SURFACE ROUGHNESS OF 5 DIFFERENT MATERIALS USED FOR FIXATION OF IMPLANT ATTACHMENT HOUSINGS

Purpose: Rough intaglio surfaces of overdentures have a great importance since rough surfaces may cause microbial dental plaque accumulation. Thus, the aim of the present study was determination the surface roughness values of 5 different materials that are used to fixation of dental implant attachment housings to overdentures. Material and Method: 84 specimens with 10X4 mm diameters were prepared from 5 different materials. The surface roughnesses of the materials were analyzed using by a tactile profilometer. The data (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 the groups. While the roughest surface was observed in the PSC and UGH groups, the least rough surface was observed in the QU GROUP. However, there was statistically no difference between the QU, PHC, QULC, TRF and TRF+RH groups. Conclusion: In the limitations of the present study, it may be suggested use of QU, PHC, QULC, TRF and TRF+RH instead of PSC and UGH in order to have least rough intaglio surfaces for overdentures. However, this point of views should be approved with clinical studies.Keywords: Surface roughness, Overdenture, Overdenture attachment housing İMPLANT DESTEKLİ OVERDENTURE PROTEZLERE TUTUCU PARÇALARIN SABİTLENMESİNDE KULLANILAN BEŞ FARKLI MATERYALİN YÜZEY PÜRÜZLÜLÜĞÜNÜN DEĞERLENDİRİLMESİ Amaç: Overdenture protezlerde, dental implantlara komşu olan iç yüzeylerin pürüzlülüğü, bu bölgelerde mikrobiyal plak tutunmasına yol açtığından büyük önem taşımaktadır. Bu nedenle çalışmamızın amacı, overdenture protezlerde tutucu parçaların proteze sabitlenmesinde kullanılan 5 farklı materyalin yüzey pürüzlülük değerlerini belirlemektir. Gereç ve Yöntem: Çalışmada, beş farklı materyal kullanılarak 10x3 mm ebatlarında 84 adet örnek hazırlandı. Örneklerin yüzey pürüzlülükleri profilometre cihazı kullanılarak üç farklı noktadan ölçüldü. Elde edilen veriler (Ra) tek yönlü ANOVA ve Tukey HSD testleri ile istatiksel olarak değerlendirildi. İstatistiksel analiz anlamlılık düzeyi α=0.05 olarak belirlendi.Bulgular: İstatiksel olarak gruplar arasında önemli farklılıklar bulgulandı. En fazla pürüzlülük değeri PSC ve UGH gruplarında 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 tutucu ataçmanların sabitlenmesinde UGH ve PSC materyalleri yerine, PHC, QU, QULC, TRF ve TRF+RH kullanılması önerilebilir. Bununla birlikte, konu ile ilgili klinik çalışmalar önerilir. Anahtar Kelimeler: Yüzey pürüzlülüğü, Overdenture, Overdenture tutucu parçası
