Temporary crown
Encyclopedia
A temporary crown is a provisional, short term restoration used in dentistry
. Usually the temporary crown is constructed from a chemical-cure composite
, although alternative systems using aluminium
crown forms are occasionally used by practitioners. The temporary material is shaped by the dentist to form a tooth shape that protects the prepared tooth, prevents damage to the periodontal tissues (gums) and disguises the prepared tooth to a degree until the final, definitive restoration can be made by a dental technician
.
A temporary crown will usually be cemented in place with a soft temporary dental cement, such as Temp-Bond NE. This allows easy removal when fitting the definitve restoration.
If a temporary crown becomes decemented, it is important that a dentist examine the patient as overeruption
of the opposing teeth may prevent accurate fitting of the final crown

Overeruption
Overeruption is a term used in dentistry to describe the physiological movement of a tooth lacking an opposing partner in the dental occlusion. Because of the lack of opposing force and the natural eruptive potential of the tooth there is a tendency for the tooth to erupt out of the line of the...

Crown (dentistry)
A crown is a type of dental restoration which completely caps or encircles a tooth or dental implant. Crowns are often needed when a large cavity threatens the ongoing health of a tooth. They are typically bonded to the tooth using a dental cement. Crowns can be made from many materials, which...
