What are overdentures and how are they different from standard dentures?

Introduction

Dentures have been a reliable solution for tooth loss for centuries, offering both functional and aesthetic benefits. But as dental technology continues to evolve, so do the types of dentures available. One of these newer innovations is overdentures. If you’re wondering what overdentures are and how they differ from standard dentures, this blog post will provide all the insights you need.

What Are Overdentures?

Overdentures, also known as overlay dentures or snap-in dentures, are a type of removable denture that is supported by and attached to either a few remaining natural teeth or dental implants. Unlike standard dentures, which rest solely on the gums, overdentures use the support of natural teeth or implants to provide improved stability, comfort, and function.

How Do Overdentures Work?

In the case of implant-supported overdentures, two or more implants are placed in the jawbone. Once healed, attachments are fitted to these implants, which then connect to corresponding attachments on the overdenture. This ‘snap-in’ functionality ensures the overdenture stays in place while eating and speaking, while still allowing for easy removal for cleaning and maintenance.

For those with a few healthy natural teeth left, overdentures can also be supported by these teeth after they’ve been prepared by a dentist. This not only aids in retention and stability but also helps preserve the jawbone, preventing the bone loss often associated with complete tooth loss.

Standard Dentures vs Overdentures

So how do overdentures differ from standard dentures? Here are some key differences:

1. Stability and Comfort

One of the main advantages of overdentures is their increased stability compared to standard dentures. Because they’re secured to implants or natural teeth, overdentures are less likely to slip or move around, offering a more comfortable and worry-free experience for the wearer.

2. Preservation of Jawbone

Standard dentures rest on the gums, which can lead to the gradual loss of jawbone over time. Overdentures, especially those supported by implants, can help preserve the jawbone and maintain facial structure.

3. Lifespan

The lifespan of dentures varies depending on the type and care taken. According to the official guide ‘Everything You Need to Know About Dentures’ from the Denture Directory, standard acrylic dentures last 1–3 years, high-impact acrylic dentures last 3–5 years, chrome dentures endure 8–12 years, while flexible dentures, such as Valplast, last 3–5 years.

While the lifespan of overdentures can vary, with proper care and maintenance, they can often last longer than standard dentures due to their durable design and the use of dental implants.

Conclusion

Overdentures represent a significant advancement in denture technology, offering improved comfort, stability, and oral health benefits over standard dentures. However, as with any dental treatment, it’s essential to consult with a dental professional to determine the most suitable option for your specific needs.
