Amaç: Bu çalışmanın amacı, CAD/CAM ile şekillendirilen kaide materyalleri (PMMA/PEEK) ve ısı ile polimerize olan geleneksel kaide materyalinin yüzey ve fiziksel özelliklerinin incelenmesidir. Yöntem: Bu çalışmada CAD/CAM ile frezelenmiş iki farklı kaide polimeri (Yamahachi PMMA Disk ve Juvora Dental Disk PEEK) ve bir adet ısı ile polimerize olan akrilik rezin (Meliodent PMMA) kullanıldı. Toplam 120 adet test örneği (n=10) hazırlandı. Test örneklerinin yarısı distile suda bekletildi. Diğer yarısına ise, termal döngü uygulandı. Termal döngüden sonra tüm test örneklerinin yüzey pürüzlülüğü, su emilimi ve çözünürlüğü değerlendirildi. Bulgular: CAD/CAM ile üretilen PMMA test örnekleri en düşük yüzey pürüzlülüğü değerleri (0.31±0.06 µm) göstermiştir. CAD/CAM ile üretilen PEEK grubu su emilimi açısından diğer iki grup test örneklerine göre istatistiksel olarak anlamlı daha düşük bulgular vermiştir (p<0.001). Termal döngü uygulaması test örneklerinin tümünün yüzey pürüzlülüğü, su emilimi ve çözünürlüğü değerlerini anlamlı derecede etkilememiştir (sırasıyla p=0.22; p=0.912; p=0.062). Sonuç: CAD/CAM ile üretilen PMMA ve PEEK materyalleri, ısı ile polimerize olan akrilik rezin test örnekleri ile kıyaslandığında daha iyi fiziksel özellikler göstermiştir.

Comparison of some physical properties of CAD/CAM millled PEEK and PMMA with conventional denture base materials

Aim: The purpose of this study was to investigate the surface and physical properties of base materials (PMMA/PEEK) formed with CAD/CAM and heat polymerized conventional base material. Method: In this study, two different base polymers milled with CAD/CAM (Yamahachi PMMA Disk and Juvora Dental Disk PEEK) and one heat polymerized acrylic resin (Meliodent PMMA) were used. A total of 120 test samples (n = 10) were prepared. Half of the test specimens were stored in distilled water. While the other half, the thermal cycle was applied. After the thermal cycling; surface roughness, water absorption and solubility of all test specimens were evaluated. Results: The PMMA test specimens produced with CAD/CAM showed the lowest surface roughness values (0.31 ± 0.06 µm). The PEEK group produced by CAD/CAM showed statistically significantly lower results in terms of water absorption than the other two groups (p<0.001). Thermal cycling did not significantly affect the surface roughness, water sorption and solubility values of all test samples (respectively, p= 0.22; p= 0.912; p = 0.062). Conclusion: PMMA and PEEK materials produced by CAD/CAM showed better physical properties compared to heat-polymerized acrilic resin test specimens.
