Design outcomes

Primary

MeasureTime frame
1.Total technical complications between monolithic zirconia and metal ceramic crown Sample size was calculated using the total technical outcomes of metal ceramic crown (27.1%) and zirconia crown (5.4%) obtained from a previous study, 80% power, 5% alpha error. The total sample size was 35 per group which was increased to 40 per group (total 80 patients) to adjust for 10% dropout.Timepoint: Baseline, 6 months, 1 and 3 year—

Secondary

MeasureTime frame
1. Survival analysis – between monolithic zirconia and metal-ceramic crown. 2. Comparison of the Plaque index (Rustogi Modification of Navy Plaque Index) and the Bleeding index (Ainamo and Bay).Timepoint: Baseline, 6 months, 1 and 3 year—
