“…In previous studies, in which the fracture type of PEEK material was evaluated after aging, it was reported that the material mostly showed flexural failure rather than fracture. 22,24,50 Consistently, surface distortions were observed on the PEEK surface without deep scratches in the present study. This different wear type may explain why the material has relatively quite low wear values, especially in depth and the high coefficient of variation.…”

“…Depending on the mechanical properties of the material in the PE group, there is more crush‐like wear than cracks on the surface. In previous studies, in which the fracture type of PEEK material was evaluated after aging, it was reported that the material mostly showed flexural failure rather than fracture 22,24,50 . Consistently, surface distortions were observed on the PEEK surface without deep scratches in the present study.…”

“…Ghodsi et al, 48 classified the fracture modes into favorable and unfavorable failures. A favorable failure occurs within the crown material while the abutment remains intact.…”

“…This is due to the fact that the use of composites in medicine solves many of the problems that affect metallic biomaterials including corrosion, susceptibility to microbial colonisation and human tissue-implant mechanical mismatch [ 3 , 4 , 5 ]. Polymer-ceramic composites (PCCs) have received particular attention due to their desirable physico-chemical properties such as abrasion resistance, the possibility of achieving a Young’s Modulus similar to that of human bones, aesthetic benefits, easy machinability and bioavailability [ 6 , 7 ]. PCCs are already used in restorative dentistry for repairing teeth with caries, while in dental prosthetics they are used for CAD/CAM milling blocks [ 8 , 9 ].…”
