Abstract
Amaç: Bu çalışmanın amacı, protetik
tedavilerde kullanılan döküm ve fabrikasyon manyetik ataşman sistemlerinin,
korozyona karşı dirençlerinin incelenmesidir.
Gereç ve Yöntem: Korozyon testi için, ağırlıkça
%39,5 platin, %59,75 demir ve %0,75 niobyum içeren döküm manyetik ataşmanlar
ile neodmiyum, demir ve boron içeriğe sahip fabrikasyon Hilop manyetik ataşman
sistemleri, %1’ lik laktik asit ve %0,9’ luk NaCl solüsyon içerisinde 14 gün
boyunca bekletilmiş (n:8). Örneklerden solüsyonlar içerisine salınan demir,
platin, neodimyum, bor ve niobyum iyonlarının miktarı indüktif olarak eşleşmiş
plazma kütle spektroskopi (ICP-MS) yöntemiyle tayin edilmiştir.
Bulgular: Her iki manyetik ataşman
sisteminde de en fazla solüsyon içerisine salınan ve korozyona neden olan
element demir olarak tespit edilmiştir. Ayrıca her iki ortamda da döküm manyetik
ataşman sistemi korozyona karşı en dirençli sistem olarak tespit edilmiştir.
Sonuç: Paslanmaz çelik ile kaplama
fabrikasyon manyetik ataşman sistemlerini korozyona karşı korusada döküm
mıknatısların içeriğindeki yüksek orandaki platin malzemeyi korozyona karşı
daha dirençli hale getirmiştir.

Abstract
Objectives: The
aim of this study was to compare the corrosion resistance of castable and
fabrication magnetic attachments systems used in prosthetic rehabilitation.
Material and Methods: For corrosion test, castable magnetic attachments containing 39.5%
platinum, 59.75% iron and 0.75% niobyum by weight and fabricated magnetic
attachment system, Hilop, with neodymium, iron and boron content were immersed
in 1% lactic acid and 0,9% NaCI for 14 days (n:8). The released iron, platinum,
neodimyum, boron and niobyum ions in the solutions from the samples were
examined by inductively coupled plasma mass spectroscopy (ICP-MS) methods.
Results: Iron
was found the highest released element into the both solutions for all
attachment systems and causing corrosion. In addition, castable magnetic
attachment system was found to be the most resistant to corrosion in both
environments.
Conclusion: Coating
with stainless steel makes the fabricated magnetic attachment system resistant
to corrosion, but the high platinum content made the castable magnets more
resistant to corrosion.
