How lifelike is the crown
How is a crown inserted?
A distinction is made between different types of crowns (post crown, veneer crown, jacket crown, etc.) and materials (gold, ceramic, zirconium, Plastic), depending on which tooth is to be crowned. What all variants have in common is that the affected tooth must first be ground by the dentist in order to be able to place the crown on the remaining tooth stump. The so-called preparation usually takes place under local anesthesia and is therefore painless for the patient. During preparation, it is often unavoidable that healthy material from the tooth also has to be removed in order to provide sufficient support for the crown. The visible part of the tooth - the natural tooth crown - is usually ground down to below the gumline.
How much tooth substance has to be removed depends not only on the type of crown and its material, but also on how deep the tooth is already damaged. It is important that a sufficiently thick layer of the tooth pulp (dentin) remains to protect the sensitive tooth nerve and to keep the tooth painless even after the crown has been inserted. If too much healthy tooth substance is removed, in the worst case even the root canal, which is supposed to protect the tooth root, can be affected. This in turn can result in painful root canal treatment or even death of the tooth.
When the tooth is completely prepared, the impression is taken.So that the crown margins fit exactly under the gum line later on, the gums are displaced with threads that are placed around the tooth stump and pressed into place. Then it's time to take an impression of the stump. This is usually done with an impression tray, which is filled with a special impression compound and then pressed firmly onto the entire jaw. The compound quickly hardens on the surface to such an extent that a usable impression is created, on the basis of which the tooth crown will later be created in the dental laboratory. An impression must also be taken of the opposing jaw in order to determine the height and shape of the artificial tooth crown.
The patient then receives a temporary that protects the sensitive tooth stump, protects the "construction site" from unwanted looks and ensures the chewing and speaking function until the laboratory has completed the dentures and the dentist can insert the tooth crown. This usually only takes a few days or weeks. The dentist then determines the tooth color (in the case of visible crowns made of ceramic or with a ceramic coating), because after all, the tooth crown should later fit harmoniously into the rest of the dentition and visually match the other teeth.
