Which material is commonly used for creating temporary crowns?

Polycarbonate is widely used for creating temporary crowns due to its favorable properties. It is a type of plastic that is strong yet easily moldable, making it an ideal choice for temporary applications in dentistry. The material allows for a quick and efficient process in which a temporary crown can be fabricated in the dental office or clinic, providing a patient with a functional and aesthetically pleasing solution while awaiting a more permanent restoration.

Additionally, polycarbonate can be readily adjusted or modified as needed during patient visits, ensuring a good fit and comfort. Its optical qualities are also suitable for temporary crowns, allowing for a natural appearance that blends well with the surrounding teeth. The other materials mentioned, while useful for permanent restorations or different dental applications, do not offer the same balance of ease of use, adjustability, and cosmetic appearance as polycarbonate for temporary crowns.
