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.

Fibroblast and bacterial adhesion on a 3D‐printed polyetheretherketone‐based implant material

European Journal of Oral Sciences, EarlyView.
Abstract This study investigated fibroblast and bacteria proliferation on polyetheretherketone (PEEK)‐implant material 3D‐printed by fused deposition modeling (FDM) in comparison to titanium (cp‐Ti) and zirconia (ZrO2). Four groups were tested, including horizontally FDM‐printed PEEK (PH), vertically printed FDM‐PEEK (printed vertically [PV]), cp‐Ti ...

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.

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.
