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

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).
