Abstract:

 OBJECTIVE: To explore the stress distribution on the bone-implant structures caused by the Polyetheretherketone PEEK, Polyetherketoneketone PEKK, and titanium fixtureabutments by using the three-dimensional 3D finite element analysis FEA. MATERIALS AND METHODS: Six models composed of titanium, PEEK, and PEKK implantabutments under vertical 250 N and 45 oblique 100 N loading were studied. The obtained principal and von Mises stress values from the models were evaluated. RESULTS: von Mises stresses were found to be highest in titanium implants and abutments under vertical and oblique loads. Extremely increased stress values were observed in the screws of the Polyaryletherketone PAEK models compared to titanium models. Lower principal stresses were observed in titanium models than PAEK models in the cancellous and cortical bone under vertical and oblique loads. CONCLUSION: PAEKs transmitted more stress to the peri-implant bone. Stress distribution in titanium models were more homogenous while stress concentrated in the bone adjacent to the coronal part of the implants and neck of the implants in PAEKs.

 AMAÇ: Bu çalışmanın amacı, üç boyutlu 3D sonlu elemanlar analizi SEA kullanarak Polietereterekketon PEEK, Polieterketonketon PEKK ve titanyum implantdayanakların kemik-implant yapılarında neden olduğu stres dağılımını araştırmak. GEREÇ VE YÖNTEM: Dikey 250 N ve 45 oblik 100 N yükleme altında titanyum, PEEK ve PEKK implantdayanaklardan oluşan altı model üzerinde çalışıldı. Modellerden elde edilen principal ve von Mises stres değerleri değerlendirildi. BULGULAR: von Mises gerilme değerlerinin dikey ve oblik yükler altında titanyum implantlarda ve dayanaklarda en yüksek olduğu bulundu. Poliarileterketon PAEK modellerin vidalarında titanyum modellere göre son derece yüksek stres değerleri gözlendi. Dikey ve oblik yükler altında spongioz ve kortikal kemikte titanyum modellerde PAEK modellerine göre daha düşük principal gerilim değerleri gözlendi. SONUÇ: PAEKler implant çevresindeki kemiğe daha fazla stres aktardı. Titanyum modellerde stres dağılımı daha homojen iken PAEKlerde stres implantların koronal kısmına komşu kemikte ve implant boynunda yoğunlaşmıştır.
