Effect of sintering cycle on the strength and translucency of multilayered zirconia

Journal of Prosthodontics, EarlyView.
Abstract Purpose A newly introduced sintering protocol promises to offer higher translucency while not significantly compromising the flexural strength of the material. However, the effect of the novel sintering protocol has not been thoroughly validated.

Assessment of fit accuracy and retentive strength of additively manufactured zirconia crowns luted to Ti‐base abutments with different resin cements: An in vitro study

Journal of Prosthodontics, EarlyView.
Abstract Purpose This study investigated the influence of cement gap size on the marginal and internal fit, and cement gap size and type on retention of additively manufactured zirconia (AM‐Z) crowns on titanium bases (Ti‐base). Materials and Methods A total of 135 zirconia crowns were designed with three different cement gap sizes: 20 µm, 30 µm, and ...
