Abstract

Objective: Although polyether ether ketone (PEEK) shows high biocompatibility in prosthetic dentistry, there is inadequate information about its clinical applications and limits. The purpose of this study was to compare the load-bearing capacities of PEEK, hybrid ceramic and zirconia crowns, which were fabricated using computeraided design and computer-aided manufacturing (CAD/CAM). Materials and Methods: Three groups (n=10) of high-resistance PEEK polymer, hybrid ceramic and zirconia were fabricated using CAD/CAM. A universal test machine was used to assume the fracture resistance of all specimens. The specimens were loaded until final fracture occurred and load at fracture was recorded. Fracture resistance data were statistically analyzed by Tukey honest significant difference multiple comparison test. Results: There was no significant statistical difference between PEEK group (2214±236 N) and hybrid ceramic group (2325±264 N) in relation to the loadbearing capacities (p>0.05), while zirconia group (3292±192 N) showed the highest values for fracture load. Conclusion: All three crown materials were successful against physiological occlusal forces. Regarding the limitations of this in vitro study, PEEK could be an alternative crown material for fixed dental prostheses.

Özet

Amaç: Polieter eter ketonun (PEEK) protetik diş hekimliğinde göstermiş olduğu yüksek biyouyumluluğuna karşın, klinik uygulamaları ve sınırları hakkında yeterli bilgi bulunmamaktadır. Bu çalışmanın amacı, bilgisayar destekli tasarım ve bilgisayar destekli üretim (CAD/CAM) kullanılarak üretilen PEEK, hibrit seramik ve zirkonyum kronlarının basma dayanım kapasitelerini karşılaştırmaktır.Gereç ve Yöntemler: Yüksek dirençli PEEK polimer, hibrit seramik ve zirkonyum olmak üzere üç grup (n=10) CAD/CAM kullanılarak üretildi. Tüm örneklerin kırılma direncinin değerlendirilmesi için üniversal test makinesi kullanıldı. Örneklere kırılma meydana gelene kadar yükleme yapıldı ve kırılma anındaki yük değerleri kaydedildi. Kırılma direnci verileri Tukey-honest significant difference çoklu karşılaştırma testi ile istatistiksel olarak analiz edildi.Bulgular: Basma dayanım kapasitelerine göre PEEK grubu (2214±236 N) ile hibrit seramik grup (2325±264 N) arasında istatistiksel olarak anlamlı fark gözlenmezken (p>0,05), zirkonyum grubu (3292±192 N) kırılma dayanımında en yüksek değerleri gösterdi.Sonuç: Her üç kron materyali de fizyolojik okluzal kuvvete karşı başarılıydı. Bu in vitro çalışmaların sınırları doğrultusunda, PEEK materyali sabit protezler için alternatif bir kron materyali olabilir.
