Comparisons of the dental arch changes in patients with Class II, division 1 malocclusions: The quest for tensegrity causes remodeling and mandibular growth to reposition teeth in the dental arch, constantly and at minimal apinhamennto, but on a daily basis.
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. Rev Cub Med Mil. In this bone remodeling, the periodontal space remains stable, thanks to the EGF that is continuously liberated by the epithelial rental of Malassez.
But the system may be modified, losing its tensegrity, until a new shape and balance position is obtained, which may not be esthetic and functionally convenient, such as a crowded dental arch in the anterior region. Multidisciplinary treatment of “twinned” permanent spinhamento In the day to day of bone remodeling and reformatting, as well as in the physiology of the stomatognathic system, forces are generated that can easily break the obtained dental, bone and facial tensegrity.
Chewing promotes occlusal wear, compensated at apinhamemto tooth by the continuous deposition of apical cementum, in a process known as passive and continuous dental eruption. Even in the most severe crowding cases, the teeth do not touch one another.
Nat Rev Mol Cell Biol. The possibility of skeletal anchorage. Stability and relapse of mandibular anterior alignment: The concept of tensegrity is fundamental to understand the responses of tissues submitted to forces in body movements, including teeth and their demtal in this process. 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 its faces to the other side of the dental arch, which means that the teeth can become crowded.
An interdisciplinary approach for improved functional and esthetic results in a periodontally compromised adult patient.
Association between malpositioned teeth and periodontal disease
Many apinhammento about the mandibular anterior crowding tend to generate incomplete, evasive and reticent answers, since there are still many doubts about it, although it is a very studied subject in the literature. The factors of tooth position stability in the arch – or dental tensegrity – should be considered when one plans and perform an orthodontic treatment.
Likewise, in cases of crowded teeth dangerously close fental each other, there is no root resorption neither concrescence. ABSTRACT The teeth become very close to each other when they are crowded, but their structures remain individualized and, in this situation, the role of the epithelial rests of Malassez is fundamental to release the EGF. Thus, resorption of the hard tissues occurs only on the bone surface of the periodontal ligament and is not visualized on its cementum surface.
Tensegrity represents the balance of a system of forces, in which they cancel each other and the resultant will be zero.
Services on Demand Journal. These changes micrometrically alter teeth position, and its tensegrity is recomposed from the bone remodeling and the terminal mandibular growth.
Why does not this occur? Angle Orthod ; The teeth become very close to each other when they are crowded, but their structures remain individualized and, in this situation, the role of the epithelial rests of Malassez is fundamental to release the EGF.

If one of the six determining factors of the dental tensegrity in the dental arch fails or reduces its effectiveness on stabilization, we may have dental crowding from light to severe.
Late lower arch crowding in relation to the direction of eruption. Intraarch and interarch relationships of the anterior teeth and periodontal conditions. What could apinhamengo the reasons for this intercanine width reduction at the lower arch?
This process generates forces that tends to take the tooth to other position, but the occlusion and all the other forces keep the tooth on the same position.

The effects of premolarextraction: The dental arches are one of the parts of the organism under constant movements and loads during their functions. The primary role of functional ma-trices in facial growth. When a system receives external or internal forces and the final resultant is equal to zero, it means that there is a balance in this system, that is, it has tensegrity, which can be analyzed exclusively in one spinhamento, one group of teeth, in the dental arch or across the face.

Even preserving the height of the clinical crown, this process promotes changes at the occlusion, which needs to be compensated. Long-term stability of Class I premolar extraction treatment. Recognize that the mandibular anterior crowding is a result of tensegrity loss in the dental arch.
Prevalence of malocclusion in year-old North Jordanian school apinhament. Any fail on the tensegrity factors can lead to the mandibular anterior crowding. Control of stem cell fate by physical interactions with the extracellular matrix.
For example, the bones will be reabsorbed or undergo neoformation, vases will get larger, muscles will be sore and tense, everything to have tensegrity again, since the new shape gives back the zpinhamento and equilibrates the system. Tensegrity is the term used to describe the concept of balance or stability of any system of forces of nature or made by humans, including the dental arch.
