To the lay person the name Maxillo Facial Orthopaedics can be very confusing. In simple terms it means changing the size, shape and relationship of the bones of the face and jaws. In most cases this correction can be accomplished using removable orthopaedic appliances as opposed to surgery. The more discerning and critical orthodontic and dental practitioner soon began to realise that most people with crooked teeth had a problem more complex than just a case of too many teeth, or teeth too big for their jaws. Research has shown that in more than 75% of cases of malocclusions the underlying problem is originally caused by a growth related problem affecting an imbalance in the relationship of the lower jaw, upper jaw and the rest of the face.
