The maxillary and mandibular canines bear a close resemblance to each other, and their functions are closely related. The four canines are placed at the 'corners' of the mouth; each one is the third tooth from the median line, right and left, in the maxilla and mandible. They are commonly referred to as the cornerstones of the dental arches. They are the longest teeth in the mouth; the crowns are usually as long as those of the maxillary central incisors, and the single roots are longer than those of any of the other teeth. The middle labial lobes have been highly developed incisally into strong, well-formed cusps. Crowns and roots are markedly convex on most surfaces. The shapes and positions of the canines contribute to the guidance of the teeth into the intercuspal position by 'canine guidance.' The shape of the crowns—with their single pointed cusps, their locations in the mouth, and the extra anchorage furnished by the long, strongly developed roots—makes these canines resemble those of the carnivore.
Understand the Problem
The text provides a detailed description of maxillary and mandibular canines, focusing on their anatomy, function, and significance in dental health. It discusses their shape, roots, and effects on facial aesthetics, explaining why canines are important in both natural and prosthetic dental contexts.
Answer
The maxillary and mandibular canines are the longest teeth and are the 'cornerstones' of dental arches, positioned at the corners of the mouth.
The maxillary and mandibular canines are referred to as the cornerstones of the dental arches. These four teeth are positioned at the corners of the mouth and have long, strong roots, making them the longest teeth in the mouth.
Answer for screen readers
The maxillary and mandibular canines are referred to as the cornerstones of the dental arches. These four teeth are positioned at the corners of the mouth and have long, strong roots, making them the longest teeth in the mouth.
More Information
The canines are essential for biting and tearing food and also play a crucial role in guiding the alignment of other teeth when the jaws are closed.
Tips
A common mistake is to overlook the significance of the canines' roots in providing stability to the dental structure.
