Replicating the appearance of a natural, healthy mouth is a challenge for dentures. Although many of the materials used in dentures can be similar the appearance of your teeth and gums, they don’t look exactly the same. And the problem gets worse when dentures are completely made out of the same material. Although there may be benefits to using just one material for the denture, there is also a major drawback: cosmetics.
If you are looking for the most attractive and natural dentures, then you want dentures that are made out of a combination of materials: ceramics for the teeth and plastic for the gums.
Ceramics Make the Best Teeth
If you are looking for the most attractive denture teeth, then you want them to be made of ceramic material. Ceramics can be glossy and smooth like natural tooth enamel. They can achieve the layered, translucent effect that reflects the way your natural teeth grow with accumulating layers.
Ceramic teeth can also maintain their appearance for a long time. They are resistant to staining and wear, so they can be attractive for years.
Plastic teeth, on the other hand, never achieve the proper luster for teeth. They always look a little dull and don’t get the proper surface appearance.
And even if they do look acceptably shiny when polished, that doesn’t last. Plastic teeth are soft, and they can wear down. This means that they can lose not only height but also polish. They can grow dull in color. And they are vulnerable to stains. These teeth can become discolored fairly quickly if you eat and drink with them in–and if you don’t, what are they for?
But PMMA Makes for a Natural Base
On the other hand, PMMA--polymethylmethacrylate–can make for a very good base for dentures. That’s because PMMA is more like gum tissue, which is dull, not shiny, and has a different kind of translucency.
If ceramic is used for the base, it looks too glossy and unnatural. It can’t achieve the right kind of depth for gum tissue.
However, it’s important to get a dense, quality PMMA for the base, since this can resist staining and odors.
But Is PMMA Strong Enough?
One of the selling points used to promote all-ceramic dentures is that PMMA isn’t strong enough for the force of chewing. It’s true that ceramics are stronger, but you don’t always need the strongest material for your dentures.
If the forces in your bite are properly balanced, then a high-density PMMA base that is properly fortified should be strong enough, even with dental implants. You don’t have to make a choice between aesthetics and durability–you can have both.
