Design outcomes

Primary

MeasureTime frame
Monolithic Polished zirconia may produce significantly less antagonist enamel wear than Monolithic glazed zirconia and metal-ceramic crownsTimepoint: 1 year—

Secondary

MeasureTime frame
Monolithic Glazed ceramic may show the highest wear once glaze is lost clinically.Timepoint: 1 year; Monolithic Polished zirconia is expected to be the most enamel friendly and durable restorative option for posterior crownsTimepoint: 1 year—
