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.

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.
