Optimizing Hard and Soft‐Tissue Esthetics With Anterior Cantilever Zirconia Ceramic Resin‐Bonded Fixed Dental Prostheses

open access: yesJournal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective The replacement of missing maxillary lateral incisors poses both functional and esthetic challenges, not only from a restorative but also from a periodontal aspect. This case report presents a step‐by‐step protocol for ideal hard and soft‐tissue esthetics with cantilever zirconia ceramic resin‐bonded fixed dental prostheses (RBFDPs).

Color stability of precolored and extrinsically colored monolithic multilayered polychromatic zirconia: Effects of surface finishing and aging

open access: yesJournal of Prosthodontics, EarlyView.
Abstract Purpose To explore the impact of zirconia types, coloring methods, and surface finishing on the color stability of monolithic multilayered polychromatic zirconia after artificial aging, including thermocycling and simulated toothbrushing. Materials and Methods Eighty square‐shaped zirconia samples were divided into 2 types (M3Y‐TZP and M6Y‐PSZ)

Evaluation of shear bond strength based on substructure materials and ceramic veneering techniques

open access: yesJournal of Prosthodontics, EarlyView.
Abstract Purpose Bilayered restorations have both the strength of the substructure material and the esthetics of the veneer material; however, they should have appropriate bonding between the two materials. This study aimed to evaluate the shear bond strength (SBS) according to the substructure material and veneering technique used in bilayered ...

NASA thermal barrier coatings: Summary and update [PDF]

open access: yes
A durable, two-layer, plasma-sprayed coating consisting of a ceramic layer over a metallic layer was developed that has the potential of insulating hot engine parts and thereby reducing metal temperatures and coolant flow requirements and/or permitting ...

Effect of artificial aging on fracture toughness and hardness of 3D‐printed and milled 3Y‐TZP zirconia

open access: yesJournal of Prosthodontics, EarlyView.
Abstract Purpose This study aimed to evaluate the impact of artificial aging on the fracture toughness and hardness of three‐dimensional (3D)‐printed and computer‐aided design and computer‐aided manufacturing (CAD‐CAM) milled 3 mol% yttria‐stabilized tetragonal zirconia polycrystals (3Y‐TZP). Materials and Methods Forty bar‐shaped specimens (45 × 4 × 3
