What is PEKK?
Which material properties are named?
PEKK is described with physical, mechanical, and biological properties. The mechanical properties named include compressive, tensile, and flexure strength.
[2]Where can PEKK be used?
PEKK is discussed for fixed and removable prostheses, oral implants, and clasps in removable prostheses. It is also considered as an alternative to titanium in implant applications.
[2]Which materials can it be compared with?
PEKK and PEEK are PAEK materials. The review also places high-performance polymers alongside ceramic and metal as restoration-material alternatives.
[2]What does PEKK change for a clasp or implant?
PEKK clasps can be used in removable prostheses as an alternative to nylon inserts because they are more retentive. When combined with titanium, PEKK is reported to provide long-lasting retention.
[2]What limits should be kept in view?
The review describes the dental literature on PEEK and PEKK as limited. Polymer frameworks are also reported to have high thermal expansion, faster degradation than metal, and possible chemical-leaching concerns.
[2]Frequently asked questions
Can PEKK be used for a removable-denture clasp?
PEKK clasps are discussed for removable prostheses and are reported to be more retentive than nylon inserts.
