Galvanic Corrosion of Metal Injection Molded (MIM) and Conventional Brackets with Nickel-Titanium and Copper;chNickel-Titanium Archwires

Abstract

The composition and manufacturing processes involved in fabricating MIM brackets impart corrosive properties similar to those seen in the bracket-wing area of conventional brackets and may provide a measurable benefit when taking into account the increased corrosion between the bracket and brazing alloy of conventional brackets.

Corrosion behavior of ion implanted nickel-titanium orthodontic wire in fluoride mouth rinse solutions

“…Recently, the corrosion behavior of nickel-titanium orthodontic wire has been widely studied with regard to the effects of a fluorinecontaining environment [13][14][15] , various temperatures 19) , bending stress 20) and galvanic corrosion 4,21,22) . It is well known that nickel-titanium orthodontic wire has high corrosion resistance due to a protective TiO2 film formed on the top surface 23,24) .…”

Deformasi Slot Beberapa Produk Braket Stainless Steel Akibat Gaya Torque Kawat Beta Titanium

“…Siargosa dkk. 13 menyatakan bahwa pembuatan braket dengan prosedur metal injection molding (MIM) memiliki sifat mekanik yang lebih baik dibandingkan prosedur brazing. Metal injection molding (MIM) menggunakan injection molding machine seperti pada pembuatan plastik, sehingga menghasilkan bentuk geometri slot braket yang sama.…”

“…Deformasi permanen terjadi kemungkinan karena proses pembuatan braket dengan brazing sehingga, penyatuan komponen basis braket dan sayap braket yang tidak baik dan komposisi logam pembentuk braket. [12][13][14][15] Komposisi logam pembentuk braket yang mempengaruhi sifat mekanik dan fisik braket merupakan faktor terbesar dalam terjadinya deformasi braket. Komposisi material logam braket 3M adalah austenitik AISI tipe 303, braket Ormco tipe AISI 17-4 PH, dan Versadent adalah austenitik.…”
