Denture materials

Cobalt chrome

For a partial denture, an alloy of cobalt and chrome can be offered as the base of the denture. It can generally be cast to a relatively thin shape so is less bulky in the mouth and covers less of the palate than acrylic dentures. Consequently the denture feels less invasive and food and drink is often enjoyed more. Acrylic is attached to the metal framework for an aesthetic finish.

Cobalt chrome dentures have extensions called clasps, which clip around the teeth at the back of the mouth. These are very rarely visible on smiling or talking but add a huge degree of retention and stability to your denture.

These types of denture generally last longer than acrylic dentures because they are made of such a strong material. They are more stress resistant and are less likely to bend or break.


Standard acrylic can be used to make either partial or complete dentures. It is a pink material so matches the natural shade of your soft tissue and is a good material to make the bulk of a denture. It is generally well resistant to damage and is the material of choice when the denture is predicted to need adjustment in the near future; due to the nature of the material it is very easy to add or remove teeth from the denture.

High-impact acrylic

High-implant acrylic dentures are even more resistant to impact than regular acrylic dentures, without sacrificing the high-quality aesthetics, so if you drop them they are less likely to break. They are also more resistance to flexion stress (one of the main reasons why dentures fail). During constant insertion and removal (sometimes on an axis) dentures can generate stress fractures. High-impact acrylic helps eradicate this problem, giving long lasting dentures. As with acrylic dentures, high-impact acrylic dentures are easily adjusted if teeth need to be added or removed.

Reline materials

One of the benefits of acrylic dentures is that they can easily be relined if they become loose over time or grow uncomfortable. As an emergency practice we are able to offer a one-day turnaround with dentures that need relining and will return them to the stable, comfortable way they should be within 24 hours. However, with a denture that needs continual relining it is worthwhile considering having a new denture made.

If you are unhappy wearing dentures consider having dental implants. Dental implants can
also stabilise loose dentures. Please call now for your free dental implant assessment.
