Question: 1 / 1775

What is the denture base made of?

Metal

Porcelain

Acrylic

The denture base is primarily made of acrylic materials due to their favorable properties that make them suitable for creating a comfortable and functional prosthesis. Acrylic resin is lightweight, easy to mold, and can be color-matched to simulate the appearance of natural gums, enhancing aesthetic appeal. Additionally, acrylic has adequate durability for everyday use in dentures, providing a balance between strength and flexibility.

Other materials listed, such as metal and porcelain, serve different purposes in dentistry. Metal is often used in frameworks for partial dentures for its strength and resilience, while porcelain can be found in denture teeth but is not used for the base due to its brittleness and heaviness. Glass is not a material used for denture bases, as it lacks the necessary properties to provide the comfort and fit required in dental prosthetics.
