The occluding relation: 1.Central occlusion: In central occlusion, the line between upper and lower central incisors should be in the same sagittal plane; upper teeth exceed the outer space of the lower teeth; upper teeth overlap the lower teeth within one third of labial height; the horizontal distance between upper and lower teeth is less than 3mm. 2.Counter bite : the lower teeth exceed the outer space of the upper teeth. 3.Edge to edge bite : the upper and lower teeth incisal edge is touched 4.Open bite : the upper and lower teeth are partly a parting 5.Deep over bite :the upper teeth exceed the outer space of the lower teeth; upper teeth overlap the lower teeth more than one third of labial height; the horizontal distance between upper and lower teeth is more than 3mm
