    Abstract
    Introduction : The aim of this study was to know the changes of dental arch in tranverse dimensions, anteroposterior and arch perimeter after fixed orthodontic treatment combined with RPE on non growing patients. Methods : Eight subjects ( non growing aged ) who required fixed orthodontic treatment combined with RPE on non growing patients. Dental changes in transverse, anteroposterior and arch perimeter were measured from dental cast study models before expansion (T1) and after expansioin (T2). Result : ANOVA test showed a statistically significant change for dental arch in transverse ( arch width ) : intercanine width was 3,10 mm standard deviation 1,85 (p<0,05), intermolar width was 6,64 mm standard deviation 2,37 (p<0,001). In anteroposterior, arch length was significantly change about 1,71 standard deviation 1,79 (p<0,05). Arch perimeter was also significantly change at 7,19 mm standard deviation 1,14 (p<0,0001).
     
    Latar Belakang : Tujuan penelitian ini adalah untuk mengetahui perubahan lengkung gigi dalam arah transversal, anteroposterior dan perimeter lengkung gigi setelah perawatan ortodonti cekat kombinasi RPE pada pasien non growing. Metode Penelitian : Sampel penelitian terdiri dari 8 pasien (usia non growing) yang membutuhkan perawatan ortodonti cekat kombinasi RPE pada pasien non growing. Perubahan lengkung dalam arah transversal, anteroposterior dan perimeter lengkung gigi diukur dari studi model sebelum ekspansi (T1) dan setelah ekspansi (T2). Hasil Penelitian : Test statistik ANOVA terlihat perubahan yang signifikan pada lengkung gigi dalam arah transversal (lebar lengkung gigi) yaitu lebar interkaninus sebesar 3,10 mm dengan standar deviasi1,85 (p<0,05), lebar intermolar 6,64 mm standar deviasi 2,37 (p<0,001). Dalam arah anteroposterior panjang lengkung berubah signifikan sebesar 1,71 standar deviasi 1,79 (p<0,05). Dan perimeter lengkung juga berubah secara signifikan sebesar 7,19 mm standar deviasi 1,14 (p<0,0001).
