Abstract

Aim:The aim of this study is to investigate the effect of different firing program preferences on the connection between zirconium oxide and veneer ceramics both during sintering of zirconium oxide based substructure blocks and during the firing of veneer ceramics to be applied on the substructure, especially considering the cooling rates.Materials and Methods:144 Y-TZPsubstructures (7 mm. * 3 mm.) were produced. These samples were then divided into 2 main groups (group P1-n = 72 and group P5-n = 72) according to cooling procedures after sintering. These two main groups are divided into 4 subgroups as slow cooling and fast cooling determined by the manufacturer of two different brands of porcelain. All of the samples were subjected to 5000 cycles of thermal cycling. Each sample was tested with a Universal tester of 0.5 mm./min. shear bond strength test at head speed. Blade tip for cutting, 1 mm. thick and blunt. The angle between the test blade and the specimens was 90º and the speed was 1 mm / minute. Mann Whitney U test was used for statistical analysis and the results were evaluated according to p

Özet

Amaç:Çalışmamızın amacı, hem zirkonyum oksit esaslı alt yapı blokların sinterlenmesi, hem de alt yapı üzerine uygulanacak olanveneer seramiklerin fırınlanması esnasında, özellikle soğuma hızları dikkate alındığında, farklı fırınlama program tercihlerinin, zirkonyum oksit ve veneer seramik arasındaki bağlantıya etkisini araştırmaktır.Gereç ve Yöntem:144 adet Y-TZP alt yapı (7 mm.* 3mm.) olacak şekilde üretilmiştir. Daha sonra bu örnekler sinterleme işleminden sonraki soğutulma prosedürlerine göre 2 ana gruba ayrılmıştır (grup P1-n=72 ve grup P5-n=72). Bu iki ana grup ise iki farklı marka porselenin üretici firma tavsiyeli yavaş soğutma ve bizim belirlediğimiz hızlı soğutma olmak üzere 4 er adet alt gruplara ayrılmıştır. Üretilen örneklerin hepsine 5000 devir termal siklus uygulanmıştır. Her bir örnek Universal test cihazında 0,5mm/dak. kafa hızında makaslama bağlanma dayanımı testine tabi tutulmuştur. Kesme işlemini yapacak bıçak ucu, 1 mm. kalınlığında ve künt olacak şekilde hazırlanmıştır. Test bıçak ucu ile örnekler arasındaki açı 90º, hızı ise 1 mm/dakika olarak gerçekleştirilmiştir. İstatistiksel analizler Mann Whitney U testi kullanılarak sonuçları p
