If you’re considering dentures for yourself, understanding the materials used in modern dentures is crucial. In this article, we’ll delve into what are dentures made of, their structure, and maintenance tips, shedding light on their importance in dental health and everyday life.

Understanding Dentures

Dentures, also known as dental prosthetics, are removable appliances designed to replace missing teeth and surrounding tissues. They serve both functional and aesthetic purposes, restoring the ability to chew, speak, and smile confidently. Dentures come in various types, including full dentures for complete tooth loss and partial dentures to replace several missing teeth while preserving existing ones.

What Are Dentures Made of

If you are curious about what dentures are made of? The materials used in modern dentures have evolved significantly, offering enhanced durability, comfort, and aesthetics. Traditionally, dentures were crafted from materials like porcelain, acrylic resin, and metal alloys. However, advancements in dental technology have introduced innovative materials that improve upon traditional options.

What Are Dentures Made Out of: The Base, the Framework and the Teeth

Dentures have different parts and each is made out of different materials. We could divide the structure of dentures into three parts: the base, the framework, and the teeth.

Regarding the base, dentures are made out of acrylic resin. This versatile material is commonly used for the base of dentures. Acrylic resin provides durability and flexibility, allowing for comfortable wear while ensuring a natural appearance. These materials also reproduce the look of your gums, making them look like your real smile

Contrary to the base, the framework can be made of several materials that create a sturdy framework offering additional support, ensuring a secure fit and longevity. Some of the materials used are:

  1. Cobalt-Chromium: Similar to partial denture frameworks, cobalt chromium is exceptionally strong and resilient, making it an excellent choice for the base of full dentures. It offers stability and longevity, ensuring the dentures remain in place and function effectively for an extended period.
  2. Titanium: Titanium is another material known for its strength and biocompatibility, making it suitable for dental applications. Full denture bases made from titanium are lightweight, corrosion-resistant, and can comfortably fit the wearer.
  3. Flexible Polymer: Similar to partial dentures, full dentures can also utilize flexible polymer materials such as Valplast. These dentures offer a natural-looking appearance and enhanced comfort because of their flexibility, allowing them to adapt to the contours of the gums.

Lastly, for the teeth, porcelain is still utilized for artificial teeth in dentures, although less common than acrylic resin. Porcelain closely resembles natural teeth in color and texture, providing a lifelike appearance, but acrylic teeth adhere more securely to the denture making them stronger than porcelain.

The materials used to make modern dentures today offer significant benefits over traditional options. Some of those benefits are the following:

  • They are lightweight, comfortable, and closely resemble natural teeth, boosting both appearance and confidence.
  • These materials are also biocompatible, meaning they are well-tolerated by the body, reducing the risk of irritation or allergic reactions.
  • Additionally, they are more durable, lasting longer, and require fewer replacements.

Overall, advancements in denture materials have led to prosthetics that are not only functional but also more natural-looking and comfortable for wearers.

Structure of Dentures

Understanding the structure of dentures is essential for proper fitting and functionality. As we have mentioned before, dentures consist of several components, including:

  • Base (for full dentures): The base of the denture, typically made of acrylic resin, provides support and stability. It is custom-fitted to the shape of the patient’s gums, ensuring a comfortable fit.
  • Artificial teeth: The artificial teeth, made of porcelain or acrylic resin, are carefully crafted to resemble natural teeth in size, shape, and color. They are attached to the base of the denture using a secure adhesive.
  • Connectors (for partial dentures): In partial dentures, connectors attach the artificial teeth to a metal framework or directly to adjacent natural teeth. These connectors ensure proper alignment and distribution of chewing forces.
Two images: on the left, full dentures, dentures base is the part that emulates the gums and the fake teeth. On the right, partial dentures. The connectors are the part that is the component of the partial denture that connects the parts of the prosthesis located on one side of the arch with those on the opposite side.

Denture Maintenance: How to Care for Them

Proper maintenance is essential to prolong the lifespan of dentures and ensure optimal oral hygiene. Here are some tips for caring for your dentures:

Clean them every day

Clean your dentures daily using a soft-bristled brush and mild denture cleaner. Avoid using abrasive materials or harsh chemicals, which can damage the denture's surface.

Take them out before bedtime

Take out your dentures before bedtime to give your gums and jawbone a chance to rest. Soak them in water or a denture-cleansing solution overnight to keep them moist and prevent warping.

Handle your dentures with care

Schedule regular dental check-ups to ensure your dentures fit properly and address any issues promptly. Your dentist can make adjustments or repairs as needed to maintain comfort and functionality.

Conclusion

In conclusion, modern dentures are crafted from high-quality materials that prioritize comfort, durability, and aesthetics. Understanding the composition and structure of dentures is essential for proper maintenance and long-term oral health. By following proper care guidelines and seeking regular dental check-ups, you can enjoy the benefits of dentures for years to come. Whether you’re considering dentures for yourself or assisting a loved one, knowing what dentures are made of today empowers you to make informed decisions regarding dental prosthetics.

FAQ

Why are dentures made from a material that can stain?

Teeth are usually made with acrylic resin, as mentioned before in the article. This material is porous to emulate the look and feel of real teeth, and that’s why foods and drinks (especially coffee) can accumulate and stain the teeth.

Which type of partial dentures would look the most natural?

Based on patients' satisfaction and professionals' opinions, the best looking are flexible partial dentures.

Do dentures glow under black light?

Dentures are not made to glow in black light; however, some can glow to some extent depending on the type of porcelain that you chose.

Can the materials used to make dentures cause an allergic reaction?

Dentures shouldn’t cause any allergic reaction; however, it can sometimes happen. Allergic reactions can be caused by biodegradation, under-processed free methyl methacrylate monomer, and allergy to dental resin-based materials, among other causes.

Should I choose acrylic, metal or valplast for dentures?

Choosing between these three materials will depend on the main goal of your dentures. If you want them to look as natural as possible, you should pick valplast dentures. But, if you want to get them as soon as possible, acrylic dentures might be the best solution. Regarding metal dentures, these are perfect when looking for comfort, as they are lightweight, and durability.
