The New Zealand Dental Services
The establishment of masticatory efficiency of long duration in the least time was the primary consideration in the choice of filling materials. Most were of silver amalgam with a protective lining of cement. Where aesthetic demands precluded the use of amalgam, as in the case of anterior teeth, synthetic porcelain was used. The malleted gold filling and the gold inlay had no place in army practice, but inlays of acolite and of a gold-coloured metal called ‘Allcast’ were used occasionally.
