Öz Purpose: Rough intaglio surfaces of overdentures have a greatimportance since rough surfaces may cause microbial dental plaque accumulation.Thus, the aim of the present study was determination the surfaceroughness values of 5 different materials that are used to fixation of dentalimplant attachment housings to overdentures. Material andMethod: 84 specimens with 10X4 mm diameters were preparedfrom 5 different materials. The surface roughnesses of the materials wereanalyzed using by a tactile profilometer. Thedata (Ra) was analyzed using one-way ANOVA and Tukey’s post-hoc comparison. The significance level was set as α=0.05. Results: There was statistically significant difference between thegroups. While the roughest surface was observed in the PSC and UGH groups, the least rough surface wasobserved in the QU GROUP. However, there was statistically no differencebetween the QU, PHC, QULC, TRF and TRF+RH groups. Conclusion: In the limitations of the present study, it may be suggesteduse ofQU, PHC, QULC, TRF and TRF+RHinstead of PSC and UGH inorder to have least rough intaglio surfaces for overdentures. However, thispoint of views should be approved with clinical studies.Keywords: Surface roughness, Overdenture, Overdenture attachment housingİMPLANT DESTEKLİ OVERDENTURE PROTEZLERETUTUCU PARÇALARIN SABİTLENMESİNDE KULLANILAN BEŞ FARKLI MATERYALİN YÜZEYPÜRÜZLÜLÜĞÜNÜN DEĞERLENDİRİLMESİAmaç: Overdenture protezlerde, dental implantlarakomşu olan iç yüzeylerin pürüzlülüğü, bu bölgelerde mikrobiyal plak tutunmasınayol açtığından büyük önem taşımaktadır. Bu nedenle çalışmamızın amacı,overdenture protezlerde tutucu parçaların proteze sabitlenmesinde kullanılan 5farklı materyalin yüzey pürüzlülük değerlerini belirlemektir. Gereç ve Yöntem: Çalışmada, beşfarklı materyal kullanılarak 10x3 mm ebatlarında 84 adet örnek hazırlandı.Örneklerin yüzey pürüzlülükleri profilometre cihazı kullanılarak üç farklınoktadan ölçüldü. Elde edilen veriler (Ra)tek yönlü ANOVA ve Tukey HSD testleri ile istatiksel olarak değerlendirildi. İstatistikselanaliz anlamlılık düzeyi α=0.05 olarak belirlendi.Bulgular: İstatiksel olarak gruplar arasındaönemli farklılıklar bulgulandı. En fazla pürüzlülük değeri PSC ve UGHgruplarında gözlenirken, en düşük değer QU grubunda gözlendi. Bununla birlikte,QU, PHC, QULC, TRF ve TRF+RH grupları arasında istatiksel olarak farklılık bulgulanmadı.Sonuç: Bu çalışmanın sınırları dahilinde,daha az pürüzlü intaglio yüzeyler için overdenture protezlere tutucuataçmanların sabitlenmesinde UGH ve PSC materyalleri yerine, PHC, QU, QULC, TRFve TRF+RH kullanılması önerilebilir. Bununla birlikte, konu ile ilgili klinikçalışmalar önerilir.Anahtar Kelimeler: Yüzey pürüzlülüğü, Overdenture,Overdenture tutucu parçası
