The systems of forces are dynamic and the external influences tend to modify them, but almost always temporarily or fleetingly, when they present tensegrity.
Arch width after extraction and nonextraction treatment. J Am Dent Assoc. Skeletal anchorage for orthodontic correction of maxillary protrusion with adult periodontitis.
An evaluation of changes in mandibular anterior alignment from 10 to 20 years’ post retention.
Even with enough space in the dental arch, can crowding occur? Even preserving the height of the clinical crown, this process promotes changes at the occlusion, which needs to be compensated. Post dentap evaluation of stability and relapse mandibular arches with generalized spacing. The dental arches are one of the parts of the organism under constant movements and loads during their functions.
Maybe just arranging and earning space will not solve crowding. This indicates a full and perfect system of forces distribution – a balance – whose property is called tensegrity.
It could be due to a facial aging? A quantitative approach for measuring crowding in the dental arch: Accept that tensegrity obtained at the beginning was not stable, permanent and definitive.
Eur J Orthod ; If, after orthodontic treatment, retainers use is mandatory, we must consider that: The periodontal space in which the periodontal denttal is located is maintained thanks to the constant liberation of EGF Epidermal Growth Factor by the epithelial rests of Malassez. Why do not even very close teeth, like crowded teeth, evolve to concrescence?
Association between malpositioned teeth and periodontal disease
Rev Cub Med Mil. 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.
Angle Orthod ; Prevalence of malocclusion in year-old North Jordanian school children. The teeth on a dental arch should be on tensegrity offered by:. Maintenance of the periodontal ligament also protects the root against inflammatory resorption, thanks to the epithelial rests of Malassez.
It would be necessary to orthodontically correct crowding, aligning teeth and reestablishing the tensegrity in a new reality, with well positioned mandibular teeth and in a good relationship with the maxillary ones and soft tissues. This matter is not totally clarified in the literature, but a meticulous study of its evolution in time suggests that the mandibular anterior crowding represents the break of tensegrity in the dental arch. 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.
Intraarch and interarch relationships of the anterior teeth and periodontal conditions. The factors of tooth position stability in the arch – or dental tensegrity – should be considered when one plans and perform an orthodontic treatment. The word crowding is originated from the verb to crowd, which means: ABSTRACT The teeth become very close to each other when they are crowded, but their structures remain individualized denfal, in dejtal situation, the role of the epithelial rests of Malassez is fundamental to release the EGF.

Am J Orthod Dentofacial Orthop. Oral health among Liberian refugees in Ghana. 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.
Snelson brought his work to deental extreme of the tensegrity concept, almost taking for himself the concept of balance and force distribution, spreading it all over the world.
The mandibular anterior crowding in adults can be explained as a result of the change in the distance between the lower canines, although some retainers bonded to the canines may, eventually, be seen with crowding of the incisors. This would be a residual mandibular growth that would lead to a bone increase to the anterior region, with a subtle but efficient displacement of the teeth toward the midline. Diastemas in primary dentition and their relationships to sex, age and dental occlusion.
Late lower arch crowding in relation to skeletal and dental morphology and growth changes. How to cite this article. The concept of tensegrity is fundamental to understand the responses of tissues submitted to forces in body movements, including teeth and their stability in this process. Any structure that returns to its original format after each applied force is in structural and functional balance.
Crowding should be considered a loss denfal tensegrity of teeth in the dental arch, and not simply a consequence of the lack of space. What could be the reasons for this intercanine width reduction at the lower arch? In the mandible, this growth is called later mandibular growth, or residual mandibular growth.
