Reasons for Jaw Bone Loss and Deterioration

The following are the most common causes for jaw bone deterioration and loss that may require a injerto de hueso procedimiento:

Extracciones de dientes

Cuando un adulto diente se retira y no sustituye, jaw bone deterioration may occur. Los dientes naturales están incrustados en el hueso de la mandíbula y estimulan el hueso de la mandíbula a través de actividades como masticar y morder.. Cuando faltan dientes, el hueso alveolar, or the portion of the jaw bone that anchors the teeth in the mouth, no longer receives the necessary stimulation and begins to break down, o reabsorben. The body no longer uses orneeds” el hueso de la mandíbula, por lo que se deteriora y desaparece.

The rate that the bone deteriorates, as well as the amount of bone loss that occurs, varies greatly among individuals. sin embargo, most loss occurs within the first eighteen months following the extraction and will continue gradually throughout your life.

Enfermedad periodontal

Enfermedades periodontales son infecciones continua de las encías que destruyen poco a poco el apoyo de los dientes naturales. La enfermedad periodontal afecta a uno o más de los tejidos periodontales: hueso alveolar, ligamento periodontal, cemento radicular, o encía. While there are many diseases that affect the tooth-supporting structures, plaque-induced inflammatory lesions make up the majority of periodontal issues and are divided into two categories: gingivitis y periodontitis. Mientras que la gingivitis, la menos grave de las enfermedades, nunca puede progresar a periodontitis, siempre precede a la periodontitis.

Placa dental es la principal causa de la gingivitis en individuos genéticamente susceptibles. Placa es una película incolora pegajosa, compuesto principalmente de partículas de comida y varios tipos de bacterias, that adheres to your teeth at and below the gum line. La placa se forma constantemente en los dientes, incluso minutos después de la limpieza. Bacteria found in plaque produces toxins, o venenos, that irritate the gums. Pueden inflamar las encías, rojo, swollen, y sangran con facilidad. Si esta irritación se prolonga, the gums will separate from the teeth causing pockets (espacios) para formar. Si se descuida el cepillado diario y la seda dental, plaque can harden into a rough, sustancia porosa conocida como cálculo (o Tártaro). Esto puede ocurrir tanto por encima como por debajo de la línea de las encías.

Periodontitis is affected by bacteria that adheres to the tooth’s surface, junto con una respuesta inmunitaria excesivamente agresiva a estas bacterias. Si la gingivitis progresa a periodontitis, the supporting gum tissue and bone that hold teeth in place deteriorates. La pérdida progresiva de este hueso, la alveolar, can lead to the loosening and subsequent loss of teeth.


Unanchored dentures are placed on top of the gum line, but they do not provide any direct stimulation to the underlying alveolar bone. Over time the lack of stimulation causes the bone to resorb and deteriorate. Because this type of denture relies on the bone to hold them in place, people often experience loosening of their dentures and problems eating and speaking. Finalmente, bone loss may become so severe that dentures cannot be held in place with strong adhesives, and a new set of dentures may be required. Proper denture care, repair, and refitting are essential to maintaining oral health.

Some dentures are supported by anchors, which do help adequately stimulate, and therefore preserve bone.

With bridgework, the teeth on either side of the appliance provide sufficient stimulation to the bone, but the portion of the bridge that spans the gap where the teeth are missing receives no direct stimulation. Bone loss can occur in this area.

By completing a bone graft procedure, Dr. Paredes is now able to restore bone function and growth, thereby halting the effects of poor denture care.

Trauma facial

When a tooth is knocked out or broken to the extent that no biting surface is left below the gum line, bone stimulation stops, which results in jaw bone loss. Algunas formas comunes de dientes y la mandíbula trauma incluyen: teeth knocked out from injury or accident, jaw fractures, or teeth with a history of trauma that may die and lead to bone loss years after the initial trauma.

A bone grafting procedure would be necessary to reverse the effects of bone deterioration, restoring function and promoting new bone growth in traumatized areas.


Misalignment issues can create a situation in the mouth where some teeth no longer have an opposing tooth structure. The unopposed tooth can over-erupt, causing deterioration of the underlying bone.

Issues such as TMJ problems, normal wear-and-tear, and lack of treatment can also create abnormal physical forces that interfere with the teeth’s ability to grind and chew properly. Con el tiempo, bone deterioration can occur where the bone is losing stimulation.


Osteomyelitis is a type of bacterial infection in the bone and bone marrow of the jaw. This infection leads to inflammation, which can cause a reduction of blood supply to the bone. Treatment for osteomyelitis generally requires antibiotics and the removal of the affected bone. A bone graft procedure may be required to restore bone function and growth lost during removal.


Benign facial tumors, though generally non-threatening, may grow large and require the removal of a portion of the jaw. Malignant mouth tumors almost always spread into the jaw, requiring the removal of the affected section of the jaw. In both cases, reconstructive bone grafting is usually required to help restore normal function to the jaw. Grafting in patients with malignant tumors may be more challenging because treatment of the cancerous tumor generally requires removal of the surrounding soft tissues as well.

Developmental Deformities

Some conditions or syndromes are characterized by missing portions of the teeth, facial bones, jaw or skull. Dr. Las paredes pueden ser capaces de realizar un procedimiento de injerto de hueso para restaurar la función y el crecimiento óseo en el que puede estar ausente.

Sinus Deficiencies

When molars are removed from the upper jaw, air pressure from the air cavity in the maxilla (maxillary sinus) causes resorption of the bone that formerly helped keep the teeth in place. Como un resultado, the sinuses become enlarged, a condition called hyperpneumatized sinus.

This condition usually develops over several years and may result in insufficient bone from the placement of dental implants. Dr. Las paredes pueden realizar un procedimiento llamado “elevación de seno” that can treat enlarged sinuses.
