| Summary: | Malocclusion is abnormal dental alignment that causes change on dental
arch dimensions. Therefore, it influences the form of dental arch. Dental arch
form is an important component to diagnose and plan orthodontic treatment. The
aim of this study was to investigate the relation between the degree of
malocclusion and maxillary arch form of Javanese people.
Fourty five study models of Orthodonsia practicum III Faculty of
Dentistry Universitas Gadjah Mada (2013) with these criteria: 1) third generation
of Javanese consist of men and women, 2) aged 19 � 25 years old, 3) complete
permanent teeth up to second molar with the Angle�s Class I first molar relation,
3) crowding, 4) no caries in cups and interproximal area, 5) Not or never been in
an orthodontic and orthognatic treatment. Study model�s degree of malocclusion
was measured by Occlusal Feature Index and the results were categorized as mild,
moderate or severe. The maxillary arch form was defined by measuring the
intercaninus width and depth. The results� ratios then were categorized as tapered,
square or ovoid. Next, the result scores of malocclusion and the ratios of arch
form were analyzed by using Pearson correlation.
The result showed there was a negative relation between the degree of
malocclusion and maxillary dental arch form of Javanese people with correlation
significancy -0,552 (p<0,05). The conclusion was the bigger of the malocclusion
scores, the smaller ratios between intercaninus width and depth. It means that the
maxillary arch form tends to be tappered. The most common of the arch form was
ovoid, followed by square, then tapered. |
