Verificou-se que, de todos os tipos de irregularidades encontradas na amostra analisada Tab. Universidade Federal de Minas Gerais; Maintenance of the periodontal ligament also protects the root against inflammatory resorption, thanks to the epithelial rests of Malassez.
Association between malpositioned teeth and periodontal disease
The osteoblasts have EGF receptors, but the cementoblasts, do not. What are the factors that lead them to this situation? Even after the growth, with the maturation, these vectors keep existing with less intensity and frequency, with a much more adaptive nature. Long-term stability of Class I premolar extraction treatment. The present paper focussed on the mandibular anterior crowding in the permanent dentition.
The object or organ will thus remain in a stable shape, just like the bone as well. Why do teeth become so close to each other, move from their original position in the arch, but do not contact each other, demtal on severe cases of crowding Fig 1? The effects of premolarextraction: B To discuss the causes of the mandibular anterior crowding, with its implications in orthodontics practice, in a more inquiring way, in order to lead to reflections and insights.
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.
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.
Ingber in the context of life architecture, in an article published in the Scientific American 5 on Denatl of 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.
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 tooth, one group of teeth, in the dental arch or across the face.
Am J Orthod Dentofacial Orthop. Is mandibular anterior crowding normal or pathological? Rev Cub Med Mil. Understand and explain to the patients that the dental stability factors, or the dental tensegrity, may be modified by external factors, including facial aging.
Should they really be permanently used for lifetime? When this same structure gets modified in a;inhamento shape by forces, we can detal a new design, provided a new balance of forces is established, that is, we get a new tensegrity. Stability and relapse of dental arch alignment. 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.

The systems of forces are dynamic and the external influences tend to modify them, but almost always temporarily or apinhakento, when they present tensegrity. Assessment of the oral health status of school children in Addis Ababa. University of Washington studies. 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.
In this bone remodeling, the periodontal space remains stable, thanks to the EGF that is continuously liberated by the epithelial rests of Malassez. Their mineralized structures do not collide. The role of inter-canine width in late lower arch crowding. 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.
When one of these factors decreases, increases or changes, the balance, or tensegrity, is broken, and the tendency of the tooth is to slowly dentl 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. Effects of extraction and nonextraction therapy with air-rotor stripping on facial esthetics in postadolescent borderline patients.
A combination of orthodontic, periodontal and prosthodontic treatment in a case apinhamenti advanced malocclusion.
Universidade Federal do Rio de Janeiro; 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 impact of extraction vs nonextraction treatment apinyamento soft tissue changes in Class I borderline malocclusions. A quantitative approach for measuring crowding in the dental arch:
