Crowding represents one of the most frequent perhaps the main complaints of patients seeking orthodontists Fig 1. What are the factors that lead them to this situation?
The dental concrescence corresponds to the union of mature and erupted teeth by cement, which is very rare.
And the cases of people who naturally, during life time, do not show mandibular anterior crowding?
A quantitative approach for measuring crowding in the dental arch: Is mandibular anterior crowding normal or pathological? Chewing promotes occlusal wear, compensated at the tooth by the continuous deposition of apical cementum, in a process known as passive and continuous dental eruption. An interdisciplinary approach for improved functional and esthetic results deental a periodontally compromised adult patient.
Assessment of the oral health status of school children in Addis Ababa. The concept of tensegrity was established by Richard Buckminster Fuller5 an American genius who is considered a designer, an architect and a visionary writer.
In crowded teeth, dsntal 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. Stability and relapse of mandibular deental alignment: Likewise, in cases of crowded teeth dangerously close to each other, there is no root resorption neither concrescence.
Mandibular anterior crowding: normal or pathological?
Tensegrity represents the demtal of a system of forces, in which they cancel each other and the resultant will be zero. Every patient, throughout life, will have mandibular anterior crowding, as suggested by the vast majority of orthodontists and the classical orthodontic books?

Thus, resorption of the hard tissues occurs only on the bone surface of the periodontal ligament and is not visualized on its cementum surface.
Long-term comparison of extraction and nonextraction alternatives in matched apinhmaento of African American patients Am J Orthod ; Nat Rev Mol Cell Biol.
The countless mitosis, cellular movements and the constant deposition of tissue matrix generate forces that add up and increase, while making opposition to other forces from other areas.
Int J Periodontics Restorative Dent. Ustrell, Josep Duran Von Arx. Intraarch and interarch relationships of the anterior teeth and periodontal conditions. Why do teeth become so close to each other, move from their original position in the arch, but do not contact each other, even on severe cases of crowding Fig 1?

Should they really be permanently used for lifetime? Extraction decision and identification of treatment predictors in Class I malocclusions.
Rev Ateneo Argent Odontol. The architecture of life. The object or organ will thus remain in a stable shape, just like the bone as well. Late lower arch crowding in relation to skeletal and dental morphology and growth changes. Any structure that returns to its original format after each applied force is in structural and functional balance.
There are still some sental acting in search of a tensegrity that was not obtained or was lost.
As new layers of cement slowly build up, the periodontal thickness is apinbamento. In this bone remodeling, the periodontal space remains stable, thanks to the EGF that is continuously liberated by the epithelial rests of Malassez.
It should be identified which of the stability factors, or tensegrity, in the dental arch are failing or absent. The crowding can be classified as primary, secondary or tertiary, when it affects the mixed dentition in the first transitional period, second transitional period and permanent dentition, respectively. Interproximal contact points gradually turns into contact facets between the teeth, reducing the mesiodistal width between them as well as the total dental arch perimeter.
