Abstract:
The introduction of computer-aided design and computer-aided manufacturing in rehabilitation with removable partial denture, enabled the emergence of new methods of fabrication of the framework and materials. In view of this, polyether-ether-ketone appears as an alternative to Cobalt-Chromium, due to its aesthetic properties, high resistance and for being non-allergic. In this sense, the present study aimed to report a clinical case where the framework of a removable partial denture was manufactured from a digital workflow, using polyether-ether-ketone as the material of choice, compared to a

Thermal and wide-angle x-ray scattering (wAxs) studies of a new set of copolymers of polyether ether ketone (PEEK) with ether diphenyl ether ketone (EDEK) have been undertaken. The copolymerization modifies the properties of PEEK. At low levels of comonomer content the incorporation of the comonomer unit lowers the melting temperature and reduces the degree of crystallinity. At higher levels the melting point increases towards that of the PEDEK homopolymer. The x-ray structure is very similar to that of PEEK, consistent with rejection of the comonomer at low levels of comonomer content. At hig

Abstract:
Carbon fiber–reinforced polyether ether ketone (PEEK) is a strong candidate for aerospace bearing cages due to its low density and good mechanical properties. However, there are still concerns regarding its performance at the elevated temperatures seen in aerospace applications. In particular, an accurate measurement of PEEK's coefficient of thermal expansion (CTE) is critical to proper bearing design. In this paper, the CTE of as-manufactured PEEK cages was measured to determine the range of CTE that can be expected for production parts. A range of cage sizes and designs were considered in th

Abstract Dental implant can be defined as the process of inserting an artificial tooth in the place of the natural tooth. This artificial tooth consists of a) an abutment b) Custom made crown and (c) Implant. Dental implants are of two major types Endosteal and Subperiosteal Implant, endosteal is more widely used and nowadays Subperiosteal is very rare. Apart from types, it also has variety of materials usage. The widely used materials are titanium and zirconia. Both titanium and zirconium have lots of disadvantages, to overcome those we can use PEEK that is polyether-ether-ketone. PEEK has ma

Abstract:
Bearings are important in moving machinery. Today machines are used in varied fields, including environments where metals are not ideal materials. Industrial polymers are a possible alternative due to their mechanical properties, and the thermoplastic polymer Polyether ether ketone (PEEK) is suitable in many varied conditions. The failure mechanisms of PEEK are not fully understood, so the purpose of this study is to continue examining the relationship between load and rotation speed in rolling contact fatigue of PEEK thrust bearings in water conditions, to evaluate fatigue strength and life.

ABSTRACT Background: Polyether ether ketone (PEEK) has emerged as a new thermoplastic material with potential applications as a restorative material. Aim: This study aimed to evaluate the marginal adaptation of PEEK copings compared to zirconia copings using field emission scanning electron microscopy. Materials and Methods: A freshly extracted maxillary central incisor was prepared for a full-coverage restoration following standard principles of tooth preparation. The tooth was sent to a laboratory for fabrication of samples using computer-aided design and manufacturing (CAD/CAM). Twenty samp

Abstract:
The complex permittivity of films of polyether ether ketone (PEEK) has been investigatedover a wide range of frequency. There is no relaxation peak in the range of 1Hz to 10 5 Hz but in the low-frequency side (10 -4 Hz) there is an evidence of a peak that also can be observed by thermally stimulateddischarge current measurements. That peak is related with the glass transition temperature (T g ) of thepolymer. The activation energy of the relaxation was found to be 0.44 eV, similar to that of severalsynthetic polymers.

Polyether ether ketone (PEEK) is an important material which is used in several dental field like oral implantology, prosthodontic, orthodontic dentistry for dental implants, abutments, healing caps, orthodontic braces, and most importantly denture prosthetic framework. The best mechanical property of PEEK is that it overcomes the disadvantage of titanium implants i.e., aesthetic and allergic reaction. The aim of this article is to mainly focus on the surface modification of PEEK implant material to make it a better version of dental implant so that it overcomes the bioactivity and bone-integr

Abstract:
Shape-memory polymers (SMPs) have gradually emerged in the mechanism and biomedical fields and facilitate the upgrading of industrial mechanisms and the breakthrough of technical bottlenecks. However, most of the SMPs are infeasible in harsh environments, such as aerospace, due to the low glass transition temperature. There are still some works that remain in creating truly portable or non-contacting actuators that can match the performances and functions of traditional metal structures. Polyether-ether-ketone (PEEK) with a high glass transition temperature of 143 °C is endowed with outstandin

Abstract:
Polymers serve as important functional materials in various environments, including high-pressure conditions. However, the behavior of polymers under high pressure is currently less understood. In this study, the isothermal equation of state of polyether ether ketone (PEEK), an important polymer, was measured using the diamond anvil cell technique at up to 8 GPa. The isotropic compression behavior of PEEK samples was investigated by monitoring the area change in PEEK disks during the compression process using the optical imaging method.

This paper presents a theoretical analysis of the maximum contact stress and the lubrication regimes for PEEK (Polyether-ether-ketone) based self-mating cervical total disc arthroplasty. The NuNec® cervical disc arthroplasty system was chosen as the study object, which was then analytically modelled as a ball on socket joint. A non-adhesion Hertzian contact model and elastohydrodynamic lubrication theory were used to predict the maximum contact stress and the minimum film thickness, respectively. The peak contact stress and the minimum film thickness between the bearing surfaces were then dete
