[The therapeutic impact of the Begg technic on vertical dimension]

In order to check the vertical dimension of children treated with the BEGG technique, 138 children aged 11 or 12 have been compared to the untreated children of the RIOLO, MOYERS, MAC NAMARA, HUNTER Atlas. 1. With the mesofacial children the vertical measurements increase very little under the treatment (SWAIN, ACKERMANN). 2. With half of the brachyfacial children--whose vertical measurements at the end of the traitment are lower than those of their group--the vertical measurements increase much above the average brachyfacial group. With the other half of the brachyfacial children--whose vertical measurements at the end of treatment are the highest in their group--the vertical measurements don't increase much. 3. With some of the dolichofacial children--whose vertical measurement at the end of treatment are high compared to the average dolichofacial group--the vertical measurements increase very little With other dolichofacial children--whose vertical measurements at the end of treatment are low compared to the average dolichofacial group--the vertical measurements increase with the treatment.
