Effects of printing temperature and post‐curing duration on the dimensional reproducibility and fracture load of 3D‐printed dental prostheses: An exploratory study

open access: yesJournal of Prosthodontics, EarlyView.
Abstract Purpose This in vitro study aimed to evaluate the effects of printing temperature and post‐curing duration on the dimensional reproducibility and mechanical properties of three‐dimensional (3D)–printed dental prostheses. Materials and Methods Photopolymer specimens were fabricated using a stereolithographic 3D printer at two temperatures: room

Surface properties and biofilm formation of a manufacturer‐reinforced, nanographene‐modified pre‐polymerized CAD‐CAM polymethylmethacrylate denture base material: An in vitro study

open access: yesJournal of Prosthodontics, EarlyView.
Abstract Purpose To evaluate the surface roughness, hydrophobicity, and Candida albicans biofilm formation of three denture base materials, including two computer‐aided design and computer‐aided manufacturing (CAD‐CAM) polymethylmethacrylate (PMMA) resins and one conventional heat‐polymerized PMMA, before and after thermocycling (TC).

Pressed lithium disilicate glass ceramics: Microstructural characterization, in vitro and in silico nonlinear dynamic analysis for biaxial flexural strength

open access: yesJournal of Prosthodontics, EarlyView.
Abstract Purpose To evaluate the mechanical properties of lithium disilicates, and to assess the predictive capability of in silico models for biaxial flexural strength (BFS). Materials and Methods Specimens of four heat‐pressed lithium disilicates (IPS e.max Press, Rosetta SP, LiSi Press, Vintage Prime Press) were obtained.

3D assessment of the marginal and internal gap and fracture load of ceramic surveyed inlays designed for removable partial denture support: An in vitro comparative study

open access: yesJournal of Prosthodontics, EarlyView.
Abstract Purpose To assess the internal and marginal gaps and the fracture load of different machinable ceramics for an inlay acting as a support for a removable partial denture. Materials and Methods Sixty extracted human teeth (first maxillary premolar) were collected (n = 10 for each group).

Spatial and temporal evolution of a coastal erg margin: the Middle Jurassic Page Sandstone, southern Utah, USA

open access: yesSedimentology, EarlyView.
ABSTRACT Aeolian deflationary events are erosive to static stages where sediment supply is insufficient to support bedform migration and preservation in the rock record. In the vicinity of shallow‐marine environments, inland rises of relative water table and associated generation of deflationary super surfaces may be driven by the onset of ...

Cenozoic tropical carbonate platforms in the Santos Basin, SE Brazilian Margin

open access: yesSedimentology, EarlyView.
ABSTRACT Tropical carbonate platforms accompanied the latitudinal shifts of the tropical belt throughout the Cenozoic. Their flat‐topped geometries were influenced by a specific set of processes, including climate and sea‐level changes, carbonate facies, tectonics and continental runoff.

Fish Scales: A Multifunctional Biomaterial from Nature

open access: yesENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 5, September 2026.
Fish scales demonstrate nature's solution to impact protection through overlapping multilayered architecture. This biological design combines mineralized surfaces with collagen networks to achieve both flexibility and fracture resistance. The structural principles inspire advanced protective materials and biomedical implants, where damage tolerance ...
