ABSTRACT:
A system for production of a dental crown (23, 24) includes identification equipment (2), modeling equipment (9), ordering equipment (6), and an automated production arrangement (16). The latter, as a function of one or more first information items, is arranged to effect production, by means of pressing or pressure-casting, of an integrated dental crown which is made up of two layers. The first layer comprises or consists of porcelain material, and the second layer consists of aluminum oxide, zirconium oxide, etc. The second layer forms a cap, via which the dental crown can be applied to a tooth stump (28) of a patient (1). The invention also relates to a dental replacement component consisting of the dental crown. It relates also to an arrangement used for a preliminary stage in production of a dental crown, which arrangement is characterized by a cylinder-shaped unit (puck) which is made of porcelain material and can be pressed against the cap under vacuum and at high pressure in order to form the first layer. The invention permits accelerated and efficient production of individual dental crowns.
