Evaluation of Some Mechanical Properties of CAD/CAM Polymers (PEEK/PMMA) and Conventional PMMA Materials: An In Vitro Study
Öz: Objective: The present study aims to investigate the
mechanical properties of base materials [polymethyl methacrylate
(PMMA)/polyether ether ketone (PEEK)] fabricated with computeraided design/computer-aided manufacturing (CAD/CAM) and heatpolymerized conventional base materials. Material and Methods: Two
different base polymers milled with CAD/CAM (Yamahachi PMMA
Disk and Juvora Dental Disk PEEK) and heat-polymerized acrylic resin
(Meliodent PMMA) were used in this study. A total of 120 specimens
were prepared with 10 specimens in each subgroup of the test materials. Half of the test specimens were stored in distilled water, while the
other half were subjected to a thermal cycle. After the thermal cycle, the
flexural strength, elasticity module, and, surface hardness of all test
specimens was evaluated. The Mann-Whitney U and Kruskal-Wallis
tests were used in the analysis of the data. Results: According to the
findings of flexural strength and elasticity module of the test specimens,
the highest to lowest value ranking was as follows: CAD/CAM
PEEK>CAD/CAM PMMA>heat-polymerized PMMA. In the PMMA
group produced with CAD/CAM, surface hardness values were significantly higher in the thermocycle applied test specimens compared to
those stored in distilled water (p<0.001). Conclusion: CAD/CAM
PMMA and PEEK materials were compared with the heat-polymerized
test specimens found to show better mechanical properties.
Anahtar Kelime: CAD/CAM Polimerlerinin (PEEK/PMMA) ve Geleneksel PMMAMateryallerinin Bazı Mekanik Özelliklerinin Değerlendirilmesi:İn Vitro Çalışma
Öz: Amaç: Bu çalışmanın amacı, bilgisayar destekli tasarım/bilgisayar destekli üretim [computer-aided design/computer-aided manufacturing (CAD/CAM)] ile şekillendirilen kaide materyalleri [polimetil
metakrilat (PMMA)/polieter eter keton (PEEK)] ve ısı ile polimerize olan
geleneksel kaide materyalinin mekanik özelliklerinin incelenmesidir.
Gereç ve Yöntemler: Bu çalışmada, CAD/CAM ile frezelenmiş 2 farklı
kaide polimeri (Yamahachi PMMA Disk ve Juvora Dental Disk PEEK)
ve ısı ile polimerize olan akrilik rezin (Meliodent PMMA) kullanıldı.
Test materyallerinin her bir alt grubunda 10 örnek olmak üzere toplam
120 örnek hazırlandı. Test örneklerinin yarısı distile suda bekletildi. Diğer
yarısına ise termal döngü uygulandı. Termal döngüden sonra tüm test
örneklerinin bükülme dayanımı, elastikiyet modülü ve yüzey sertliği
değerlendirildi. Verilerin analizinde, Mann-Whitney U ve Kruskal-Wallis testleri kullanılmıştır. Bulgular: Test örneklerinin bükülme dayanımı
ve elastikiyet modülü bulgularına göre, en yüksek değerden en düşüğe
doğru sıralaması CAD/CAM PEEK>CAD/CAM PMMA>ısı ile polimerize PMMA şeklindedir. CAD/CAM ile üretilen PMMA grubu içerisinde,
distile suda bekletilen örneklere göre termal döngü uygulanan örneklerde,
yüzey sertlik düzeyi istatistiksel anlamlı olarak daha yüksek değerler
vermiştir (p<0,001). Sonuç: CAD/CAM ile üretilen PMMA ve PEEK
materyalleri, ısı ile polimerize olan test örnekleri ile kıyaslandığında daha
iyi mekanik özellikler göstermektedir.
