Exact assessment of craniofacial anatomy is essential for achieving exceptional results in orthodontics.
Additionally, versions in skull structure can impact physiological traits which include respiratory and chewing. As an illustration, populations with wider nasal cavities might be better suited to humid climates, though These with narrower nasal passages may adapt much better to chilly, dry environments.
