Transversal comparative study of mcnamara maxillofacial mandibular ratio applied in Mexican subjects [Estudio transversal comparativo de la relación maxilo-mandibular de McNamara aplicadas a sujetos Mexicanos]

The anthropological characteristics between different races in which ethnicity, sex and age vary in the world, and it becomes necessary to analyze a set for one population study that cannot be used for another, with different shapes and characteristics. There is a need for studies in different races for comparison with established standards. The objective of the research was to compare the McNamara maxilla-mandibular relationship applied in Mexicans subjects and analyze 60 lateral radiographs of the skulls with McNamara traces. Genetic differences in growth patterns of Caucasians and Mexicans were identified. Our results show typical growth of skeletal class II patients with hypotonic posterior jaw, and jaw with diminished vertical height caused by a lack of midface growth the result of poor air flow. © 2016, Universidad de la Frontera.
