When would a crown restoration be Required/created?
In cases where the surface of the tooth crown can’t be fixed either by filling nor inlay / onlays or in order of better protection it’s more convenient to cover the tooth fully, then it’s done by crown. It is possible that we are using a tooth crown not only in terms of functionality, but also aesthetic reasons, whether in the case of an axis correction, or due to the large amount of old, discoloured fillings at the front.
What types of crowns are there?
They can be from different materials:
How are crowns prepared?
- Having examined X-ray of the tooth root and surrounding tissue condition and we decide together with the patient, what type of crown we are going to use, and why, then we are ready to anesthetize the particular area.
- The tooth is prepared by various grinding tools, we call it “shoulder preparation”. A shoulder preparation is the latest polishing process and forming the proper thickness of the edge for the future used crown which will fit the prosthesis without any gaps.
- Between the gum and the tooth we place yarn which was soaked by a bleeding palliative, which keeps the gum away from the tooth and makes the flange visible and prepared for the impression material
- Impressions will be taken of both sides of the jaw.
- Fixing the bite form.
- Choose the colour of the prosthesis.
- Prepare the temporary prosthesis.
- The dental technology prepares the prostheses, which are tested and checked in different phases in the mouth
- The finished prostheses fixed by cement temporarily or permanently in the mouth.
What do you need to do during the treatment?
- While the anesthetic begins to take effect, don’t chew.
- If a temporary or permanent prosthesis is uncomfortable, high, thick, etc…Inform your dentist
- If you have extremely sensitive teeth or hurts, Inform your dentist
- If the temporary prosthesis drops off, try to fix it by yourself and contact your dentist
- Always show up in rehearsal, because without it there is not possible to prepare a proper prosthesis
- Always follow oral hygiene instructions and have the crown status checked once a year, long-term warranty can be taken only in this case of prosthesis
