Interventions

Polyetherketoneketone (PEKK) forms a group of high-performance thermoplastic polymers. PEKK shows excellent biocompatibility and exhibits outstanding properties such as high wear resistance and high compressive (246 MPa), flexural (5.0GPa), and tensile strengths (115 MPa). The material is lightweight, allows shock absorption, and can be veneered with various commercially available dental materials
