An abutment for a bridge uses two or more teeth to fill the toothless space. An abutment is a prepared tooth. This is a plastic widely used in dentistry for various purposes.
Acrylic resin is used in making impression trays.
Acrylic veneer is a tooth-colored layer of plastic placed over the surface of a crown or tooth. Once a tooth is prepared for a crown, a temporary crown is placed in the mouth. This is fabricated through a direct technique performed by your dentist. The acrylic temporary will provide similar function while your permanent tooth is being made. In this case, a heat and pressure cured acrylic is used.
