Grinding & Digital Impression.
After removal of caries, old fillings or possibly after root canal treatment, a 3D image of the tooth is taken directly at the treatment chair (chairside) using an oral camera (intraoral scanner). The advantage is that no impression material has to be used and the gag reflex experienced by many patients is thus eliminated.
The dental restoration is then digitally designed (CAD) in our own dental laboratory.
The ceramic milling unit mills the crown from an industrially prefabricated ceramic block (CAM). Consistent quality is ensured by the industrial production of the ceramic blocks. In contrast, ceramic crowns pressed or layered in the dental laboratory have a higher risk of fracture due to processing defects such as air inclusions, impurities or similar.
The finished milled restoration is placed promptly after checking the accuracy of fit and subsequent glaze firing.
In particularly difficult cases, such as multiple crowns or anterior teeth, a plaster model is fabricated after taking a conventional impression of the prepared teeth and subsequently photographed using a laboratory camera. Both procedures allow a 3D image to be created on the computer. Different brightness and color levels of the ceramic blocks allow the crowns to be perfectly matched to the patient's own tooth color.
