Correct answer: D — Acrylic denture base material
The correct answer is D. Polymethyl methacrylate is the principal polymer used in conventional acrylic denture base materials and is produced by polymerisation of methyl methacrylate monomer. Dental composite fillers are inorganic particles such as silica or glass; the resin matrix commonly contains dimethacrylates rather than PMMA. Glass ionomer cement is formed by an acid–base reaction between fluoroaluminosilicate glass and a polyacid. Zinc phosphate cement is based on zinc oxide powder and phosphoric acid liquid, while dental amalgam is a metallic material produced from an alloy powder and mercury.
