Some physical and mechanical properties of shellac dental baseplate material.
The historical and general use of shellac is discussed and its particular value in dentistry outlined. The effects of variations in the mica and aluminium content of shellac are evaluated. Measurements of elastic modulus, modulus of rupture and glass transition temperature are reported.
