Distal occlusion

An enlarged frontal tooth phase (characteristic of a distal bite) applies of a sagittal distance of 5 mm or more is measured between the incisors of the upper and lower jaws in terminal occlusion. The lower jaw usually registers a posterior position (retrogenia), whereby the front of the upper jaw can be tilted either forwards or backwards. Accurate diagnosis of the skeletal situation is done by analysing a teleradiological image.
