Influence of occlusal thickness and aging on the fracture load of additively manufactured definitive crowns in different resins

Journal of Prosthodontics, EarlyView.
Abstract Purpose The purpose of this in vitro study was to assess the effects of occlusal thickness and thermomechanical aging on the fracture load of additively manufactured (AM) definitive crowns made from resins with different compositions, compared with crowns subtractively manufactured (SM) from a polymer‐infiltrated ceramic network. Materials and

Testing coir (coconut) fiber as a novel, biodegradable material for coral reef restoration: coir interactions with larval and juvenile corals

Restoration Ecology, EarlyView.
Abstract Introduction Coral populations have declined in recent decades, largely due to anthropogenic climate change. In response, coral restoration projects are being implemented, and rubble stabilization is one such approach. Rubble beds form when dead coral fragments accumulate on the seafloor and can be mobilized by water flow.
