Abstract

A model for a dental object, such as a crown, is defined by an upper side and boundary surfaces, determined by scanning, of the jaw where the object is to be placed and between adjacent teeth and/or molars. Provided on the jaw is a filling material, which is machinable at least on the upper side, such that by performing some chewing movements on the filling material an impression of a dynamic chewing surface is formed. The dynamic chewing surface is scanned and recorded in a computer, as well as the scanned boundary surfaces, the computer model being determined on the basis of these data. The dynamic chewing surface can be scanned by means of an optical scanner fixed with respect to a fixed point on the jaw, after which the formed filling material is removed. With the scanner, the form of the part of the jaw and adjacent teeth and/or molars that is complementary to the formed filling material is then scanned.
