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.

Analysis of whisker-toughened ceramic components: A design engineer's viewpoint [PDF]

, 1989
The use of ceramics components in gas turbines, cutting tools, and heat exchangers has been limited by the relatively low flaw tolerance of monolithic ceramics. The development of whisker toughened ceramic composites offers the potential for considerable

Peri‐implant tissue definition and registration with a 3D‐printed emergence profile former on titanium stock healing abutment: A dental technique and clinical report

Journal of Prosthodontics, EarlyView.
Abstract Recent focus has shifted toward refining the soft tissue emergence profile to enhance aesthetics, support peri‐implant health, and ensure long‐term success. Traditionally, titanium stock healing abutments or chairside‐customized abutments were used to shape peri‐implant tissues and develop the emergence profile for implant‐supported prostheses.
