This study investigates the effects of different production durations in 3D-printed temporary restorations on physical and surface properties such as color parameters, surface roughness, hardness, and contact angle. A total of 30 specimens (10 × 10 × 2 mm) were fabricated using a methacrylate-based temporary restoration resin in A1 shade, with three production times (20, 40, and 60 minutes). All samples underwent a standard post-curing process. Color measurements were performed using a spectrophotometer, surface roughness was measured with a contact profilometer, micro-hardness with a Vickers hardness tester, and contact angle by the sessile drop method. Data were analyzed using one-way and two-way ANOVA (p < 0.05). No statistically significant differences were found in surface roughness among groups, although a decreasing trend was observed with longer production times. Hardness and contact angle values increased significantly with extended production time (p < 0.05). Among color parameters, L*, b*, C, and h values showed significant variations, whereas the a* value remained unchanged. In conclusion, production time has a significant influence on surface and physical properties, particularly hardness and wettability, and optimizing it may enhance the durability and aesthetic performance of temporary restorations in clinical applications.

ÜRETİM SÜRESİ FARKLILIKLARININ 3B YAZICIYLA HAZIRLANAN GEÇİCİ RESTORASYONLARIN RENK VE YÜZEY ÖZELLİKLERİNE ETKİSİ

Öz

Bu çalışma, 3B baskı yöntemiyle üretilen geçici restorasyonlarda üretim süresinin renk, yüzey pürüzlülüğü, sertlik ve temas açısı gibi fiziksel ve yüzeysel özellikler üzerindeki etkisini incelemektedir. A1 tonunda metakrilat bazlı rezinden, 20, 40 ve 60 dakikalık üç farklı üretim süresinde toplam 30 adet 10 × 10 × 2 mm boyutlarında numune hazırlanmış ve tümüne standart post-kür işlemi uygulanmıştır. Renk ölçümleri spektrofotometreyle, pürüzlülük profilometreyle, mikrosertlik Vickers cihazıyla, temas açısı ise “sessile drop” yöntemiyle belirlenmiştir. Veriler tek ve çift yönlü ANOVA ile analiz edilmiştir (p < 0,05). Gruplar arasında pürüzlülük farkı anlamlı bulunmazken, süre arttıkça azalma eğilimi gözlenmiştir. Sertlik ve temas açısı üretim süresiyle birlikte anlamlı biçimde artmıştır (p < 0,05). Renk parametrelerinde L*, b*, C ve h değerleri anlamlı farklılık göstermiş, a* değeri sabit kalmıştır. Sonuç olarak, üretim süresi özellikle sertlik ve yüzey ıslanabilirliği üzerinde belirleyici olup, sürenin optimize edilmesi restorasyonların estetik ve mekanik performansını artırabilir.
