Abstract

Mekanisme perawatan dengan Multiloop Edge Wise (MEAW) efisien dalam melakukan koreksi maloklusi berat dengan defleksi tekanan yang sangat rendah. Tujuan pemaparan kasus adalah evaluasi perawatan crowding berat disertai palatal bite menggunakan multiloop edgewise archwire. Seorang laki laki 15 tahun dengan maloklusi Angle kelas I tipe 1,4, skeletal kelas I dengan bimaksilari retrusif disertai bidental protrusif. Crowding berat pada regio anterior dan posterior serta palatal bite pada gigi 12, 11, 21, 22 terhadap 42, 41, 31, 32, scissor bite pada gigi 15 terhadap 45, overjet 6,21 mm dan overbite 6,04 mm. Bentuk lengkung gigi pada rahang atas parabola asimetri sedang pada rahang bawahomega asimetri. Lengkung gigi regio posterior mengalami kontraksi lateral dan lengkung gigi kearah anterior mengalami protraksi. Perawatan kasus dilakukan dengan menggunakan alat cekat teknik Edgewise dengan multiloop pada regio anterior dan posterior disertai pencabutan empat gigi premolar pertama. Hasil perawatan setelah 6 bulan menunjukkan crowding, palatal bite, dan scissor bite terkoreksi. Overjet menjadi 4,20 mm dan overbite 3,90 mm. Bentuk lengkung pada rahang atas dan rahang bawah menjadi parabola simetris. Jarak intermolar rahang atas bertambah sebesar 2,11 mm dan rahang bawah bertambah sebesar 1,22 mm. ABSTRACT: Effectiveness of multiloop edge wise arch in severe crowded case accompanied by palatal bite. MEAW appliance is a tehnique which is able to efficiently treat many cases including severe crowding with very low load deflection. The objectives of this study is to evaluate the treatment of severe crowding malocclusion with palatal bite using multiloop edgewise archwire. A 15 years old man with Angle class I type 1,4 malocclussion, class I sceletal with bimaxillary retrusion and bidental protusion. Severe crowding malocclusion in anterior and posterior region, palatal bite in 12, 11, 21, 22 to 42, 41, 31, 32, scissor bite in 15 to 45, overjet 6,21 mm and overbite 6,04 mm. asymmetry in both of dental arch, but the shape of the upper arch was parabola and lower arch was omega. Contraction of dental arch in posterior region and protraction in anterior region. This case was treated with extraction of four first premolar using multiloop edgewise arcwire tehnique, the loops were placed in anterior and posterior region. After six month of treatment the result showed that MEAW could correct severe crowding, palatal bite and scissor bite. Overjet became 4,20 mmand overbite became 3,90 mm. Shape of upper and lower dental arch became symmetric parabola. Upper intermolar increased 2,11 mm and lower intermolar 1,22 mm.

Abstract

Background: Fixed orthodontic treatment needs several types of wire to produce biomechanical force to move teeth. The use orthodontic wire within the mouth interacts with saliva, causing the release of nickel and chromium ions. Purpose: The study was aimed to examine the effect of immersion time in artificial saliva between special type of Australian wire and stainless steel on the release of nickel and chromium ions. Methods: Thirty special type Australian wires and 30 stainless steel wires were used in this study, each of which weighed 0.12 grams. The wires were immersed for 1, 7, 28, 35, 42, and 49 days in artificial saliva with a normal pH. The release of ions in saliva was examined using Atomic Absorption spectrophotometry. Results: The result indicated that the release of nickel ions on special type of Australian wire was larger than that on stainless steel wire (p<0.005), there were differences in the release of the amount of nickel ions on special type of Australia in different immersion time, and there was a correlation between the types of wire and immersion time. Nickel ions released from the special type of Australian wire detected on the 7th day of immersion and reached its peak on the 35th day, while from stainless steel wire were detected on the 49th day of immersion. The released of chromium ions from the special type of Australian wire and stainless steel wire were not detected until the 49th day of immersion. Conclusion: The release of nickel ions were highest on the 35th day of immersion in special type of Australian wire and they were detected on the 49th day in stainless steel wire. The release of chromium ions were not detected until 49th day of immersion in special type of Australian and stainless steel wire.Latar belakang: Perawatan ortodonti cekat memerlukan beberapa macam kawat untuk menghasilkan kekuatan biomekanika yang sesuai dalam menggerakkan gigi. Pemakaian kawat ortodonti di dalam mulut dapat bereaksi dengan saliva sehingga menyebabkan terjadinya pelepasan ion nikel dan kromium. Tujuan: Penelitian ini bertujuan untuk meneliti pengaruh waktu perendaman dalam saliva buatan terhadap pelepasan ion nikel dan kromium antara kawat Australia tipe spesial dengan kawat stainless steel. Metode: Penelitian ini menggunakan 30 buah kawat Australia tipe spesial dan 30 buah kawat stainless steel dengan berat tiap kawat 0,12 gram. Kawat direndam selama 1, 7, 28, 35, 42 dan 49 hari dalam saliva buatan pH normal. Pemeriksaan pelepasan ion pada saliva menggunakan spektrofotometri serapan Atom. Hasil: Pelepasan ion nikel pada kawat Australia tipe spesial lebih besar dibandingkan dengan kawat stainless steel, terdapat perbedaan pelepasan jumlah ion nikel pada kawat Australia tipe spesial antara waktu perendaman dan terdapat interaksi antara jenis kawat dengan waktu perendaman. Ion nikel yang terlepas pada kawat Australia tipe spesial mulai terdeteksi pada hari ke-7 perendaman dan mencapai jumlah tertinggi pada hari ke-35 sedangkan pada kawat stainless steel mulai terdeteksi pada perendaman hari ke-49. Pelepasan ion kromium pada kawat Australia tipe spesial dan kawat stainless steel tidak terdeteksi sampai perendaman hari ke-49. Simpulan: Pelepasan ion nikel pada kawat Australia tipe special terdeteksi paling tinggi pada lama perendaman hari ke tiga puluh lima, kawat stainless steel terdeteksi pada lama perendaman hari ke empat puluh sembilan. Pelepasan ion kromium pada kawat Australia tipe special dan stainless steel tidak terdeteksi sampai lama perendaman hari ke empat puluh sembilan.
