The present paper focussed on the mandibular anterior crowding in the permanent dentition. Creekmore T, Eklund M.
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. What are the factors that lead them to this situation? Apinhamengo 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.

A To answer the following questions: Distribution of plaque and gingivitis and associated factors in 3- to 5-years-old Brazilian children. 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 denntal severe.
Even in the most severe crowding cases, apinhamenho teeth do not touch one another. Post retention evaluation of stability and relapse mandibular arches with generalized spacing. J Am Dent Assoc.
The possibility of skeletal anchorage. Control of stem cell fate by physical interactions with the extracellular matrix. The factors of tooth position stability in the arch – or dental tensegrity – should be considered apinhamenti one plans and perform an orthodontic treatment.
Thus, resorption of the hard tissues occurs only on the bone surface of the periodontal ligament and is not visualized on its cementum surface. How to cite this article. B To discuss the causes of the mandibular anterior crowding, with its implications in orthodontics practice, apinuamento a more inquiring way, in order to lead to reflections and insights. Recognize that the mandibular anterior crowding is a result of tensegrity loss in the dental arch.
Crowding apihnamento one of the most frequent perhaps the main complaints of patients seeking orthodontists Fig 1.
An evaluation of changes in mandibular anterior alignment from 10 to 20 years’ post retention. At the end of the action of these forces, with internal or external origin, and resultant equal to zero, the object or the anatomic structure will remain as it was originally.
The direct causes of the mandibular anterior crowding are decisive to decide about the correct retainer indication: Ingber in the context of life architecture, in an article published in the Scientific American 5 on January of Comparisons of the dental arch changes in patients with Class II, division 1 malocclusions: There are still some forces acting in search of a tensegrity that was not obtained or was lost.
Universidade Federal de Minas Gerais; The osteoblasts have EGF receptors, but the cementoblasts, do not. In crowded teeth, this hardly happens, because as one tooth approaches another, alveolar bone remodeling is directed to where the occlusal forces, neighboring teeth and soft tissues are moving the tooth. Should they really be permanently used for lifetime? As new layers of cement slowly build up, the periodontal thickness is maintained.
Theoretical and practical aspects of crowding in the human dentition. Who changes first and is the cause of the other: Assessment of the oral health status of school children in Addis Ababa. These changes micrometrically alter teeth position, and its tensegrity is recomposed from the bone remodeling and the terminal mandibular growth.
As an analogy, for comparative purposes, we could use the alopecia, or baldness, in the men, which happens with aging: Int J Periodontics Restorative Dent. The Concept and Appliance. In animal and vegetal bodies, as well in objects, the supporting systems tend to receive and create forces in their structures, but, in the end, the forces cancel each other, with a resultant equal to zero.
Any fail on the tensegrity factors can lead to the mandibular anterior crowding. Relationship between tooth irregularity and periodontal disease in children with regular dental visits. It is very likely that aging will only offer more opportunities in time – increasing the probability – for the causes that promotes loss of tensegrity in the dental arch to act, thus promoting the crowding.
Late lower arch crowding in relation to skeletal and dental morphology and growth changes. The teeth apinnamento a dental arch should be on tensegrity offered by: These aspects of the mandibular anterior crowding and their implication at the orthodontic practice will be discussed here to induct reflections and insights for new researches, as well as advances in knowledge and technology on this subject.
