What type of cement is frequently used to cement provisional crowns?

The choice of Type 1 ZOE (Zinc Oxide Eugenol) for cementing provisional crowns is based on its properties that make it particularly suitable for temporary applications. Type 1 ZOE is known for its ease of use, adequate strength, and sedative qualities, which can be beneficial for sensitive or irritated pulps. It helps to provide a comfortable fit for the provisional crown, allowing for a suitable temporary solution while a patient waits for a permanent restoration.

Moreover, Type 1 ZOE offers sufficient adhesion and is relatively easy to remove when it's time for the permanent crown placement, making it practical for provisional restorations. The consistency of Type 1 ZOE allows for a reliable bond without being overly rigid, thus avoiding potential damage to the underlying tooth structure when the provisional is removed.

In contrast, other options like modified glass ionomer and resin cement are more often used in permanent restorations due to their strength and bonding capabilities, which are not necessarily critical for temporary use. Type 2 ZOE, while also a potential option, tends to be used in different contexts such as for permanent cementation of crowns where higher strength is required. These considerations highlight why Type 1 ZOE is the most appropriate choice for provisional crown cementation
