Fracture Resistance of Zirconia, Polyetheretherketone, and Polyetherketoneketone Implant Abutments After Aging [PDF]

The International Journal of Oral & Maxillofacial Implants, 2021
This study aimed to assess the fracture resistance of zirconia (Zr), reinforced polyetheretherketone (PEEK), and polyetherketoneketone (PEKK) implant abutments restored with glass-ceramic crowns after thermomechanical aging.Zr, reinforced PEEK, and PEKK titanium base abutments were divided into three groups (n = 10).

Thermal conductivity and diffusivity of carbon‐reinforced polyetherketoneketone composites [PDF]

Journal of Applied Polymer Science, 2019
ABSTRACTHeat transfer properties play an important role in processing of polyetherketoneketone (PEKK)/carbon fiber (CF) composites. Accordingly, thermal conductivity and diffusivity of PEKK, PEKK/glassy carbon (GC), and PEKK/CF composites have been studied. Observed increase in conductivity and diffusivity with carbon filler addition was analyzed using

Shear bond strength of adhesive systems on PEEK, PEKK, and fiber-reinforced composites: an in vitro study [PDF]

BMC Oral Health
Background Strong and durable bonding between composite resins and high-performance polymers (HPPs) is difficult to achieve because of HPPs’ low surface energy and chemical inertness, which limit their clinical applicability. This in vitro study aimed to

Effect of polydopamine coating on adhesion of resin composite to polyetherketoneketone (PEKK) [PDF]

International Journal of Adhesion and Adhesives, 2023
Statement of problem: Polydopamine (PD) adsorbs on all kinds of surfaces by forming strong covalent bonds, and develops cohesive strength through self-polymerization, resulting on thin strong adhesive films. Thus, PD coating could be promising to improve
