Abstract

Amaç: Bu çalışmanın amacı farklı sistem ve zirkonya materyalleri kullanılarak üretilen kuron alt
yapılarını kenar uyumu açısından karşılaştırmaktır.
Gereç ve Yöntem: Akrilik üst küçük azı diş modeli üzerinde basamaklı diş preparasyonu yapıldı.
Hazırlanan preparasyon üzerine beş farklı sistem-zirkonya esaslı blok (Cerec-InCoris ZI, Everest-BioZH,
Celay-In-Ceram Zirconia, Zirkonzahn-IceZirkon ve Lava-Frame Zirconia) kullanılarak alt yapılar üretildi
(n=10). Kontrol grubu olarak kıymetsiz metal alaşımından (Ni-Cr) elde edilen metal alt yapılar kullanıldı.
Alt yapıların kenar açıklık değerleri stereomikroskop yardımıyla ölçüldü. Elde edilen verilerin istatistiksel
analizi Tek-yönlü varyans analizi ve Bonferroni testi yardımıyla p < 0.05 düzeyinde değerlendirildi.
Bulgular: Kenar açıklığı değerleri en düşükten yükseğe göre Lava

Keywords
