Artan estetik beklentiler sonucunda sabit protetik tedavi yapımında tam seramik restorasyonlar kullanılmaktadır. Zirkonyum oksit ile güçlendirilmiş seramikler gelişmiş estetik ve mekanik özelliklere, biyouyumluluğa, düşük plak birikimine ve düşük termal iletkenliğe sahiptirler. Zirkonya altyapılı restorasyonların geleneksel metal altyapılı restorasyonlara alternatif bir tedavi olduğu düşünülmektedir. Ancak yapısındaki yüksek kristalin faz nedeniyle opak bir yapıya sahip olduğu bilinmektedir. Estetik gereksinimler zirkonyanın monolitik kullanımını sınırlandırarak, optimum renk ve translüsensiye sahip bir veneer seramiği ile kaplanmasını gerektirmektedir. Zirkonya alt yapı ve veneer seramiği arasındaki bağlantı altyapıya uygulanan yüzey işlemleri, veneer seramiğine uygulanma yöntemi ve mekanik özellikleri gibi faktörlerden etkilenmektedir. Bağlantıyı etkileyen faktörler bilinmesine rağmen bağlantı mekanizması bilinmemektedir. Bu derleme zirkonya ve veneer seramikler arasındaki bağlantı mekanizmasını ve etkileyen faktörler ile ilgili genel bilgi veren bir literatür taramasıdır.
As a result of increased aesthetic expectations, complete ceramic restorations are used in the production of fixed prothetic therapy. Ceramics reinforced by zirkonium oxide have advanced aesthetic and mechanical properties, biolocation, low plaque accumulation and low thermal conductivity. Zirconium infrastructure restorations are considered to be an alternative treatment to traditional metal infrastructure restorations. However, it is known that the high crystal in its structure has an unclean structure due to the phase. Aesthetic requirements require the monolithic use of zirconium to be covered with a veneer ceramics with optimal color and translucensity. The connection between the Zirconium substructure and the veneer ceramics is affected by factors such as the surface processes applied to the infrastructure, the method of application to the veneer ceramics and its mechanical characteristics. Although the factors affecting the connection are known, the connection mechanism is unknown. This collection is a literary scan that provides general information on the connection mechanism between the zirconium and veneer ceramics and the influential factors.
All-ceramic restorations are preferred in fixed prosthodontics treatments as a result of increasing esthetic expectations. Zirconium-oxide based ceramics offer advanced esthetic and mechanical features, bio-compatibility, decreased plaque accumulation and low thermal conductivity. Zirconia-based restorations are considered to be an alternative treatment method to conventional metal ceramic restorations. However it is known that zirconia based ceramic has increased opacity due to its high crystalline content. Esthetic expectations limited the monolitic usage of zirconia and require veneering with a ceramic which has optimal colour and transluceny. The bond strength between zirconia and veneering ceramic is affected by the factors like surface treatments applied on zirconia cores, the mechanical properties of veneer ceramics and the application methods of ceramics. But the bonding mechanism between zirconia and veneering ceramic is still unknown. This article offers a review of the literature about the factors affecting the bond strength between zirconia cores and veneer ceramics ceramics and their bonding mechanism.
