Abstract:

BACKGROUND: Temporary crown has been used widely in clinic. The physical properties and biological safety of temporary crown and cement materials are more superior along with the development of material science.
OBJECTIVE: To summarize clinical application, physical properties and biological safety of the temporary crown and cement materials.
METHODS: PubMed database was searched by the key words of “temporary crown, provisional crown, temporary restoration, provisional restoration, interim restoration” in English to retrieve relevant articles published from January 2004 to December 2014. Literatures addressing the temporary crown and cement materials were included, and the repetitive researches were excluded.
RESULTS AND CONCLUSION: Through the clinical evaluation and experimental study, the physical properties (polymerization shrinkage, polymerization heat production, polymerization monomer release) and biological safety (cytotoxicity, irritation to the soft tissue) of the temporary crown and cement materials are the key problems needed to overcome. With the appearance of new materials and new fabrication methods, the temporary crown and adhesive materials have great application prospect and higher clinical value, but in the exploration process of the laboratory research and clinical application, there are many problems to be solved.
