Physical Properties of Polyamide-12 versus PMMA Denture Base Material

Table 2

Modulus of elasticity (MPa) of polyamide-12 specimens (𝑛=15). Modulus of elasticity of dry specimens after delivery from the dental laboratory differed significantly from values after 1000, 3000, and 7000 thermocycles and wet storage.

MPa	After delivery; (dry storage)	After 1000 thermocycles; (wet storage)	After 3000 thermocycles; (wet storage)	After 7000 thermocycles; (wet storage)
