Results: The fracture strength results of the DC-Tell samples with thermo-cycling showed the lowest values (753,60 N) and the metal samples showed the highest values (2282,20 N). (p = 0.001) Conclusion: While constructing cores under crowns with CAD/ CAM fabricated zirconium-oxide copings, good mechanical properties and clinical successes can be achieved with metallic materials.

Abstract

Background and Aim: High strength ceramics fabricated with CAD/ CAM technology have widely extended the applications of all ceramic restorations from inlay, onlay and single crowns to multi-unit bridges, showing more favorable mechanical characteristics compared to the conventional metal ceramic materials. The aim of this in-vitro study was to investigate the fracture strengths of high strength CAD/ CAM fabricated zirconium oxide copings with two different core structure materials in the molar area. Materials and Methods: Ten metal and twenty DC-Tell dies produced by the means of Lava® procedure for the mandibular I. molar were manufactured. Partially stabilized zirconia blanks (DC-Zircon) have been used to prepare the ceramic copings. Thermo-cycling was for done to ten metal and ten DC-Tell die specimens. All the samples were then tested for their fracture characteristics with a universal testing machine (Zwick-010, Ulm, Germany). Results: The fracture strength results of the DC-Tell samples with thermo-cycling showed the lowest values (753,60 N) and the metal samples showed the highest values (2282,20 N). (p = 0.001) Conclusion: While constructing cores under crowns with CAD/ CAM fabricated zirconium-oxide copings, good mechanical properties and clinical successes can be achieved with metallic materials.

Özet

Amaç: CAD/CAM teknolojisi ile üretilen yüksek dayanıklılığa sahip seramikler, geleneksel metal-seramik materyallere göre daha olumlu mekanik özellik sergilediklerinden, tam seramiklerin uygulama alanları, inley, onley ve tek kronlardan, çoklu-üyeli köprülere genişlemiştir. Bu in-vitro çalışmanın amacı, molar bölgede, iki farklı kor materyali için hazırlanan, CAD/CAM ile üretilen yüksek dayanıklılığa sahip zirkonyum-oksit kopinglerin kırılma dayanıklılıklarının araştırılmasıdır. Gereç ve Yöntem: Lava® yöntemi ile alt 1. azı diş için 10 adet metal ve 20 adet DC-Tell day üretildi. Seramik kopinglerin hazırlanması için kısmi-stabilize zirkonyum bloklar (DC-Zircon) kullanıldı. On metal ve on DC-Tell daya termal siklus uygulandı. Daha sonra tüm örnekler, kırılma karakteristiklerin tespiti için evrensel test cihazında (Zwick-010, Ulm, Almanya) test edildi. Bulgular: Termal-siklus uygulanmış DC-Tell örneklerin kırılma dayanıklılık değerleri en düşük bulunurken (753,60 N), en yüksek değeri metal örnek grubu gösterdi (2282,20 N). (p = 0.001) Sonuçlar: CAD/ CAM ile üretilen zirkonyum oksit alt yapılı kronlara kor hazırlanırken, metalik materyaller ile daha iyi mekanik özellik ve klinik başarı elde edilebilir.
