A shaped article, specifically an artificial tooth, is made of two parts. An individually shaped first part 18, specifically the head part or superstructure of the artificial tooth, has a standardized locking portion 26 for engagement with a standardized counter-locking portion 24 provided on a pre-fabricated second part 16, specifically the shaft part of the tooth to be implanted in a patient's jaw. The individually shaped part 18 is manufactured by using a pre-fabricated sonotrode 38 for producing the configuration of the locking portion 26 and one or more individually produced shaping sonotrodes 44 are used for generating the parts of the surface other than the locking portion 26. This permits the individually shaped part to be produced in an economic way yet with high precision of the locking portion.
