Abstract
By combining the wide field of the image sensor of a smartphone () or the like, with the precision of the image sensor of an IOS () or the like, the process of generating a three-dimensional reconstruction of a patient's dental arch, referred to as extended optical impression, is improved and simplified. More specifically, the practitioner can take, in a single image, a global but not very precise 3D reconstruction () of the arch, then substitute, for the areas (or sectors) of this reconstruction which require a finer precision, precise local 3D reconstructions () obtained with the IOS. A related algorithm () is responsible for merging the global reconstruction with each of the local reconstructions, in order to produce a single precise 3D reconstruction () which corresponds to the desired optical impression.
