Describe the composition of lithium disilicate, leucite reinforced, three
mol% yttria-stabilized zirconia polycrystal (3Y-TZP), and five mol% yttria-
stabilized zirconia polycrystal 5Y-ZP indirect restorative materials.
Compare and contrast the physical properties of each. This should include
a discussion of flexural and/or compressive strength, fracture toughness, and wear resistance.
Describe the clinical indications of each material described above. In
which clinical scenarios are each of the materials appropriate? Describe
any clinical contraindications for the previously described materials, as
well.
Describe the composition and physical properties of CAD/CAM hybrid
composite materials and the clinical indications for various CAD/CAM
hybrid composites.
