What type of cement is required for a fractured amalgam restoration when time does not permit permanent restoration?

In the case of a fractured amalgam restoration where immediate permanent restoration is not feasible, the appropriate choice is to utilize temporary cement to a secondary consistency. Temporary cement is specifically designed for short-term use, providing a sufficient bond to hold the fractured piece in place until a more durable, permanent solution can be applied later.

Using temporary cement allows for flexibility in managing the patient's dental needs quickly, which is essential in a situation where time is restricted. The secondary consistency refers to a thicker consistency of the cement, which enhances its ability to fill gaps and adhere effectively to the tooth structure and the fractured amalgam. This level of consistency ensures that the temporary restoration remains in place, providing adequate protection and functionality for the tooth until a definitive restoration can be performed.

Final cement is typically reserved for long-lasting, permanent solutions and would not be appropriate in a scenario where the goal is to secure a temporary repair. Additionally, a primary consistency of cement is generally thinner and more suited for different applications, making it less ideal for providing a secure, temporary hold on a fractured restoration.
