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, t he 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.

Bu nedenle calismamizin amaci, overdenture protezlerde tutucu parcalarin proteze sabitlenmesinde kullanilan 5 farkli materyalin yuzey puruzluluk degerlerini belirlemektir. Gerec ve Yontem: Calismada, bes farkli materyal kullanilarak 10x3 mm ebatlarinda 84 adet ornek hazirlandi. Orneklerin yuzey puruzlulukleri profilometre cihazi kullanilarak uc farkli noktadan olculdu. Elde edilen veriler ( Ra ) tek yonlu ANOVA ve Tukey HSD testleri ile istatiksel olarak degerlendirildi. Istatistiksel analiz anlamlilik duzeyi α=0.05 olarak belirlendi. Bulgular: Istatiksel olarak gruplar arasinda onemli farkliliklar bulgulandi. En fazla puruzluluk degeri PSC ve UGH gruplarinda gozlenirken, en dusuk deger QU grubunda gozlendi. Bununla birlikte, QU, PHC, QULC, TRF ve TRF+RH gruplari arasinda istatiksel olarak farklilik bulgulanmadi. Sonuc: Bu calismanin sinirlari dahilinde, daha az puruzlu intaglio yuzeyler icin overdenture protezlere tutucu atacmanlarin sabitlenmesinde UGH ve PSC materyalleri yerine, PHC, QU, QULC, TRF ve TRF+RH kullanilmasi onerilebilir. Bununla birlikte, konu ile ilgili klinik calismalar onerilir. Anahtar Kelimeler: Yuzey puruzlulugu, Overdenture, Overdenture tutucu parcasi
