Abstract
Malocclusion is said to be a factor related not only to dental caries, periodontitis, a poor mastication but also to mental health. The purpose of this study was to what influences the total masticatory system, using DENTAL PRESCALE(R) with normal and malocclusion for children. The assessment of occlusions which were divided into the normal, the cross bite, the open bite, the deep overbite, the upper protrusion, the edge to edge bite and the crowding was done by measurements using DENTAL PRESCALE®50 R.
The results were as follows,
1, The occlusal contact area and force on the upper protrusion, the anterior cross bite and the open bite groups showed significantly lower values than the normal occlusion, the deep overbite, the posterior cross bite, the edge to edge bite and the crowding groups.
2, The occlusal contact area on the normal occlusion group showed a significantly lower value than the deep overbite group, and the occlusal force showed a significantly lower value than the deep overbite and the posterior cross bite groups.
3, Maximum pressure in the open bite group showed a significantly lower value than the normal occlusion and the deep overbite groups.
4, The mean pressure of occlusion in the deep overbite group showed a significantly lower value than the normal occlusion, the crowding and the upper protrusion groups, and in the normal occlusion group showed a lower value than the upper protrusion group.
As these results suggested that the upper protrusion, the anterior cross bite and the open bite groups influenced the development of total masticatory system, it is supposed that malocclusions were improved in their early stage.
