FARKLI SİSTEM VE MATERYALLERLE ÜRETİLEN ZİRKONYA ALT YAPILARIN KENAR UYUMLARININ KARŞILAŞTIRILMASI

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

Purpose: The aim of this study was to compare marginal fit of zirconia copings produced by different systems and materials.Material and Methods: Tooth preparation with circumferential shoulder was performed on maxillary premolar acrylic tooth model. Copings (n=10) were produced with 5 different system-zirconia blocks (Cerec-InCoris ZI, Everest-BioZH, Celay-In-Ceram Zirconia, Zirkonzahn-IceZirkon ve Lava-Frame Zirconia) on prepared tooth model. Metal copings (Ni-Cr) were used as a control group. Marginal discrepancy of copings were measued with a stereomicroscope. Statistical analysis was performed with One-way ANOVA and Bonferonni test (p
