Prosthetic Resin Polymers
Prosthetic Resin Polymers
Demographic changes
•Means an increased need for Prosthetic treatments
Prosthetic Uses
- Denture bases
- Denture teeth
- Relining Materials
- Repair of dentures
- Provisional acrylic partial dentures
- Custom impression trays
- Mouth guards
- Fluoride and bleaching trays
- Facing on esthetical crowns
- Provisional restorations
- Removable tooth movement devices
- Orthodontic retainers
Denture base function
- •Distributes pressure over a wider area
- So reducing bone resorption
- •Retains artificial teeth
- •Replaces missing tissue
- •Forms a seal for retention
Denture Base materials
- •Carved ivory
- •Carved Wood
- •Vulcanite; dark, opaque (Vulcanised rubber)
- •Highly cross-linked Acrylic resin
- •Other Resin and plastic alternatives
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
- –After trauma
- –Surgical defects
- –Birth defects
- Other materials
- –Silicone rubber
- –Vinyls with plasticizers
Acrylic repair
•Materials
- –Chemically cured acrylic
- –Light cured acrylic
Record bases
- •Materials
- –Cold-curing acrylic resin
- –Other material
Other materials:
- •Polycarbonate
- •Aluminum
- •Stainless steel
- •celluloid
