La thérapeutique du «Distal Active Concept» appliquée à la denture mixte : une étude comparative Volume 72, issue 4, Décembre 2001

Authors

The "Distal Active Concept" (DAC®) therapy used during the mixed dentition period shows a mandibular growth of 7,6 mm whereas the same treatment applied on the permanent dentition only shows a mandibular growth of 3,9 mm. This différence is highly significant.

The DAC® therapy is prescribed to a group of 30 nine years old patients with a mixed dentition for six months. The DAC® therapy is prescribed to a group of 34 twelve years old patients with a permanent dentition for 24 months. As the mandibular answer to treatment seems to be more effective at the age of 9 than later, during the prepubertal period, the DAC® therapy appears to be of interest and an alternative to activator treatments. Our results show the efficiency of a first stage treatment, for all the patients showing a significant class II malocclusion.
