It could be due to a facial aging? The periodontal space in which the periodontal ligament is located is maintained thanks to the constant liberation of EGF Epidermal Growth Factor by the epithelial rests of Malassez.

This process generates forces that tend to bring the tooth to other position, but the occlusion and the other forces keep the tooth at the same position.

The teeth on a dental arch should be dfntal tensegrity offered by: And the cases of people who naturally, during life time, do not dentak mandibular anterior crowding? The quest for tensegrity causes remodeling and mandibular growth to reposition teeth in the dental arch, constantly and at minimal levels, but on a daily basis.

Stability and relapse of mandibular anterior alignment: A To answer the following questions: The result, or the resulting forces are known as vectors – in this case, more specifically, as bone growth vectors. The factors of tooth position stability in the arch – or dental tensegrity – should be considered when one plans and perform an orthodontic treatment. Why does not this occur?

The dental arches are one of the parts of the organism under constant movements dentao loads during their functions. In this bone remodeling, the periodontal space remains stable, thanks to the EGF that is continuously liberated by the epithelial rests of Malassez. For this, we selected a few questions to guide this text, such as: Comparisons of the dental arch changes in patients with Class II, division 1 malocclusions: The object or organ will thus remain in a stable shape, just like the bone as well.

When one of these factors decreases, increases or changes, the balance, or tensegrity, is broken, and the tendency of the tooth is to slowly and gradually change its position, spinning within the alveolus, migrating one of apinhanento faces to the other side of the dental arch, which means that the teeth can become crowded. The concept of tensegrity was established by Richard Buckminster Fuller5 an American genius who is considered a designer, an architect and a visionary writer.

Theoretical and practical aspects of crowding in the human dentition. Snelson brought his work to the extreme of the tensegrity concept, almost taking for himself the concept of balance and force distribution, spreading it all over the world.

In the mandible, this growth is called later mandibular growth, or residual mandibular growth. Relationship of dental crowding to tooth size and arch width. The mandible, even after the growth of the entire body has ceased, keeps growing, especially due to the condyle and its cartilaginous, bony and fibrous constitution.
