This is the final step of the procedure.
A few weeks after the impressions usually about 2 weeks you will be asked to come back to have the final fit of the crown. During this appointment the clinician will try in the crown or bridge that has been sent back from the laboratory. They will initially just try it in and ensure it doesn't need any major changes. If they are happy with that then they will proceed to either cement retain the crown or to screw it in to permenantly place it.
The clinician will then check the bite and ensure that you are fully happy with it. Once everyone is satisfied you will be then finished.
