Every orthodontic patient has a unique combination of irregularities, which makes it impossible to standardise orthodontic treatment to the point where we could tell what a patient needs from an examination alone. Orthodontic analysis involves measuring the angles and relationships of the jaws and teeth on X-rays, and measuring the deviations of the teeth on orthodontic models in the three main planes. All this information, interpreted through the orthodontist's training and experience, gives us the treatment plan. It's a step that can't be skipped.
This answer is for general information. Your own case needs an examination by an orthodontist.
