Dental Arch

Dental arch

The dental arch, also called the arch of the mouth, is a soft and flexible plate that connects the teeth on either side of the jaw. It consists of periodontal tissue, the connective tissues that attach the dental arch to the walls of the skull. The arch provides a connection between two main groups of teeth - antagonists that oppose each other. There are three types of dental arch. In people who have a fully developed dental system, the dentition is positioned as the dental arch passes through the base of the tongue, which creates enough free space on the arch for the emergence and development of all teeth. These other arches can vary in shape and size. The most common type of dental arch is the fan arch. Primary teeth develop on a wider arch called the primary arch, while permanent teeth develop on a narrower arch or oscillating arch. This type of dental arch is found in most healthy people. If it is missing, the baby tooth is replaced by a tenon tooth, which is part of this type of arch. On the lower limb there is an additional part of the arc - Harmann's ring. It provides additional surface area for the gums. This is common among peoples living in parts of the world where hypothermia occurs frequently. This link is provided for illustrative purposes only.
