Which of the following is NOT a type of occlusal and bite registration material?

Occlusal and bite registration materials are critical in dentistry for capturing the relationship between the opposing dental arches. Among the types of materials commonly used, wax, polysiloxane, and ZOE (zinc oxide-eugenol) paste are all recognized for their effective properties in making accurate bite registrations.

Wax is a traditional material that has been used for occlusal registrations due to its ease of manipulation and ability to capture fine details. Polysiloxane is a contemporary option that provides excellent dimensional stability and accuracy, making it a popular choice for many clinicians. ZOE paste can also be used for bite registration due to its ability to flow into small spaces and capture the occlusal contacts.

However, alginate is primarily known for making impressions, not specifically for occlusal or bite registrations. Alginate is a hydrophilic material that sets by a chemical reaction and is typically used to make impressions of the teeth and oral tissues, rather than to register the occlusal relationship. Therefore, while alginate is an essential material in dentistry, it does not fall under the category of occlusal and bite registration materials.
