Abstract
A method of building up a dental object includes steps of (i) determining the three-dimensional shape of the object; (ii) mixing at least a first and a second component to form a hardenable composition; (iii) depositing the hardenable composition through a nozzle; (iv) performing steps (ii) and (iii) in combination with moving the nozzle by computer control based on said data. The invention helps providing an object like a dental restoration at maximized geometric and optical quality.
