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 bawah
omega 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.

 

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 mm and 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.
