Abstract

The present invention relates to a method of producing a dental restoration from a partially-sintered or non-sintered blank using a three-dimensional dental restoration model, comprising the steps of: generating at least one or more first milling path for rough and/or fine milling; determining areas or zones of increased stress in the three-dimensional dental restoration model and generating at least one modified milling path; machining the blank by milling utilizing one or more first milling paths; selectively machining parts of the blank utilizing at least one modified milling path; and sintering the machined blank.
