The metallic-ceramic crown is made of two parts: a metallic frame and a ceramic layer which covers it. The crown is fixed on the dental prosthetic pillar, so that only the part covered by ceramic is visible. It is a highly resistant work providing a natural aspect due to the ceramic layer. Unfortunately, once the time passes, the gum has the tendency to draw back, so, at a certain point, a unpleasant darker line will appear under the gum. This is why the metallic-ceramic crown is recommended for the works performed in the cheek bones’ lateral areas.
Which are the advantages of metallic-ceramic crowns?
Firstly, these crowns are perfectly biocompatible and highly resistant in terms of mechanical strength. Also, they are characterized by high durability in time, including here the colour of the dental work. They are extremely competitive from aesthetical point of view.
Which are the disadvantages of the metallic-ceramic crowns?
A darker line will always appear under the ceramic layer due to the metallic frame.
The tooth will undergo serious treatments before assembling the crown, such as the pulp tissue rejection and teeth grinding to allow fixing the crown.
How does the metallic-ceramic crown assembly take place?
This is a complex work which requires several treatment sessions. For the beginning, the teeth are grinded and printed and the imprint(s) is/are sent to the dental technician’s laboratory.
Based on the imprint, the technician makes the metallic frame which provides the resistance of the prosthetic work.
The metallic frame is then sent to the dentist who tests it and takes a new sample from the patient.
During the following treatment session, the new dental crowns will be fixed on the teeth which have been previously grinded.
