Plastic acrylic teeth
  • •Bind chemically to the denture
  • •Can be adjusted
  • •Not cause wear of opposing tooth
  • •Good colour match
  • •Minor resiliency
  • •Wear under high force occlusion
  • •May stain with time
Other  Teeth Materials
  • •Porcelain (high fusing ceramic)
  • •Isosit (composite; xlinked acrylic) – heavily xlinked
  • •Experimental fiber-reinforced teeth
Maxillofacial prosthesis
Needed
