To perform the dental crown procedure, your dentist prepares the tooth and makes a molded impression of the teeth to send to a dental laboratory. A fitted, temporary crown is created during this visit to temporarily protect the tooth while the final restoration is being made in the dental laboratory. Once completed, the crown can be cemented or adhesively bonded at a later visit.
A recent technology that we have, CAD/CAM technology (computer-aided design/manufacturing technology) has evolved to display a 3-D picture of the teeth. A restoration is then created through milling of a ceramic block. If this technology is located in the dental office (chair-side CAD/CAM), there will be no need for a temporary or return visit for the final cementation.
