Live from the robot production!
Excess pressure is maintained in the room to keep dirt particles completely out. The machine operators are met by a sticky doormat when they enter. The VITA-designed production plant for denture teeth is continuously used. Guests are greeted by a variety of background noise, including regular hisses, clicks and vibrations.
Right at the entrance, the composite materials are stored in deep freezers. Maturation is put on hold in the packaged dough. Enamel, dentin, and cervical materials are waiting to be cured in a strong bond to create denture teeth.
The time has come: The dough is removed and precisely rolled out to the required plate thickness. Professionals call this calendering. After cutting, the composite mass is placed on special plates, which will later be used by the robot arms. These prepared material plates are stored on call in a refrigerator until the production line accesses them.
The robot arm elegantly swivels towards the plate, picks a precise portion of the dough with its instrument like a bird, and places it in the intended nest of the tooth mould. The mould then quickly moves to the next work step. A foil is positioned over the tooth mould as a separating layer. A suitable counter piece immediately comes from above like a stamp, where the material should not stick. Now it gets loud: The enamel materials are formed with pressure and vibration. The same happens afterwards with dentin and cervical materials. Finally, the plastic mass is positioned in the middle of the mould and the counter mould for subsequent compaction.
Under pressure and temperature, the denture teeth are finally pressed in a single cast at a precisely defined time interval.
