Abstract

The orthodontic treatment philosophy and strategy toward patients with different vertical facial pattern such as open bite or deep bite, long face or short face, are usually different. The relationship between facial morphology in vertical dimension and masticatory musculature are always interested by orthodontists. However, the cause and effect relationship between muscle function and facial morphology is still inconclusive. To get a better understanding of previous works, this article mainly reviews the relationship between function and form into three aspects: bite force, cross-sectional area of muscle, orientation and mechanical advantage of muscle.
