Comparisons of the Bonding Strength of Heat-Treated Composite Resins to Different CAD/CAM Ceramics

Abstract

Aim: The aim of this study was to evaluate the bonding strength of pre-heated composite resins used in the repair of CAD/CAM ceramic materials. Material and Method: Samples prepared from Feldspathic ceramic (VITABlocs Mark II, VITA Zahnfabrik, Germany), Hybrid ceramic (Vita Enamic, VITA Zahnfabrik, Germany), Zirconia-reinforced lithium silicate ceramic (Vita Suprinity, VITA Zahnfabrik, Germany) CAD/CAM materials were fixed in autopolymerised acrylic. The samples were separated into two groups (n=10) according to the temperature of the composite resin. As the surface procedure, 9% hydrofluoric porcelain acid (Ultradent Products Inc., Cologne, Germany) was applied to the ceramic surface for 20 seconds. In accordance with the manufacturer’s instructions, Monobond was applied for 20 seconds and Heliobond for 10 seconds. The composite resins at different temperatures (23±2°C, 65°C) were placed in silicone moulds (4mm diameter, 2mm height) and polymerised. The bonding strength of the samples was measured in a Universal test device and the data were analyzed using the Two-way ANOVA and Tukey test in SPSS vn. 23.00 software. Results: The highest bonding strength value (60.58 MPa) was obtained in Group VS-RT and the lowest (4.36 MPa) in Group VB-PHT. No significant difference was observed between Group VB and Group VE (p>0.05). A significant difference was determined in Group VS. Conclusion: Within the limitations of the study, the results showed that heat-treated composite resin reduced the bonding strength of Vita Suprinity material and increased the bonding strength of Feldspathic and Vita Enamic ceramics.

Amaç: CAD/CAM seramik materyalinin tamirinde kullanılan kompozit rezinlere uygulanan ön ısıtma işleminin bağlantı dayanımının değerlendirilmesi amaçlandı. Materyal-Metod: Feldspatik seramik (VITABlocs Mark II, VITA Zahnfabrik, Almanya), Hibrit seramik (Vita Enamic, VITA Zahnfabrik, Almanya), Zirkonya ile güçlendirilmiş lityum silikat seramik (Vita Suprinity, VITA Zahnfabrik, Almanya) CAD/CAM materyallerden hazırlanan örnekler, otopolimerizan akrilikle sabitlendi. Örnekler kompozitin rezinin sıcaklığına göre iki gruba ayrıldı (n=10). Yüzey işlemi olarak, %9 hidroflorik porselen asit (Ultradent Products, Inc., Köln, ALMANYA) seramik yüzeyine 20 sn uygulandı. Üretici firma talimatları doğrultusunda (60 sn. Monobond, 10 sn Heliobond) uygulandı. Farklı sıcaklıklardaki kompozit rezin (23±2 °C, 69 °C) yüzeylere silikon kalıplar yardımıyla (4 mm çap, 2 mm yükseklik) yerleştirildi ve polimerize edildi. Örneklerin bağlanma dayanımı, Universal test cihazında ölçüldü ve veriler SPSS 23.00 uygulamasıyla Two-way ANOVA ve Tukey testi kullanılarak analiz edildi Bulgular: En yüksek bağlanma dayanımı değeri (60,58 MPa) GroupVS- RT grubunda görülürken, en düşük bağlanma dayanımı değeri (4,36 MPa) GrupVB-PHT grubunda elde edilmiştir. Gruplar arasında GrupVB ve GrupVE’de anlamlı farklılık görülmezken (p>0,05), GrupVS’de anlamlı farklılık bulunmuştur (p<0,05). Çıkarım: Çalışmanın sınırları dahilinde; ısıl işlem uygulanan kompozit rezin, Vita Suprinity materyali için bağlanma dayanımını azalırken, Feldspatik ve Vita Enamic seramikler için arttırmıştır.
