GENERATION OF TRANSFORMATION MATRICES ASSOCIATED WITH UPPER AND LOWER DENTAL ARCHES

The invention discloses a solution for generating transformation matrices associated with upper and lower: dental arches. A digital impression of the upper and lower dental arches, or a first digital impression of the upper dental arch and a second digital impression of the lower dental arch is obtained, and a digital three-dimensional model comprising the upper and lower dental arches, or a first digital three-dimensional model comprising the upper dental arch and a second digital three-dimensional model comprising the lower dental arch is/are generated based on the digital impression(s). The digital three-dimensional model(s) is/are output to produce separate physical three-dimensional models of the upper and lower dental arches. Scanning data associated with a desired target occlusion is obtained, the desired target occlusion being obtained based on a desired mutual position of the physical three-dimensional models of the upper and lower dental arches. The transformation matrices of the upper and lower dental arches to the desired target occlusion are determined based on the scanning data and the digital impression(s).
