Research Abstract

Occlusal area and bite force and occlusal force were measured by using Dental prescale of the adult who extracted at random and the jaw deformity patient before operation, and the state of the occlusion was examined.
1.On the average in the adult who extracted at random as a standard state of the occlusion.occuusal area were 11.2mm^2, maximum bite force were 102.7Mpa, average bite force were 46.5Mpa and occulusal force were 506.6N.
2.In progenia and facial asymmetry by the contact side product's at the occlusion lingua decreasing an enough occlusal strength is imagined being not able to be demonstrated
3.In retrogenia, the biting strength is imagined come in contact comparatively excellent being admitted in a custom occlusion and being demonstrated enough. However, when operating by the one of being about to see, this occlusal position should note.
