Mandibular Arch
The mandibular arch refers to the curved structure formed by the lower jawbone, known as the mandible. It plays a crucial role in the human skull, providing support for the lower teeth and facilitating movements necessary for chewing and speaking. The shape of the mandibular arch can vary among individuals, influencing dental alignment and overall oral health.
In dental anatomy, the mandibular arch is often contrasted with the maxillary arch, which is the upper jaw. Both arches work together to enable proper occlusion, or the alignment of teeth when the mouth is closed. Understanding the mandibular arch is essential for orthodontics and dental treatments.
