Dentures are removable appliances to replace one or more missing teeth, or all the teeth in your upper or lower jaw
Types of Dentures: Main Categories
- Partial dentures
- when some teeth remain on the jaw (i.e. upper or lower jaw). Partial dentures can be acrylic (plastic) or metal.
- Complete dentures
- when there are no teeth remaining on that jaw.
- Immediate dentures.
Metal Denture-A metal-based denture is one in which a portion of the denture body is made of a substantial metal casting rather than all plastic (acrylic resin).
Advantages of metal-based dentures
- Very bio-compatible and hypoallergenic with healthy-appearing supporting tissues
- May include a soft liner
- Can be relined easily
- Provides added strength for easily broken narrow dentures
- Facilitates fabrication of stable narrow-based dentures that are designed to avoid contact with disrupting muscle forces
- Sometimes facilitates the avoidance of surgical procedures to reposition frenum
- Patients perceive a more natural feeling from the added weight
- Weight may contribute to additional denture stability
- Dimensionally very stable when compared to all-plastic-based dentures during fabrication and over time
Disadvantages of metal-based dentures
- Generally difficult to reline or repair standard metal-based dentures
- More costly to fabricate
