Orthodontic treatment in the mixed dentition.

In the mixed dentition, the goal of orthodontic treatment is to maintain or improve arch integrity for the eruption of the permanent teeth, and to prevent the development of a more complicated malocclusion. The importance of correct diagnosis prior to the treatment of mixed-dentition patients cannot be over emphasized. An understanding of the mixed dentition's normal development allows clinicians to determine if the occlusion is developing outside of the normal range. Appropriate treatment can only be planned after this determination has been made. Once it is concluded that orthodontic treatment is required, decisions must be made regarding the timing of treatment, the specific type of treatment needed, and the provider of treatment. By employing a systematic approach to examination and treatment planning, the general dental practitioner can provide an important service to patients with a mixed dentition.
