“…PEEK can be used for fixed dental prostheses (FDPs), for example, being made into crowns [ 12 ], frameworks, posts and cores, etc. Schmeiser et al [ 24 ] simulated the effect of the geometry of milled crowns (PEEK, PMMA, and silicate ceramic (SiO 2 )), crown-abutment material combinations, and thermal loading on the in vitro wear of crown materials during mastication and found that thermal loading did not affect material loss.…”

“…However, fewer reviews have comprehensively summarized the research advances in PEEK for a variety of dental applications. The stiffness of PEEK may not be sufficient to withstand load-bearing stresses [ 12 ] and there is a higher risk of fracture. However, PEEK can be blended with materials such as fibers and ceramics to improve its mechanical strength and provide advantages in various dental applications.…”

Polyetheretherketone (PEEK) is a thermoplastic material widely used in engineering applications due to its good biomechanical properties and high temperature stability. Compared to traditional metal and ceramic dental materials, PEEK dental implants exhibit less stress shielding, thus better matching the mechanical properties of bone. As a promising medical material, PEEK can be used as implant abutments, removable and fixed prostheses, and maxillofacial prostheses. It can be blended with materials such as fibers and ceramics to improve its mechanical strength for better clinical dental applications. Compared to conventional pressed and CAD/CAM milling fabrication, 3D-printed PEEK exhibits excellent flexural and tensile strength and parameters such as printing temperature and speed can affect its mechanical properties. However, the bioinert nature of PEEK can make adhesive bonding difficult. The bond strength can be improved by roughening or introducing functional groups on the PEEK surface by sandblasting, acid etching, plasma treatment, laser treatment, and adhesive systems. This paper provides a comprehensive overview of the research progress on the mechanical properties of PEEK for dental applications in the context of specific applications, composites, and their preparation processes. In addition, the research on the adhesive properties of PEEK over the past few years is highlighted. Thus, this review aims to build a conceptual and practical toolkit for the study of the mechanical and adhesive properties of PEEK materials. More importantly, it provides a rationale and a general new basis for the application of PEEK in the dental field.

“…By analyzing the number of macrophages, the differentiation and activation of myofibroblasts, and the density of collagen, it was proven that nano/Ta silicone rubber implants can reduce the formation of fibrous capsules and improve biocompatibility. Polyether ether ketone (PEEK) ( Wang et al, 2022 ) is known to have an elastic modulus similar to that of bone, but its bioinertia and osteogenic ability are poor. Lu et al used PIII to inject tantalum ion energy into PEEK and form Ta 2 O 5 nanoparticles on the surface ( Lu et al, 2015 ).…”

After bone defects reach a certain size, the body can no longer repair them. Tantalum, including its porous form, has attracted increasing attention due to good bioactivity, biocompatibility, and biomechanical properties. After a metal material is implanted into the body as a medical intervention, a series of interactions occurs between the material’s surface and the microenvironment. The interaction between cells and the surface of the implant mainly depends on the surface morphology and chemical composition of the implant’s surface. In this context, appropriate modification of the surface of tantalum can guide the biological behavior of cells, promote the potential of materials, and facilitate bone integration. Substantial progress has been made in tantalum surface modification technologies, especially nano-modification technology. This paper systematically reviews the progress in research on tantalum surface modification for the first time, including physicochemical properties, biological performance, and surface modification technologies of tantalum and porous tantalum.

“…These properties make PEEK an attractive material for application in extreme conditions and thus suitable as an insulation material in automotive and aerospace industries [ 1 ]. Furthermore, the properties also make PEEK promising for use in medicine, for example, as a material for dental implants [ 2 , 3 ]. As known for most polymers, the mechanical properties are further improved by enforcement with different fillers, often in the form of fibers.…”

Polyetheretherketone (PEEK) is the material of choice in several applications ranging from the automotive industry to medicine, but the surface properties are usually not adequate. A standard method for tailoring surface properties is the application of gaseous plasma. The surface finish depends enormously on the processing parameters. This article presents a review of strategies adapted for improved wettability and adhesion of PEEK. The kinetics of positively charged ions, neutral reactive plasma species, and vacuum ultraviolet radiation on the surface finish are analyzed, and synergies are stressed where appropriate. The reviewed articles are critically assessed regarding the plasma and surface kinetics, and the surface mechanisms are illustrated. The directions for obtaining optimal surface finish are provided together with the scientific explanation of the limitations of various approaches. Super-hydrophilic surface finish is achievable by treatment with a large dose of vacuum ultraviolet radiation in the presence of oxidizing gas. Bombardment with positively charged ions of kinetic energy between about 100 and 1000 eV also enable high wettability, but one should be aware of excessive heating when using the ions.
