What are ceramic crowns?
A ceramic crown is a crown made of tooth-colored ceramic material, which is placed over the defective tooth like a cap in case the tooth is so destructed that it cannot be saved by a dental filling.
Indications for ceramic crowns
Ceramic crowns meet the highest aesthetic and functional requirements. Based on our many years of experience in this field, we can offer you solutions for almost all types of crowns.
Possible applications:
- massively decayed teeth (caries)
- restoration after root canal treatment
- crown fracture
- missing tooth contacts (food residues get stuck in the gaps)
- implant restoration
- bite corrections
Advantages of a ceramic crown
Metal-free restoration
Perfect aesthetics
Excellent long-term prognosis
Tongue feel like that of a natural tooth
Low plaque adhesion
Healthy tooth structure is preserved
Course of treatment
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.
Digital design
The dental restoration is then digitally designed (CAD) in our own dental laboratory.
Digital fabrication
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.
Insertion
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.
FAQ
CAD/CAM refers to digital, i.e. computer-assisted methods for the fabrication of dental restorations. CAD stands for "computer aided design" and means the computer-aided design or construction of dental prostheses. CAM stands for "computer aided manufacturing" and means computer aided production, i.e. milling of dental prostheses. Due to our in-house dental laboratory, we are able to produce dental prostheses in this way with high quality, accuracy and speed, so that you have to wait less time.
