Farklı üretim teknikleri ile elde edilen Cr-Co metal-seramik örneklerin bağlanma dayanımının değerlendirilmesi
Öz
Amaç: Dört farklı
üretim tekniği (döküm, tekrarlanan döküm, CAD-CAM ve seçici lazer sinterleme)
ile elde edilen Cr-Co metal seramik örneklerin (n:10) farklı pH ortamlarındaki
(pH:2.3 ve pH:6.5) yapay tükrükte farklı bekletme süreleri sonundaki bağlanma
dayanımını değerlendirmektir.
Gereç ve Yöntemler:Bu çalışmada 4
grupta toplam 200 Cr-Co metal seramik örnek 4 farklı teknik (döküm, tekrarlanan döküm,
CAD-CAM ve seçici lazer sinterleme) ile hazırlanmıştır. Ayrıca SEM analizinde
kontrol grubu olarak kullanılmak üzere Cr-Co metal alaşım örneklerinden 1’er
adet her grup için üretilmiştir. Örnek sayısı her bir grup için n=10 olarak
belirlenmiştir. Metal seramik örneklerin iki farklı pH ortamındaki (pH 2.3 ve
pH 6.5) yapay tükrükte 15 ve 30 gün
bekletilme sonrası makaslama bağlanma dayanımı ölçülmüştür. Her gruptan birer
örnek taramalı elektron mikroskobu (SEM) analizi ile yüzey değişikliği ve
kırılma morfolojisi açısından değerlendirilmiştir.
Bulgular:Bağlanma dayanımı bakımından seçici
lazer sinterleme tekniği CAD-CAM ve tekrarlanan döküm tekniğinden daha iyi
bulunmuştur. En yüksek bağlanma dayanımı değerini döküm tekniği göstermiştir. 2.3
pH değerinde daha düşük bağlanma dayanımı bulunmuştur. Her iki pH değerinde de 30
günlük bekletme süresinde, 15 günlük bekletme süresine göre daha düşük bağlanma
dayanımı sonuçları bulunmuştur.
Sonuçlar:Döküm
tekniği ilk tercih olmakla birlikte; seçici lazer eritme tekniği, CAD-CAM
tekniğine kıyasla bağlanma dayanımı bakımından tercih edilebilir. Ortamın
asiditesinin bekletme süresiyle doğru orantılı olarak materyalin direncini
azalttığı sonucuna ulaşılabilir. Bu nedenle ani pH değişimlerine karşı
metal-porselen ekspoz alanlarının ağızda bekletilmemesi gerektiği
düşünülebilir.
Anahtar Kelimeler:Seçici lazer sinterleme, metal-ceramic, iyon salınımı, CAD/CAM,
bağlanma dayanımı.

Background:In this study, the shear bond strength of the
metal ceramic samples obtained by 4 different techniques (casting, repeated
casting, CAD-CAM and selective laser sintering) were measured at 15 days and 30
days after immersed in the artificial saliva at two different pH (pH:2.3 ve pH:6.5) environments.
Methods:In this study, 200 Cr-Co metal ceramic
samples in 4 groups were obtained by 4 different techniques (casting, repeated
casting, CAD-CAM and selective laser melting). Four Cr-Co metal samples from each
group were manufactured for SEM analysis as control groups. Ten samples from
each group were determined for all groups (n=10). The shear bond strength of
the metal ceramic samples were measured after immersed in artificial saliva at two
different pH (pH 2.3 and pH 6.5) for 15 and 30 days. One sample from each group
was evaluated by scanning electron microscopy (SEM) analysis in terms of
surface change and fracture morphology.
Results:In terms of bond strength selective
laser sintering technique found to be better than the CAD-CAM and repeated casting technique. The
highest bond strength values were found for the casting technique. The shear
bond strength was found to be lower at 2.3 pH value. The shear bond strength
value was found to be lower for 30 days than 15 days at both pH values.
Conclusions:Besides the
casting technique determined as the first preference,the selective laser
technique can be preferred compared to the CAD-CAM technique in terms of shear
bond strength. The acidity of the environment in direct proportion to the
immersion period can both decrease the strength of the material. It was
concluded that the metal-ceramic exposed areas should not be left in the mouth
against the instant pH changes.
Keywords:Selective laser sintering, metal-ceramic, ion
release, CAD/CAM, bond strength.
