Results and disscusion. Mean time was of 305 seconds for triple tray, 527 seconds for one-step and 395 seconds for Cerec. Time for triple tray was shorter than for one-step and Omnicam. Patients’ evaluation (uncomfortable=0; comfortable=100) was of 64 for triple tray, 75 for one-step and 52 for digital, respectively. Differences were significant. Dentist’s evaluation (simple=0; very difficult=100) was 17 for triple tray, 58 for one-step and 41 for digital. Differences were significant.
