dc.description.abstractThe aim of this study was to compare the fracture strength of peek abutments and zirconium abutments which are widely preferred instead of titanium abutments in the esthetic zone for the implant supported fixed prosthesis. In this study, the fracture strength of zirconium and peek abutments were compared after aging by chewing simulator. Study groups were; Group 1: 10 zirconium abutments on the implants (Bredent, Germany, 12 mm length and 4 mm diameter) , Group 2: Peek abutments on the implants (Bredent, Germany, 12 mm length and 4 mm diameter). All implants are embeded into an acrylic resin (Paladent-Kulzer) with 45° angle and torqued with 25 N to the implants. Afterwards, zirconia cores (Zenostar T2 Wieland) were cemented with temporary implant cement (Premier; ABD). Fatique test was performed with a chewing simulator for 1,2 million cycles. Subsequently, load to fracture test was applied by a loading device (Shimadzu, Japan) to all specimens with a speed of 1mm/ min. The fracture strength values were 478,83± 66,72 N for peek abutment group and 722,50± 84,71 N for zirconium abutment group. The results were statistically analysed with T-test. The fracture strength of zirconia abutments were statistically significantly higher than peek abutments (p< 0,001). Key words: Zirconia, ceramic, peek, abutment, fracture strengthen
