Poliamid, Protez Kaidesi, Isıl DöngüÖzet
Artan sayıda ürün fleksibl, poliamid protez kaide materyalleri olarak pazarlanmaktadır. Ancak bu materyallerin uygulanmasını destekleyen sınırlı sayıda bilimsel araştırma vardır ve bu materyallerin klinik kullanımı için çalışmalara ihtiyaç vardır. Bu çalışmanın amacı, bu poliamid protez kaide materyallerini geleneksel PMMA ile karşılaştırmaktı. Bu araştırmada, konvansiyonel protez kaide reçine materyaline (Meliodent, Heat Cure) alternatif olarak dört adet PA bazlı protez kaide materyali (Bre-flex, Tcrystal, Valplast, Deflex) temas açısı değerlendirilerek in vitro olarak incelendi, C.albicans ve S.mutans'ın termosikl işlemi öncesi ve sonrası yüzey pürüzlülüğü, su emilimi ve çözünürlüğü, mikrobiyal adezyonu incelendi. Poliamidler, temas açısı, yüzey pürüzlülüğü açısından gruplar arasında istatistiksel olarak anlamlı farklılıklar göstermiştir. TC'den sonra bir PA grubu hariç tüm gruplarda temas açısı azalır; PMMA grubunda yüzey pürüzlülüğü azalırken, PA gruplarında Ra değerleri artmış ve azalmıştır. Elde edilen sonuçlardan, hem konvansiyonel PMMA hem de PA materyallerinin protez kaide materyali olarak bir yıllık kullanım için kabul edilebilir olduğu görülmüştür. Poliamid protez kaide reçinelerinin, uzun süreli geçici hareketli protezler için geleneksel poli(metil metakrilat) reçinelere iyi bir alternatif olacağı sonucuna varılabilir. Bununla birlikte, başarılı bir tedavi sonucu elde etmek için poliamid protezlerin uygun durumlarda kullanılması için dikkatli vaka seçimi ve klinik muhakeme gereklidir.
