Abstract (2. Language): 
The technique of bonding eetrolytically etched cast base metals to composit resins, and acrylic resins creates a microretentive surface which is rarely used. In our study thirty metal specimens from Cr-Ni base metal alloy (5* 10 mm width and 1mm in thickness) (Wiralloy® Bcgo, Germany) were prepared by a lost was technique. The first fifteen alloy specimens were sand blasted and clcctrolytically etched. The remaining fifteen alloy specimens were just sandblasted and used as controls. The conventional porcelain (2*3 mm. width and 2mm height) was applied and lired on the metal surfaces. Shear lest was applied to the test samples and the force; when the failure ocetircd was recorded. Anova test was performed on the data. According to our results there was a statistically significant difference between the bond strengths (p<0.01).

Baz melal alaşımlarının komptw.it rezinlcr ve akrilik rezinlcr ile bağlantı kuvvetim, metal yüzeyinde mikro tutuculu yüzeyler oluşturul ması ilkesiyle uygulanan elektrolitik purii/.lendirmc bilinen takat özellikle metal porselen uygu lamalarında az kullanılan bir yöntemdir. Çalışmamı/.da krom-nikeİ baz metal alaşımından (WiroHoy® Hego , Germany) 30 adet lmm. kalınlığında vç 5X.10mm"ebatlarında örnek döküm yöntemi ile oluşturuldu. Bu çimeklerden ilk 15' ine sadece kumlama diger 15' ine ise elektrolitik pürüzlcndirme işlemi uygulandı. Metaller üzerine 2mm. yükseklik ve 2x3ram ebatlarında porselen konvansiyon el tekniklerle pişirildi. Metal-porselen bağlantı bölgesine Universal test cihazında shear test uygulandı. Kopma anındaki değerler kaydedildi. Sonuçlar anova ile istatistiksel olarak değerlendirildi. Sonuçlarımıza göre bağlanma değerleri arasındaki farklar istatistiksel olarak anlamlı idı(rx0.01).
