The aim of the present study was to compare the load bearing capacity of monolithic or bilayered single crowns with zirconia or polyetherketoneketone frameworks designed and fabricated using CAD/CAM systems.Cr-Co-based metal dies (n = 60) were duplicated from an extracted and prepared premolar and then restored with different CAD/CAM materials.

Carbon-fiber-reinforced thermoplastic (CFRTP) materials have drawn considerable interest owing to their high strength-to-weight ratio. Laser joining technologies have been reported to join CFRTP to metals or plastic ma-terials. However, the direct laser joining of CFRTP/CFRTP is challenging.

New adhesive protocol improves shear bond strength of Polyetherketoneketone (PEKK)
Dental MaterialsInert surface of Polyetherketoneketone (PEKK) jeopardizes resin bonding. This study aimed to present a new adhesive protocol to improve PEKK bonding.A total of 360 PEKK blocks were milled, polished (maximum roughness of 0.20 µm), and randomly assigned to groups. The new protocol was applied (n = 36) and compared to conventional treatments (no treatment;

ABSTRACTWhile polyetherketoneketone is a high‐performance thermoplastic polymer, its hydrophobicity and inertness limit bone adhesion. This study aimed to evaluate a novel PEKK/CaSiO3/TeO2 nanocomposite, comparing it to PEKK/15 wt.% CaSiO3 and PEKK groups. The in vitro study, involving 90 discs (n = 30), assessed the cytotoxicity of all groups after 24,

Polyetherketoneketone, a high-performance polymer for splinting mobile teeth: A clinical report
The Journal of Prosthetic DentistryA digital workflow for fabricating a polyetherketoneketone (PEKK) periodontal splint is described. The antibacterial properties of PEKK and the precision and efficiency of digital technology led to the provision of a splint with no adverse effects on oral hygiene or periodontal maintenance during a 2-year follow-up.
