The standards for normal teeth occlusion should include the following:
The teeth are normal in size and shape and arranged neatly.
The occlusal relationship of the upper and lower jaw teeth was normal. The pits of the upper and lower teeth were relatively and widely contacted, and the overlap and cover were normal.
The abutment relationship of each tooth is normal, the shape, length and width of the upper and lower dental arches are appropriate, and the center lines are aligned.
The size, shape, and position of the mandible were normal.
The facial and peri-oral muscles develop and function normally.
The structure and function of the temporomandibular joint are normal.
The mandibular function is balanced when it is in motion and closed when it is closed.
The upper and lower teeth are cut in an orderly manner so that the teeth can chew normally and eat. If tooth bite deviation is too great, then oral function will be problematic.
