It is not sufficient to categorize orthodontic malocclusions on the basis of a classification of the teeth alone. The relationship with other craniofacial structures must also be taken into consideration.
Class I
Maxillary-Mandibular Dental Protusion - teeth
This is an example of a dental malocclusion that may require the removal of teeth for correction.
Maxillary-Mandibular Dental Retrusion - teeth
This is an example of a dental malocclusion that may be treated with expansion rather than removing teeth.
