What type of cement is used for temporarily securing a crown?

Temporary cement is specifically designed for securing crowns and other dental restorations on a short-term basis. It allows for easy removal of the restoration if necessary, whether for adjustments, repair, or permanent cementation. This is particularly important in cases where the dentist may need to assess fit, occlusion, or make any adjustments before final placement.

Permanent cement, on the other hand, is used for final restoration where a durable bond is needed, which makes it unsuitable for temporary applications. Glass ionomer cement, while it can be used for both permanent and temporary cementation, often provides a more long-term solution than what is required for situations where the crown is meant to be in place just temporarily. Composite resin is primarily used for cosmetic purposes and as a direct restorative material rather than for securing crowns. Therefore, the choice of temporary cement aligns perfectly with the requirements of securing a crown temporarily.
