What is most commonly used for taking a bite registration?

Alginate
Bite registration material
Plaster
Silicone

The correct answer is: Bite registration material

Bite registration is a common term used to describe the process of obtaining a registration of the relationship between the upper and lower teeth. This is necessary for fabricating dental restorations such as crowns, bridges, and dentures. While alginate, plaster, and silicone can all be used for bite registration, they are not the most commonly used material. Alginate is more commonly used for taking impressions of the teeth and other oral structures. Plaster is typically used as a model material for fabricating dental restorations, and silicone is commonly used in dentistry for taking impressions and making custom trays. However, bite registration material is specifically designed for this purpose, making it the most commonly used material for this specific task.
