AIMS The determination of the volumetric polyethylene wear on explanted material requires complicated equipment, which is not available in many research institutions. Our aim in this study was to present and validate a method that only requires a set of polyetheretherketone balls and a laboratory balance to determine wear. METHODS The insert to be measured was placed on a balance, and a ball ...

The well-known Taylor cylinder impact test, which follows the impact of a flat-ended cylindrical rod onto a rigid stationary anvil, is conducted over a range of impact speeds for two polymers, polytetrafluoroethylene (PTFE) and polyetheretherketone (PEEK). In previous work, experiments and a model were developed to capture the deformation behaviour of the cylinder after impact. These works show...

OBJECTIVE To evaluate the properties of a combination bone graft consisting of biphasic calcium phosphate ceramic, polyetheretherketone (PEEK) cage in one- and two-level surgery. METHODS Over a 12-month time period, a prospective single surgeon series of 75 patients were included in the study and 58 patients selected based on adequate data points. From these 58 patients, 32 were supplemented ...

Abstract Polyetheretherketone (PEEK) is a semi‐crystalline thermoplastic polymer that has been gradually used in the repair of bone defects because its well chemical stability, reliable biocompatibility, excellent X‐ray radiolucency, and low modulus. However, PEEK biologically inert material, planktonic bacteria can adhere to surface eventually form biofilms, allowing for rapid development impl...

The combined effect of the use of carbon fiber and seawater and the molecular structure on the tribological behavior of various polymer materials under natural seawater lubrication was investigated. After the investigation, the wear morphology of the contact surface was observed by a laser scanning confocal microscope, and the texture of the wear scars and tracks were presented in 3D profiles. ...

Introduction: Clasp is an important component in a removable partial denture. Conventional clasps are usually made of metal alloys. The patient refuses to have clasp due the unaesthetic color that affects their appearance. This article aims determine types other than those Overview: Polyetheretherketone (PEEK) ketone-based crystalline thermoplastic resin commonly used dentistry for crowns, impl...
