Grinding & Digital Impression.
After removing the caries or the old amalgam filling, a 3D image of the tooth is taken directly at the treatment chair (chairside) using an oral camera (intraoral scanner). This has the advantage that no impression material needs to be used, and the gag reflex experienced by many patients is eliminated.
The dental restoration is then digitally designed (CAD) in our dental laboratory.
The ceramic milling unit mills the filling from an industrially prefabricated ceramic block (CAM), ensuring consistent restoration quality. In contrast, ceramic inlays or onlays pressed or layered in the dental laboratory have a higher risk of fracture due to processing errors such as air inclusions, impurities or similar.
The finished milled restoration is placed, i.e. bonded to the milled tooth, in the same session.
In particularly difficult cases, a plaster model is made following a conventional impression of the prepared teeth and subsequently photographed with 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 fillings to be perfectly matched to one's own tooth color.
