Farklı Yumuşak Ve Sert Astar Materyallerinin Protez Kaidesiyle Olan Bağlantısının Ve Sertliklerinin İncelenmesi

GİRİŞ ve AMAÇ: Dokuz farklı yumuşak ve sert astar materyalinin protez kaidesiyle olan çekme bağ dayanımlarının (ÇBD) ve zamana bağlı sertlik değerlerinin incelenmesidir. YÖNTEM ve GEREÇLER: Mollosil Plus, Ufi Gel SC, Molloplast-B, Visco-gel ve GC Tissue Conditioner yumuşak astar materyallerinden, Ufi Gel hard C, GC Reline Hard, Vertex Self Curing, Vertex Rapid Simplified sert astar materyallerinden çekme bağ dayanımı testi için 144 adet örnek hazırlandı. Örnekler termal siklus ve kontrol grubu olamak üzere iki ana gruba ayrıldı. ÇBD testi universal test cihazında gerçekleştirildi. Sertlik testi için toplamda 90 örnek hazırlandı. Farklı zaman periyodlarındaki yumuşak astarların sertlikleri Shore A Durometre, sert astar materyallerinin sertlikleri ise Vicker's Sertlik test cihazı ile ölçüldü. İstatistiksel analizler için tek yönlü ANOVA ve Bonferroni testi kullanıldı (p

Evaluation Of Tensile Bond Strength And Hardness Of Different Soft And Hard Lining Materials To A Denture Base

INTRODUCTION: To investigate the bonding properties of 9 different soft and hard-lining-materials to a denture base resin by tensile-bond-strength (TBS) test and evaluate their hardness changes in time. METHODS: Mollosil Plus, Ufi Gel SC, Molloplast-B, Visco-gel and GC Tissue Conditioner soft-liningmaterials and Ufi Gel hard C, GC Reline Hard, Vertex Self Curing, Vertex Rapid Simplified hard-liningmaterials were used to prepare 144 samples for the TBS test. Samples were divided into two main groups of thermocycled and control samples. TBS test was performed with a Universal Test Machine. For the hardness test 90 samples were prepared. Soft-liners’ hardness were measured by Shore A Durometer and hard-liners were measured by Vicker's Hardness tester at different time periods. One-way ANOVA and Bonferroni tests were used for statistical analyses (p
