Tribology of polyetheretherketone

Wear, 1992
Abstract A comprehensive discussion of tribological performance of polyetheretherketone is presented. It is based on experimental results obtained in a series of studies carried out in order to assess the potential of the polymer as a material for sliding and rolling contacts.

Bond strength of lithium disilicate to polyetheretherketone

The Journal of Prosthetic Dentistry, 2022
Polyetheretherketone (PEEK) is a high-performance polymer that is increasingly used in dentistry, for example, as a framework for implant-supported fixed complete dentures. One protocol calls for individual lithium disilicate crowns to be cemented on preparation-shaped retentive elements on the framework.

pH-responsive silk fibroin-based CuO/Ag micro/nano coating endows polyetheretherketone with synergistic antibacterial ability, osteogenesis, and angiogenesis.

Acta Biomaterialia, 2020
Polyetheretherketone has been widely used for bone defect repair, whereas failures may happen due to implant loosening and infection. Thus, PEEK implant with multi-function (osteogenesis, angiogenesis, and bacteria-killing) is essential to solve this ...
