Bimetallic ions regulated PEEK of bone implantation for antibacterial and osteogenic activities

Materials Today Advances, 2021
After the surgical implantation of polyetheretherketone (PEEK) orthopedic biomaterials, there are two major clinical challenges, implantation-related pathogen infection and poor osseointegration-caused aseptic loosening, threaten the lifespan and the ...

In vitro physicochemical and biological properties of titanium alloy, zirconia, polyetheretherketone, and carbon fiber-reinforced polyetheretherketone

Frontiers in Materials, 2022
Implant repair is a common means to restore the normal function of the hard tissues (bone or teeth). At present, the commonly and potentially used implant materials include titanium alloy (Ti), zirconia (Zr), polyetheretherketone (PEEK), and 30% carbon ...

VOA[$M$_4]

, 2020
We take a peek at a general program that associates vertex (or, chiral) algebras to smooth 4-manifolds in such a way that operations on algebras mirror gluing operations on 4-manifolds and, furthermore, equivalent constructions of 4-manifolds give rise ...

Evaluation of fracture resistance and color stability of crowns obtained by layering composite over zirconia and polyetheretherketone copings before and after thermocycling to simulate oral environment: An in vitro study

Journal of Pharmacy and Bioallied Sciences, 2020
Background: Most common material used for the fabrication of an implant restoration is full-ceramic crown or an all-ceramic crown. Frequent chipping of the ceramic under occlusal load has posed a great problem to the clinician and the patient. Composites
