An Investigation of Enamel Wear Opposing
Procera® AllCeram Aluminium Oxide Core
Wilson et al
Fifteen samples of Procera® AllCeram core material were tested against enamel in a custom wear apparatus with human saliva. Silicone impression techniques were used to record the before and after sample profiles. Measurements with a stereomicroscope (64x) showed that wear for the abraded samples ranged from 90 + 180 mm, 15-60 mm for the polished and 210-315 mm for the glazed. When the Procera® aluminium oxide core is exposed and in contact with enamel, wear is reduced when the surface is polished with Brasseler Dialite System.
