Abstract

The aim of this in vitro study was to comparethe marginal fit of 3 different heat-pressed allceramic crown systems Creapress, IPS Empressand Finesse both staining and layering techniquesand porcelain-fused-to-metal restorations PFM utilizing with the silicone replica technique and animage analysis system.A total of 70 crowns were prepared for 7groups n=10 on metal dies, representing the maxillary right central incisor. Measurements of marginal fit were performed at 2 points for each crownusing the silicone replica technique and an imageanalysis system. One-way analysis of variance andpaired t test were used to compare data a=0.05 . The average marginal opening of the testedgroups ranged from 32.4 ± 13.3 to 52.6 ± 14.8 µm.Analysis revealed that there were no significant differences in the mean marginal opening among thegroups p > 0.05 . The marginal fits of crowns arenot influenced by different heat-pressed all-ceramic systems. The marginal openings of all testedgroups were less than the clinically acceptable limitof 120µm. As a result of this study, all heat-pressed allceramic crown systems are reliable regarding themarginal opening

ISI İLE PRESLENEN FARKLI TAM SERAMİK KRONLARIN MARJİNAL UYUMLARININ İN VİTRO OLARAK DEĞERLENDİRİLMESİ

Abstract

Bu çalışmanın amacı ısı ile preslenen 3 farklıtam seramik kron sisteminin Creapress, IPSEmpress ve Finesse; boyama ve tabakalamatekniği ve metal destekli porselen restorasyonlarınmarjinal uyumlarını silikon kopyalama tekniği vegörüntü analiz sistemi yardımıyla karşılaştırmaktır. Toplam 70 örnek, üst santral dişi yansıtanmetal daylar üzerine 7 gurupta n=10 hazırlandı.Marjinal uyum silikon kopyalama tekniği ve görüntü analizleme yöntemiyle her bir kronda 2 noktadanölçüm yapılarak değerlendirildi. Veriler tek-yönlüvaryans analizi ve eş yapma t testi ile karşılaştırıldı a=0.05 . Grupların marjinal açıklık ortalamalarının32.4 ± 13.3 ile 52.6 ± 14.8 µm arasında değiştiğibulundu. Gruplar arasında istatistiksel olarak marjinal açıklık açısından fark bulunamadı p > 0.05 .Çalışma sonuçlarımıza göre, tam seramik kronlarınmarjinal uyumları farklı ısı ile şekillendirmetekniklerinde farklılık göstermedi. Test edilen tümkronların marjinal açıklığı klinik olarak kabuledilebilir 120µm seviyesinin altında tespit edildi.Sonuç olarak, araştırmada kullanılan ısı ilepreslenen tam seramik kron sistemlerinin marjinaluyum açısından güvenilir olduğu bulunmuştur
