Abstract The aim of this study was to evaluate the fracture strength of poly ether ether ketone abutment over short implant after fatigue using chewing simulator device to introduce fatigue to abutments and universal test machine for fracture resistance assessment. Forty implants, divided into two main groups implants group (n=20) group (GI) group contain 20 short implants, (GII) contain 20 standard implants. Each group subdivided into two sub groups GIA contains 10 PEEK abutments over short implants, GIB contain 10 titanium abutments over short implants, and GIIA contain 10 PEEK abutments over standard implants. |
