Features of stamped crowns
The stamped crown was made of thin metal and did not fit tightly to the neck of the tooth, so caries almost always develops underneath it, and sometimes only the root remains. It is easier to remove than a cast one: the wall is thin, it can be cut and opened in a few minutes. After removal, the condition of the tooth must be assessed—canal treatment or root removal is often required.
Why are the stages counted separately?
Orthopedic treatment consists of clinical and laboratory stages. Some of them - taking impressions, making an individual tray, gum retraction, fixing or removing a crown - are performed independently and are not always included in the main work.
The result directly depends on the quality of these stages: an inaccurate impression or an under-opened edge of the ledge will lead to the fact that the crown will not fit, no matter how well it is made in the laboratory.
What affects accuracy
- selection of impression material for a specific task
- dry field and lack of blood in the ledge area
- correctly opened gingival sulcus
- no deformation of the impression during removal
