Abstract (2. Language): 
The aim of our study was to compare the in vitro tensile strength and shear strength, of crowns prepared with indirect method in dental laboratory for the restoration ol _ I »«.I k n.-ıricın-j* M. hlı-h i o sı hvhiTil composite resin, and Definite OMC, which is an ormocer, were used in order to prepare the crowns. Tensile strength and shear strength of the crowns prepared were determined by using Hounsficld testing machine. As a result of the tensile strength test, it was found that Charisma Indirect Crowns group has lower strength than Delimle Indirect Crowns group , but th^re was no statistically differences among the groups (P>0,05), As a result of the shear strength test, it was found that. Charisma Indirect Crowns group was stronger than Definite Indirect Crowns group. However, the differences among the groups were not. significant statistically These crowns easily prepared in laboratory facilities may be preferred in the restorations of primary anterior teeth, while the bitting fortes of children are considcred.too.
Abstract (Original Language): 
Çalışmamızın amacı, silt ön dişlerin restorasyonunda kullanılmak üzere laboratuvar ortamında indirekt yöntemle 1.., ..^1.-. l'i.PAvıl.ınr İTI ıritr-f,, jılnr.jlt ,-jıl-Ti-ip- ı-r- hacı iv M V:-IT-.I ııtu.ıı ııııım. nuı ujııuıııı ııı 'mu S""-1 ' V- dirençlcrini karşılaştırmaktır. Kuronların hazırlanmasında, bir hibrid kompozit reçine olan Charisma ve bir ormoser olan Definite OMC materyalleri kullanılmıştır. Hazırlanan kurumların, çekme ve basınca kargı dirençleri Houusl'idd tensometresi kullanılarak belirlenmiştir. Çekme testi sonucunda Definite İndirekt Kuron grubu Charisma İndirekt Kuron grubundan daha zayıf bulunmuştur. Takat gruplar anısında istatistiksel olarak farklılık gözlenmemiştir (P>0,05)- Basınç testi sort ucunda ise, Charisma İndirekt Kuron grubu Definite İndirekt Kuron grubundan daha güçlü bulunmuştur. Bununla birlikLe. aralarındaki farklılık istatistiksel olarak önemsizdir (IV0.05). Laboratuvar ortamında kolaylıkla hazırlanabildi bu kuronlar, çocukların ısırma kuvvetleri dc göz önüne alındığında süt ön diş restorasyonlarında tercih edilebilirler.
