Abstract (2. Language): 
In this investigation bond strength of Molloplast-B resilient liner to various acrylic resin denture base materials was evaluated by using a tensile bond strength procedure. Lucitone 199, Pacton and Meliodent acrylic resin surfaces were processed as uncured and smooth versus precured and roughened before bonding with Molloplast-B. Ivocap and Compresin resins were measured using an Universal Instron testing machine at a constant deformation rate oj 2mmlmin. Lucitone showed the lowest mean bond strength value (7.61 kg/cm2), Meliodent exhibited the highest mean bond strength value (12.91 kg/cm2). It was concluded fom this study that sufficient bond strength can be achieved with use of unconventional acrylic resins with resilient liners and roughening thepre-cured acrylic resin surfaces increase the bond strength for certain resins.

Abstract (Original Language): 
Bu araştırmada yumuşak astar maddesi Moİloplast-B'nin akrilik protez kaide materyallerine bağlanma dayanımı çekme deneyi metodu ile incelenmiştir. Deney örnekieri hazırlanırken Moİloplast-B'nin bağlandığı Lucitone 199, Pacton ve Meliodent akrilik reçine yüzeyleri polimerize edilmemiş halde ve ayrıca polimerize pürüzlü yüzeyler halinde hazırlanmıştır. Ivocap ve Compressin'in yüzeyleri ise polimerize edilerek pürüzİendirilmişlerdir. Bağlanma dayanım Ölçümleri Universal Instron test cihazında, sabit bir deformasyon hızıyla gerçekleştirilmiştir. En az bağlanma dayanımını ise 7.61 kg/cm2 ile Meliodent göstermiştir. Sonuç olarak Molloplast-'nin genellikle birlikte kullanıldığı kırılma dayanımı yüksek olan akrilikler dışında diğer tür akriliklerle de yeterli bağlanma sağlayabileceği ve bazı polimerize edilmiş akriliklerin pürüzlendirilmesinin bağlanmayı güçlendirdiği anlaşılmıştır.
