The effect of sintering time on the marginal fit of zirconia copings
Journal of Prosthodontics Apr 11, 2018
Khaledi AAR, et al. - Experts evaluated the impact of different sintering times on the marginal adaptation of zirconia ceramic copings. They included 3 groups viz IPS e.max ZirCAD, Speed ZrO2, conventional ZrO2. As per data, mean values for the marginal gap of the IPS e.max ZirCAD, Speed ZrO2, and conventional ZrO2 groups were 41.06 ± 14.03, 43.03 ± 11.67, and 39.88 ± 15.23 μm, respectively. Findings suggested that the marginal fit of the zirconia copings was not altered by different sintering times. For all 3 groups, the mean values of the marginal gap were within the clinically acceptable level.
