Interior initiation and early growth of very high cycle fatigue crack in an additively manufactured Ti-alloy

open access: yes, 2022
Very high cycle fatigue of an additively manufactured Ti-6Al-4V is studied at R =-1, 0.1 and 0.2. The fracture surface of crack initiation and early growth region presents fine granular area (FGA) morphology with discon-tinuous regions of nanograins. The

Fracture load of cantilevered implant‐supported prostheses of varying heights fabricated from additively and subtractively manufactured resins

open access: yesJournal of Prosthodontics, EarlyView.
Abstract Purpose The purpose of this in vitro study was to evaluate the fracture load, both before and after aging, of implant‐supported cantilevered prostheses with different prosthesis heights fabricated additively using an experimental resin and a commercially available resin, or subtractively from a high‐impact polymer composite.

Effect of metal framework design on the fracture resistance of implant‐supported metal–ceramic crowns fabricated by selective laser melting

open access: yesJournal of Prosthodontics, EarlyView.
Abstract Purpose To evaluate the fracture resistance of implant‐supported metal–ceramic crowns fabricated using selective laser melting (SLM), according to the metal support height around the screw access hole (SAH) and the substructure design. Materials and Methods Metal–ceramic crowns and rectangular bilayer specimens were fabricated using SLM in two

Influence of woven ply degradation on fatigue crack growth in thin notched composites under tensile loading [PDF]

open access: yes, 2010
This paper deals with the fatigue of the through the-thickness crack propagation in thin notched composite laminates made of two glass woven plies. It highlights the different crack growths between warp and weft directions of the woven ply.

Peri‐implantitis—Is it mainly a clinician‐initiated complication of implant therapy?

open access: yesPeriodontology 2000, EarlyView.
Abstract Aim The high prevalence of peri‐implantitis is concerning, with a growing consensus that the majority of cases are complications initiated by clinician‐related errors rather than classic pathology. A primary predisposing factor for peri‐implantitis is exposure of the micro‐rough implant surfaces to the peri‐implant sulcus after treatment ...
