temporary crown
A temporary crown (provisional crown, interim crown) is a temporary (short-term) crown used in dentistry. Like other interim restorations, it serves until a final (definitive) restoration can be inserted. Usually the temporary crown is constructed from a chemical-cure composite, although alternative systems using aluminium crown forms are occasionally used. Temporary crowns function to protect the tooth, prevent teeth shifting, provide cosmetics, shape the gum tissue properly, and prevent sensitivity.〔http://www.baselinedental.com/temporary-crown-fell-out/〕
A temporary crown will usually be cemented in place with a soft temporary dental cement. This allows for easy removal when fitting the permanent crown.
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. If a dentist cannot be seen in a timely manner, the temporary crown may be recemented by applying temporary cement to the temporary crown.
