Polyetheretherketone bioactivity induced by farringtonite

Scientific Reports
AbstractPolyetheretherketone (PEEK) is considered as an excellent biomaterial for bone grafting and connective tissue replacement. The clinical potential is, however, limited by its bioinertness, poor osteoconduction, and weak antibacterial activity.

Acrylonitrile Styrene Acrylate (ASA) With Optimized Aluminum Oxide (Al2O3) Nanofiller Content for MEX Additive Manufacturing: Thermomechanical, Rheological, and Quality Metrics

Polymer Composites, EarlyView.
Characterization processes for ASA/Al2O3 nanocomposites in MEX 3D printing. ABSTRACT As additive manufacturing (AM) continues to expand, the demand for durable components for outdoor applications is increasing. Acrylonitrile styrene acrylate (ASA), a weather‐resistant polymer, is widely used in these applications, and improving its performance could ...

Nonthermal plasma approaches for combating implant‐associated infections: A compendious review

VIEW, EarlyView.
Implant‐associated infections pose serious clinical challenges. Non‐thermal plasma (NTP) modifications overcome this bottleneck in distinct ways relative to traditional sterilization methods. Gas‐phase plasmas generate highly energetic species, UV radiation and reactive oxygen/nitrogen species (RONS), which alter the implant surface properties.

Temperature Influence on the Creep Behavior of a Carbon Fiber/Polyetheretherketone Composite [PDF]

Journal of Applied and Computational Mechanics
Carbon/PEEK Fiber Composites materials have, generally, a viscoelastic behavior and the mechanical properties are time dependent. These materials have gained an explosive use in the last decades, hence the need to determine their mechanical properties as

Progress in bone tissue engineering biomaterials: Development, challenges, and prospects

VIEW, EarlyView.
Scheme 1 Application of biomaterials in immunomodulation during bone tissue engineering. Abstract Bone defect repair remains a major clinical challenge in orthopedics. Over 2 million cases caused by trauma, tumors, and other factors occur annually, with large‐scale defects posing a particular bottleneck due to limited self‐healing capacity.

Dual-functional sulfonated PEEK implants via graphene oxide–mediated BMP-2 gene delivery: enhanced osteogenic and antibacterial performance in vitro

Frontiers in Medicine
IntroductionPolyetheretherketone (PEEK) is a promising orthopedic implant material due to its bone-mimetic mechanical properties; however, its bioinert surface and susceptibility to bacterial colonization limit its clinical efficacy.

Segmented Intraoral Scanning With a Palatal Marker for Complete‐Arch Digital Implant Impressions: An In Vitro Comparative Study

Clinical Oral Implants Research, EarlyView.
ABSTRACT Objectives To compare four complete‐arch implant impression workflows—segmented right/left IOS merged via a palatal marker (IOS‐LEGO‐Seg), continuous full‐arch IOS with a palatal marker (IOS‐LEGO‐Full), continuous full‐arch IOS without a palatal marker (IOS‐Full), and a conventional open‐tray PVS impression followed by cast fabrication and ...

Marginal gap of printed, milled, and heat‐pressed two‐piece polyetheretherketone abutments before and after thermal cycling, and their pull‐off bond strength after thermal cycling

Journal of Prosthodontics, EarlyView.
Abstract Purpose To evaluate the marginal gap of two‐piece polyetheretherketone (PEEK) abutments fabricated with different methods, before and after thermal cycling, while also focusing on their pull‐off bond strength. Materials and Methods A two‐piece abutment was virtually designed after digitizing a titanium‐base (Ti‐base) abutment.
