To evaluate the merits of two-stage treatment for Class I and Class II malocclusions, three of the presumed benefits of this strategy – 1) improvement in self-concept, 2) greater ability to modify growth, and 3) higher quality – were assessed by reviewing the available evidence related to the ability of two-stage treatment to produce these benefits. Neither self-concept nor the ability to modify growth is improved by stage-one treatment, also, there are no skeletodental differences between the results obtained by one-stage and two-stage treatments. Accordingly, two-stage treatment cannot be endorsed on the basis of providing unique and characteristic psychological or skeletodental benefits. |
