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 ...

Rapid sintering of 1.5 mol% yttria stabilized 3D-printed zirconia

European Journal of Materials
The widely use of 3 mol% yttria stabilized zirconia (3YSZ) in technical applications is driven by the toughening effect provided by the tetragonal to monoclinic phase transformation during mechanical loading.

Atomically ordered solute segregation behaviour in an oxide grain boundary

Nature Communications, 2016
Solute segregation is challenging to experimentally identify at the atomic scale. Here, the authors report the direct observation of atomic site-dependent solute segregation behaviour in an yttria-stabilized zirconia grain boundary by atomic-resolution ...

A digital workflow for full‐arch implant fixed prosthesis: Clinical application of a 3D‐printed polychromatic flangeless trial denture, anatomic bone reduction guide, and intraoral scanning for definitive prosthesis fabrication

Journal of Prosthodontics, EarlyView.
Abstract This clinical report presents a comprehensive digital workflow for rehabilitating a patient with maxillary terminal dentition using a full‐arch, implant‐supported fixed dental prosthesis (FP‐1). It highlights the integration of a 3D‐printed polychromatic flangeless trial denture and a customized anatomic bone reduction template, enabling ...

Effects of gastric acid on surface roughness, microhardness, fracture strength, and color change of dental ceramics: A systematic review of in vitro studies

Journal of Prosthodontics, EarlyView.
Abstract Purpose This systematic review evaluated the effects of simulated gastric acid (SGA) on surface and mechanical properties of dental ceramics to answer the research question: Does immersion in SGA alter the surface roughness, microhardness, fracture strength, and color of dental ceramics?

The effects of material thicknesses and substrates on the translucency and color masking ability of additively manufactured definitive crown materials

Journal of Prosthodontics, EarlyView.
Abstract Purpose To investigate the translucency of the new 3D‐printable materials concerning thickness and the color masking ability of each material against different substrate colors. Materials and Methods Ninety square‐shaped specimens (12.0 mm × 12.0 mm) of two new 3D‐printable materials: ceramic‐infiltrated hybrid resin composite (VS) and light ...

Does treatment‐induced surface roughness of 3 mol% yttria‐stabilized tetragonal zirconia polycrystals influence the wear of opposing restorative materials? An in vitro study

Journal of Prosthodontics, EarlyView.
Abstract Purpose This study aimed to investigate whether different surface treatments applied to 3 mol% yttria‐stabilized tetragonal zirconia polycrystals (3Y‐TZP), with comparable mean roughness (Ra) values, result in comparable values of additional surface roughness parameters, and to evaluate the influence of zirconia surface topography on vertical ...
