Análisis biomecánico cráneo-cervical y su relación con maloclusiones en una población mexicana.

Objective: To find an association between the position of the head and neck and malocclusions in patients of the Universidad Autónoma de Nayarit (México) Orthodontics Specialty. Method: A descriptive, cross-sectional, retrospective and observational study was carried out, taking into account a total of 120 lateral skull radiographs. Results: In class I patients, the craniovertebral angle had an average of 102.05°, the hyoid triangle had an average of -0.63 mm, the C0-C1 distance obtained an average of 7.22 mm and the C1-C2 distance had an average of 4.95 mm. In class II patients, the craniovertebral angle presented an average of 100.02°, the hyoid triangle with -0.52 mm, the C0-C1 distance its average was 7.05 mm and the C1-C2 distance obtained an average of 5.7 mm. In class III patients, the craniovertebral angle presented an average of 101.83°, the hyoid triangle was -0.74, the C0-C1 distance averaged 7.07 mm, and the C1-C2 distance averaged 5.33 mm. Conclusions: Include biomechanical analysis of head and neck posture to obtain a more complete diagnosis. [ABSTRACT FROM AUTHOR]
