel of the bounding box, information on the existence of a contact between said voxel and a node of the mesh of the opposite arch during a relative movement of the mandibular arch in relation to the maxillary arch.
