Dental arch

Dental Arch

The dental arch is a term used in dentistry to describe the curved structure formed by the teeth in their normal position, or the position they are meant to occupy. The dental arch is divided into two sections: the upper dental arch and the lower dental arch, also known as the maxillary arch and the mandibular arch, respectively.

Structure

The dental arch is not a perfect semi-circle but rather a horseshoe-shaped arch. The arch is wider at the front and narrows towards the back. The teeth are arranged along the arch in a specific order: incisors, canines, premolars, and molars.

Function

The primary function of the dental arch is to support the teeth and provide a structure for them to grow into. The shape and size of the dental arch can significantly influence the alignment of the teeth, the development of the jaw, and the overall facial structure.

Clinical Significance

In orthodontics, the shape and size of the dental arch are important factors in determining the need for orthodontic treatment. Abnormalities in the dental arch can lead to various dental problems such as malocclusion, crowding of teeth, and spacing of teeth.
