Abstract:

 Objective: The aim of this study is to evaluate color stability after thermal cycling of two different types of 3D printed denture teeth resin materials. Material and Method: In this study, 60 15x10x3 artificial tooth resin materials were produced with two different threedimensional printers: PowerResins Temp DentaFab, Turkey and Flexcera Smile,Desktop Health, Envision TEC systems, Germany. The final surface polishing of the samples was completed according to two methods and divided into two groups n  15. After the polishing process, the samples were artificially aged using a thermal cycle device for 5,000 cycles 5-55C. A Spectrophotometer VITA Easyshade V, Germany was used to measure color change values before T0 and after T1 thermal cycling. CIE2000 formula was used to determine ΔE values. Data were analyzed according to two-way analysis of variance statistics p 0.05. Results: When two different artificial tooth materials produced with a 3D printer were compared, the highest color change ΔE00 values were obtained with MMA free artificial tooth resin p0.001. When the surface finishing treatments were compared, it was seen that the highest ΔE00 values were obtained in the groups where polished using polishing paste p0.018. Conclusion: It has been observed that the material and surface finishing process are effective in terms of color stability after thermal cycling of removable denture artificial tooth resins with different chemical structures produced with a threedimensional printer.

 Amaç: Bu çalışmanın amacı, eklemeli üretim tekniği ile üç boyutlu 3B yazıcı ile üretilen hareketli protezlerde kullanılan farklı kimyasal yapıya sahip yapay dişlerin renk değişimine yüzey bitirme ve termal devirlendirme ile yaşlandırma işlemlerinin etkisini in vitro olarak incelemektir. Gereç ve Yöntem: Bu çalışmada üç boyutlu yazıcı ile üretilen iki farklı yapay diş rezin materyali; metilmetakrilak MMA içermeyen PowerResins Temp; DentaFab, Türkiye ve metilmetakrilat oligomer içerikli FlexceraSmile; Desktop Health, Envision TEC systems, Almanya kullanıldı. Her bir materyalden 15x10x3 mm boyutlarında 30 adet olacak şekilde, toplam 60 adet örnek hazırlandı. Örnekler farklı yüzey bitirme işlemleri uygulanması amacı ile iki gruba ayrıldı n15. Birinci grupta örneklere yüzey işlemi olarak farklı grenlerde silisyum karbür zımpara kâğıtları VIBRATITE 996A, Çin kullanılarak zımpara işlemi uygulandı. İkinci grupta ise 400 gritlik zımpara uygulamasının ardından pomza ile yüzey düzeltildi ve en son Evrensel Parlatma Pastası, Ivoclar Vivadent, Schaan, Lihtenştayn kullanılarak bitirme işlemi tamamlandı. Yüzey bitirme işlemlerinin ardından örneklerin birinci renk ölçümleri T0 bir pektrofotometre VITA Easyshade V, Almanya kullanılarak yapıldı. Ardından örneklere 5.000 kez 5-55C de termal devirlendirme yöntemi ile yapay yaşlandırma işlemi uygulandıktan sonra ikinci renk ölçümleri T1 tamamlandı. Renk farklılıklarının ΔE00 belirlenmesinde CIE2000 formülü kullanıldı. Veriler iki yönlü varyans analiz kullanılarak istatistik olarak değerlendirildi p0.05. Bulgular: Üç boyutlu yazıcı ile üretilen iki farklı yapay diş materyali karşılaştırıldığında en yüksek renk değişimi ΔE00 değerleri MMA içermeyen yapay diş rezini ile elde edilmiştir p0.001. Yüzey bitim işlemleri karşılaştırıldığında ise en yüksek ΔE00 değerlerin polisaj patı kullanılan grruplarda elde edildiği görülmüştür. p0.018. Sonuç: Üç boyutlu yazıcı ile üretilen farklı kimyasal yapıya sahip hareketli protez yapay diş rezinlerinin termal devirlendirme sonrasında renk stabilitesi açısından materyalin ve yüzey bitirme işleminin etkili olduğu görülmüştür.
