|February 11, 2026
Resumen
La tomografía computarizada de haz de cono (CBCT) puede evaluar los cambios en la densidad mineral ósea (DMO) en el hueso alveolar adolescente después del tratamiento de ortodoncia. El aumento de la DMO sugiere que el crecimiento y la mineralización contribuyen a los resultados del tratamiento.
Área de la Ciencia:
- Odontología Odontología.
- La ortodoncia es la ortodoncia.
- Radiología Radiología.
Sus antecedentes:
- Los cambios en el hueso alveolar (AB) son resultados críticos en el tratamiento de ortodoncia.
- La evaluación de la distribución tridimensional de la densidad mineral ósea (DMO) en AB es importante para los pacientes adolescentes.
Objetivo del estudio:
- Para evaluar si las imágenes clínicas de tomografía computarizada de haz de cono (CBCT) pueden evaluar los cambios en la distribución 3D de DMO en el hueso alveolar.
- Para reflejar los resultados biológicos del tratamiento de ortodoncia en pacientes adolescentes.
Principales métodos:
- Análisis retrospectivo de las exploraciones CBCT de 40 pacientes adolescentes antes y después del tratamiento de ortodoncia.
- Aislamiento digital del hueso alveolar y gráfico de frecuencia de los valores grises para la evaluación de la DMO.
- Comparación de los parámetros AB y los valores de gris vertebral cervical antes y después del tratamiento.
Principales resultados:
- Se observaron aumentos significativos en los valores grises del hueso alveolar y las vértebras cervicales después del tratamiento ortodóncico (P < .02).
- Se encontraron relaciones lineales positivas débiles entre los cambios en AB y los parámetros vertebrales cervicales (0,12 < r2 < 0,48, P < 0,04).
Conclusiones:
- El crecimiento adolescente y la mineralización ósea contribuyen al aumento de la DMO ósea alveolar después del tratamiento ortodóncico.
- Los hallazgos ofrecen datos básicos para la planificación personalizada del tratamiento de ortodoncia en adolescentes.

Essential Minerals for Bone Health
6.6K
The minerals contained in all of the food we consume are essential for our organ systems. However, certain essential minerals, such as calcium, phosphorus, magnesium, manganese, and fluoride, largely affect bone health.
Calcium and Phosphorus
Calcium is a critical component of bones, especially in the form of calcium phosphate and calcium carbonate. Since the body cannot make calcium, it must be obtained from the diet. However, calcium cannot be absorbed from the small intestine without...

Bone Structure
51.9K
Within the skeletal system, the structure of a bone, or osseous tissue, can be exemplified in a long bone, like the femur, where there are two types of osseous tissue: cortical and cancellous.

Bone Remodeling
40.5K
Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.

Compact Bone
16.8K
Most bones contain compact and spongy osseous tissue, but their distribution and concentration vary based on the bone's overall function.
Compact bone, also called cortical bone, is the denser, stronger of the two types of bone tissue. It is found under the periosteum and in the diaphyses of long bones, where it provides support and protection. The microscopic structural unit of compact bone is called an osteon, or haversian system. Each osteon is composed of concentric rings of calcified...

Bone Disorders
5.5K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

The Hyoid Bone
5.3K
The hyoid bone is a small U-shaped bone located in the upper neck at the level of the inferior mandible, with its tips pointing posteriorly. It does not directly articulate with any other bone in the body. The hyoid acts as the attachment site for the tongue, the larynx, and the pharynx. It is held in position by a series of small muscles attached from above or below. These muscles help to move the hyoid up/down or forward/back in coordination with movements of the tongue, larynx, and pharynx...
