Ultra‐High‐Speed Sintering of 3.5Y‐TZP Zirconia: Time Reduction Without Compromising Translucency

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objectives To assess, firstly, the impact of three sintering speeds on translucency and grain size of 3.5Y‐TZP zirconia (Katana HT) across clinically relevant thicknesses, and secondly, the effect of thermocycling on translucency. Materials and Methods Disc specimens were fabricated at six thicknesses (0.7–2.0 mm) and sintered using SLOW (7 h),

Effect of material, prosthesis height, and aging on the fracture strength of additively and subtractively manufactured implant‐supported cantilevered prostheses

Journal of Prosthodontics, EarlyView.
Abstract Purpose This study aimed to evaluate the inherent and after cyclic loading fracture strength of implant‐supported cantilevered fixed prostheses fabricated from recently introduced additively manufactured (AM) and subtractively manufactured (SM) materials, considering variations in prosthesis height.

Engineered surface strategies to manage dental implant‐related infections

Periodontology 2000, EarlyView.
Abstract When exposed to the oral environment, dental implants, like natural surfaces, become substrates for microbial adhesion and accumulation, often leading to implant‐related infections—one of the main causes of implant failure. These failures impose significant costs on patients, clinicians, and healthcare systems.

Emerging locally delivered antimicrobial and immunomodulatory approaches for the prevention/treatment of peri‐implant diseases

Periodontology 2000, EarlyView.
Abstract Peri‐implant diseases are dysbiosis‐mediated inflammatory disorders that occur in susceptible hosts. Antimicrobials and immunomodulatory agents therefore might be pertinent as adjunctive measures in the treatment of such disorders. The aim of this narrative review was to examine the existing evidence and assess the effectiveness of emerging ...

Understanding exosomes in facial esthetics and skin aging

Periodontology 2000, EarlyView.
Abstract Background Skin aging is a multifactorial process mediated by intrinsic (genetic and metabolic) and extrinsic (environmental) factors leading to functional and structural deterioration, including wrinkles, loss of collagen and elastin, as well as various pigmentation disorders.
