Flashcards in Chapter 16: Vocabulary Deck (11):
1

a long-chain, high molecular weight molecule produced by the linking of many low molecular weight monomer molecules

Polymer

2

low molecular weight molecules that are joined to form polymers; as used in dentistry, monomers are usually liquids

Monomer

3

the act of forming polymers; the process can be activated by chemicals, heat, or light

Polymerization

4

common form of polymerization for dental materials; monomer molecules are added one to another sequentially as the reactive group on one molecule initiates bonding with an adjacent monomer molecule and frees another reactive group (free radical) to repeat the process

Addition Polymerization

5

a reactive group on one end of a monomer that initiates the joining of adjacent monomer molecules to form a polymer

Free Radical

6

a polymer composed of numerous methyl methacrylate monomers linked together into a long chain

Poly (Methyl Methacrylate)

7

liquid added to acrylic resin to soften it and make it more pliable

Plasticizer

8

numerous microscopic holes or voids within a material; often caused during polymerization of resins when monomer vaporizes and is lost; can also be caused by entrapping of air during mixing of powder and liquid

Porosity

9

a device used for the replacement of missing tissues. It can serve both cosmetic and functional roles

Prosthesis

10

a soft liner that is used in patients who have problems with hard acrylic denture bases; it is expected to last for 1 to 3 years

Long-Term Soft Liner

11

a soft provisional liner used to improve tissue health; also called a tissue conditioner; typically, it lasts from a few days to a few weeks

Short-Term Soft Liner
