title: Radiographic stress measurement of two metal ceramic gold alloys.
abstract: A study was conducted to determine if radiographic stress measurement during the fabrication of a metal ceramic crown on gold alloys was possible. Stress in the longitudinal direction was radiographically calculated in the cast specimens (6 mm X 18 mm) after casting, sandpaper polishing, oxidation, and each firing process. Samples were also examined by x-ray diffraction. The results confirmed that radiographic stress measurement is possible for alloys with 70% to 80% gold content.
