Abstract

Aim: The purpose of study is to assess the tensile strengthbetween porcelain teeth and two different denture base (polyamide and heat-polymerized acrylic), a repair material (auto-polymerizing acrylic) after different types of surface treatment.Materials and Methods: Total of 63 same form and colormandibular right first molar porcelain denture teeth wereused. The first molar porcelain denture teeth were separatedinto 3 material groups; Group 1: Heat-polymerized (HP), Group2: Autopolymerizing (AP), and Group 3: Polyamide (PA) (n=21).Then, all material groups were divided into 3 subgroups (n=7)representing different surface treatment method; Control, Airborne abrasion, Er: YAG laser. A universal testing machine wasused for determining the tensile bond strength (MPa) of theporcelain denture teeth to surface treated denture base andrepair materials. The crosshead speed was set of 0.5 mm/min.Two-way ANOVA and post-hoc Tukey’s HSD was used for statically analyses (α=0.05). The effects of the surface treatmentwere observed by scanning electron microscopy (SEM).Results: The polyamide (PA) has significantly higher(p< 0.05) tensile bond strength than the Heat-polymerized(HP) and Auto-polymerizing acrylic (AP). Polyamide (PA) withlaser surface treatment (9.89 MPa) showed highest tensilebond strength. The lowest tensile bond strength was determined control group (6.38 MPa) of auto-polymerizing (AP).Surface treatments showed no significant difference.Conclusion: Superior tensile strength was found polyamidedenture base and different surface treatments not affect thetensile strength of porcelain teeth.

Özet

Amaç: Bu çalışmanın amacı, porselen protez dişelere uygulanan farklı yüzey işlemlerinden sonra iki farklı protez kaide (poliamid ve ısı ile polimerize akrilik) ve tamir materyali (otopolimerize akrilik) ile arasındaki gerilme kuvvetini değerlendirmektir. Gereç ve Yöntem: Bu çalışmada 63 adet aynı şekil ve renk mandibular sağ birinci molar porselen protez dişleri kullanıldı. Birinci molar porselen protez dişler 3 materyal grubuna ayrıldı; Grup 1: Isı polimerizasyonu (HP), Grup 2: Otopolimerize akrilik (AP) ve Grup 3: Poliamid (PA) (n=21). Daha sonra, tüm poselen dişler yüzey işleme yöntemine göre 3 alt gruba ayrıldı; Kontrol, Kumlama, Er: YAG lazer. Gerilme kuvveti (MPa) universal test makinesi kullanılarak (0.5 mm/dak) tespit edildi. Gerilme değerlerinin ortalama ve standart sapması hesaplandı ve tüm veriler two-way ANOVA ve post-hoc Tukey HSD ile analiz edildi. Güven aralığı α=0.05 olarak belirlendi. Yüzey işlemlerinin etkileri taramalı elektron mikroskobu (SEM) ile incelendi. Bulgular: Poliamid kaide materyali diğer materyallere göre önemli derecede yüksek gerilme değeri sağladı (p 0,05). Sonuç: En fazla gerilme kuvveti poliamid kaide materyalinde bulunmuştur. Farklı yüzey uygulamalarının porselen dişlerin gerilme değerlerini etkilemediği görülmüştür.
