What are the two main types of provisional coverage available?

The two main types of provisional coverage available are custom and prefabricated. Custom provisional coverage refers to crowns or bridges that are individually crafted to fit a specific patient's dental arch and occlusion. These are made using materials that can be shaped and adjusted for the ideal fit, providing better aesthetics and function compared to other types.

On the other hand, prefabricated provisional coverage is manufactured in advance and comes in standard sizes. This type can be quickly used in clinical settings when time is of the essence, and while it may not fit as perfectly as a custom option, it serves the necessary temporary function during the period before a permanent restoration is available.

Understanding these types of provisional coverage is vital for dental assistants, as they play a key role in ensuring that patients receive the appropriate type of temporary restoration based on clinical needs and circumstances. The other choices, while they may reference types of dental work, do not accurately describe the recognized categories of provisional coverage used in dentistry.
