PENGARUH PERAWATAN ORTODONTIK CEKAT TEKNIK BEGG TERHADAP BENTUK DAN LEBAR LENGKUNG GIGI BERDASARKAN TITIK PENGUKURAN WALA RIDGE (Kajian Studi Model pada Kasus Maloklusi Angle Kelas I)

Abstract

Fixed orthodontic with Begg technique uses archwire which made based on the chart that has a curved shaped with size variation. The choice of the chart  based on the sum of mesiodistal width of 6 anterior teeth of upper and lower arch. The purpose
of this research is to find out the influence of the using of archwire in fixed orthodontic treatment with Begg technique towards the shape and the width of teeth arch based on WALA ridge measurement points.
The research was done on 41 patient study models before and after treatment. The teeth arch shape was made through facial axis point of upper and lower teeth, which then was superimposed with the template of pentamorphic teeth arch shape, the
data then were  analysed using non parametric crosstabs. The teeth arch width was measured on facial axis point of inter canine and inter molar of upper and lower arch, the data then were analysed using paired t-test.
The research show that the majority of maxillary dental arch form has tapered and normal shape, while lower arch has normal shape. The width of the dental arch inter molar of upper and lower constriction. The conclusion of this research is the shape
and witdh of teeth arch after fixed orthodontic treatment using Begg technique is in accordance with the archwire used.
