Abstract
A method for the production of inserts or the like is shown, with a patient or also a healthy person standing/walking/sitting/lying/biting in a defined position and/or movement with the body part to be fitted (foot, buttocks/back, teeth) on/over an electronic measuring arrangement for two- or three-dimensional measurement of the forces (pressures) acting on the measuring arrangement. The output signals of the measuring arrangement corresponding to the pressure-force distribution under the body part in the two- or three-dimensional pattern of the pressure-force distribution are relayed to a computer and compared with a stored set of desired values (wanted or ideal data). The differences between the distribution patterns are transformed into control signals for controlling an apparatus for the manufacture of the inserts or seating furniture surfaces, lounging furniture surfaces, dental prostheses, in such a way that upon addition of the (virtual) pressure force compensation distribution in accordance with the form (height) and/or rigidity of the inserts or the like to be manufactured to the actual pressure force distribution pattern, the desired pressure force distribution pattern es…
