Enamel Wear. In vivo studies on enamel wear opposing a monolithic zirconia crown found that average vertical wear of the enamel antagonist was considerably higher than the contralateral enamel controls at the same time interval [3, 74, 75].A higher wear rate during the first 6 months suggested an initial runningin period followed by more steady wear afterward.
The starting materials used were highpurity monoclinic zirconia (TZ0 Tosoh Co., Tokyo, Japan, particle size nm, ... The effect of the starting powder composition on the sintering of tetragonal zirconia was studied. The beadmilling process was also studied and optimized. The fully dispersed and wellmixed suspensions were slipcast.
