The Effect of Repeated Firings on the Color Change of Metal Based Ceramics Produced with Different Techniques
Öz
Aim: The purpose of this study was to compare the effects of repeated firings on the color change of metal-ceramic restorations with different porcelain thicknesses and metal coping fabrication methods.
Material and Methods: A total of 30 disc-shaped samples of 1 mm thickness and 13 mm diameter were produced using selective laser melting (SLM) and conventional casting (CC) methods. Feldspathic porcelain in thicknesses of 0.7, 1.2 and 1.7 mm were then applied to each group (n = 10). Each sample was subjected to five firing processes. After each repeated firing process, color measurement was performed using a spectrophotometer. One-way analysis of variance was used for the statistical analyses and Tukey’s test was used for post-hoc analyses (p = 0.05).
Results: There were significant differences in color changes both groups (p < 0.05). The SLM samples underwent more color changes than the CC samples.
Conclusion: As a result of the study it was determined that repeated firings and an increase in the porcelain thickness enhanced color changes. Moreover, the color of SLM samples changed more than the CC samples.

Tekrarlanan Fırınlamaların Farklı Tekniklerle Üretilen Metal-Seramik Restorasyonların Renk Değişimine Etkisi
Öz
Amaç: Bu çalışmanın amacı, farklı porselen kalınlıklarına ve metal altyapı oluşturma yöntemlerine sahip metal-seramik restorasyonların tekrarlayan pişirme işlemlerinin renk değişimleri üzerindeki etkilerini karşılaştırmaktır.
Gereç ve Yöntemler: Toplam 30 disk şeklindeki örnek, seçici lazer eritme (SLM) ve geleneksel döküm (CC) yöntemleri kullanılarak 1 mm kalınlığında ve 13 mm çapında üretildi. Her gruba (n = 10) sırasıyla 0,7, 1,2 ve 1,7 mm kalınlıklarında feldspatik porselen uygulandı. Her örnek beş pişirme işlemine tabi tutuldu. Her tekrarlayan pişirme işleminden sonra, bir spektrofotometre kullanılarak renk ölçümü yapıldı. İstatistiksel analizler için tek yönlü varyans analizi kullanıldı ve post-hoc analizler için Tukey testi kullanıldı (p = 0.05).
Bulgular: Her iki grup arasında renk değişikliklerinde önemli farklılıklar vardı (p < 0.05). SLM örnekleri CC örneklerine göre daha fazla renk değişikliği gösterdi.
Sonuç: Çalışmanın sonucunda, tekrarlanan fırınlamaların ve porselen kalınlığının artmasının renk değişimini de artırdığı belirlendi. Ayrıca, SLM örneklerinin rengi CC örneklerinden daha fazla değişti.
