Les dysmorphoses dento-maxillo faciales de la population d'Afalou-Bou-Rhummel

摘要

Summary. The systematic research of the dento-maxillo-facial malocclusions, on the Afalou Bou Rhummel population allowed to display, on the par with the alveodental complex and with basis bones, the same types of dyomorphosis that we find to day in an orthodontic service. The dento-maxilar balance with regard to the facial solid mass has been determinated owing to the cephalometric analysis (Downs, Tweed). This balance is very near of the white races' balances, but is very different of the black, Japanese, Chinese and australian arboriginal races'.
