Acrylic Teeth on RPD Framework
Posted on 02/28/2012
Acrylic (plastic) teeth are the most common type of denture teeth used on partial denture frameworks. There are several reasons for this including:
1. Acrylic teeth chemically bond to the denture base resin creating a long and durable denture.
2. Modification and adjustment can be made without loss of retention or strength because the teeth are bonded to the denture base.
3. Acrylic teeth do not wear on opposing enamel
4. A range of price options are available from low end to high end. Popular brands of high end acrylic teeth include Dentsply Portrait IPN, Bioform and Ivoclar Blue Line.
There are some disadvantages of the acrylic tooth that should be noted. These include:
1. Economic (inexpensive) teeth tend to discolor with time
2. Teeth will show wear with time which results in poor chewing function. For example, a patient may find chewing meats difficult with acrylic teeth. Porcelain teeth are more suitable for such function and we will discuss their advantages and disadvantages in a later post.
