DENTURES

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.
• Overdentures.
• 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
