İki Rezin Simanın Farklı Metal Alaşımlara Makaslama Bağlanma Dayanımlarının Karşılaştırılması
Bu çalışmanın amacı rezin içerikli simanların bilgisayar destekli tasarım/ bilgisayar destekli üretim (CAD/CAM) ve lazer sinterleme ile üretilen metal alaşımlara makaslama bağlanma dayanımlarını (SBS) incelemekti. 160 adet metal alaşım disk şeklinde hazırlanan numuneler 4 gruba ayrıldı: Cr-Co (sert metal, HM; yumuşak metal, SM; lazer sinterleme, LS), and titanyum metal (TM). Numunelere 50 μm alüminyum oksit ile kumlama yapılmış ve adeziv rezin siman ile self-etch/self adeziv rezin siman kullanılmak üzere iki alt gruba ayrılmıştır. Makaslama bağlanma dayanımı ölçülmeden önce numunelerin yarısına termal döngü (10000 döngü, 5-55°C) uygulanmıştır. Termal döngü 0 olan grupların içinde en yüksek SBS değeri (18.3 ± 3 MPa) self etch/self adeziv rezin siman ile HM arasında görülmüştür (P < 0.05). Termal döngü 10000’de ise simanların SM ve LS gruplarında anlamlı derecede farklılık vardır (p<0.05). GL grubunda termal döngü açısından anlamlı bir fark olmamasına karşın ME grubunda fark anlamlıdır. Adeziv rezin siman termal döngüye karşı self etch/self adeziv rezin simandan daha dirençli bulunmuştur.

A Comparison of Shear Bond Strength of Two Resin Cements to Different Metal Alloys
The aim of this study was to investigate the shear bond strength (SBS) of resin cement to different metals manufactured by computer aided design and computer aided manufacturing (CAD/CAM) and laser sintering. One hundred and sixty specimens were prepared and divided into four groups of metal alloy discs: Cr-Co (hard metal, HM; soft metal, SM; laser sintering, LS), and titanium metal (TM). Specimens were sandblasted with 50 μm aluminum oxide and divided into two subgroups, each of which received one of the following luting cements: Adhesive resin cement, Self-etch/self-adhesive resin cement. 50% of the specimens were thermal cycled (10000 cycles, 5–55°C) before being tested for shear bond strength. At thermocycle 0, the highest SBS value (18.3 ± 3 MPa) was found with the self-etch/self-adhesive cement of the HM group (P < 0.05). At thermocycle 10000, there was a significant difference between the cements in the SM and LS groups (p<0.05). Whereas there was no significant difference between the GL groups in terms of thermal cycling, there was a significant difference in the ME groups. The adhesive resin cement was found to be more resistant to thermal cycling than self-etch/self-adhesive cement.
