Abstract

Purpose: To compare the effect of autoclave and microwave post-polymerization treatments on flexural strength of hard reline and heat-polymerized acrylic resins. Material and Methods: Hard chairside reline and heat-polymerized acrylic resin specimens (64x10x3.3 mm) were fabricated. 80 specimens with 4 subgroups for each acrylic (n=20) received post-polymerization treatment by microwave irradiation and two autoclave post-polymerization mo- dalities (short and long). Specimens were subjected to flexural strength testing using 3-point bending with a crosshead speed of 5 mm/min. Two-way, one-way ANOVA and Tukey s HSD tests were used for statistical analysis of data. Results: The microwave post-polymerization significantly increased the strength of heat polymerized acrylic resin and hard chairside reline resin specimens where its effect was significantly higher than the autoclave and control groups (p

Özet

Amaç: Otoklav ve mikrodalga post-polimerizasyon uygulamalarının sert besleme akriliği ve ısı ile polimerize olan akriliğin bükülme direnci üzerine etkisinin karşılaştırılması. Gereç ve Yöntem: Sert besleme akriliği ve ısı ile polimerize olan akrilik malzemeden 64x10x3.3 mm boyutunda örnekler hazırlandı. Her iki akrilikten 80 adet örnek hazırlandı ve 4 alt gruba ayrıldı (n=20). Örnekler, mikrodalga ve otoklavda (kısa ve uzun programda) kullanılarak otoklav post-polimerizasyonuna tabi tutuldu ve 5 mm/dak hızla 3 nokta bükülme testi uygulandı. İstatistiksel analiz için iki yönlü ve tek yönlü ANOVA ve Tukeys HSD testleri kullanıldı. Bulgular: Mikrodalga ile post-polimerizasyon, her iki akriliğin bükülme direncini anlamlı olarak arttırmıştır (p
