Abstract

Aim: Purpose of the study; to evaluate the effect of metal primer, Nd: YAG laser and sandblasting surface treatments on shear bond strength between Co-Cr alloy surface and veneer resin and acrylic artificial teeth materials. Material and Methods: In the study, Co-Cr metal alloy (Magnum H60, Italy), two different veneer resins (Sinfony and VisioCem, 3M ESPE, Germany) and two different artificial teeth (Acrylux, Italy and Ivoclar Vivadent, Liechtenstein) were used. 240 Co-Cr samples were sandblasted with Al2O3. Samples were divided into 4 groups for resin and artificial dental materials and 6 subgroups for surface treatments (n=10). No surface treatment was applied to group 1 (control). Different surface treatments were applied to other groups (Group 2:metal primer, Group 3:rocatec, Group 4: Nd:YAG laser, Group 5: Nd:- YAG laser+rocatec, Group 6: Nd:YAG laser+metal primer). After finishing with 2 different artificial teeth and 2 different veneer resins, the bond strength was evaluated with shear bond test. Results: The highest bonding values were seen in laser+rocatec groups and the lowest values in control groups. Different surface treatments and different veneer materials were effective on the bonding of the framework infrastructure and the resin superstructure (P 0.05). Conclusions: Applying different surface treatments on the metal surface increases the shear bonding values. Applying a laser to the metal surface and, rocatec or metal primer with the laser increases the bond strength.

Özet

Amaç: Çalışmanın amacı; metal primer, Nd:YAG lazer ve kumlama yüzey işlemlerinin, Co-Cr alaşım yüzeyi ile kaplama rezini ve akrilik yapay diş materyalleri arasındaki makaslama bağlantı dayanımına etkisini değerlendirmektir. Gereç ve Yöntem: Çalışmada Co-Cr metal alaşımı (Magnum H60, İtalya), iki farklı kaplama rezini (Sinfony ve VisioCem, 3M ESPE, Almanya) ve iki farklı yapay diş (Acrylux, İtalya ve Ivoclar Vivadent AG, Liechtenstein) kullanıldı. 240 adet Co-Cr örnek Al2O3 ile kumlandı. Örnekler rezin ve yapay diş materyalleri için 4 gruba ve yüzey işlemleri için 6 alt gruba ayrıldı (n=10). Grup 1’e yüzey işlem uygulanmadı (kontrol). Diğer gruplara ise farklı yüzey işlemleri uygulandı (Grup 2:metal primer, Grup 3:rocatec, Grup 4: Nd:YAG lazer, Grup 5: Nd:YAG lazer+rocatec ve Grup 6: Nd:YAG lazer+metal primer). 2 farklı yapay diş ve 2 farklı kaplama rezin ile bitim yapıldıktan sonra bağlantı dayanımı makaslama bağlantı testi ile değerlendirildi. Bulgular: En yüksek bağlantı değerleri, lazer+rocatec gruplarında, en düşük değerler ise kontrol gruplarında görüldü. Farklı yüzey işlemleri ve farklı kaplama materyalleri, iskelet alt yapı ile rezin üst yapı bağlantısında etkili oldu (P 0.05). Sonuçlar: Metal yüzeyine farklı yüzey işlemleri uygulamak makaslama bağlantı değerlerini arttırmaktadır. Metal yüzeyine lazer ve lazerle birlikte rocatec veya metal primer uygulanması bağlantı dayanımını arttırmaktadır.
