What is alveolar resorption?

Alveolar ridge resorption following tooth extraction is an extremely common and generally inevitable side effect of removing a tooth from its socket in the alveolar ridge.

What are the cells for resorption of alveolar bone?

Two major types of cells participate in the process—osteoblasts and osteoclasts. Osteoblasts in the alveolar bone originate directly from the dental mesenchyme (intramembranous ossification).

What is ridge resorption?

Also known as residual ridge resorption, is the loss of supporting tissue (alveolar process) of the teeth. It mostly happens when the bone around the teeth is lost due to extractions or loss of teeth.

What causes alveolar resorption?

Loss of teeth results in irreversible alveolar bone resorption, and untreated dental disease causes alveolar bone lysis that ultimately leads to loss of teeth.

How do you prevent ridge resorption?

Attempts to reduce alveolar bone resorption have included the placement of natural roots, root analogues, and immediate implants into the extraction socket, sometimes in combination with membrane or graft techniques.

What does resorption mean?

Resorption is the breakdown and assimilation of old bone in the cycle of bone growth. The process of resorption (remodeling) involves the removal of hard bone tissue by osteoclasts followed by the laying down of new bone cells by osteoblasts.

Can bone resorption be reversed?

On its own, bone loss cannot be reversed. Left untreated, the bone in your jaw and around your teeth will continue to resorb, leading to more tooth loss, disease, and pain. There is good news!

What triggers bone resorption?

Bone resorption is highly stimulated or inhibited by signals from other parts of the body, depending on the demand for calcium. Calcium-sensing membrane receptors in the parathyroid gland monitor calcium levels in the extracellular fluid.

Why does residual ridge resorption occur?

Residual Ridge Resorption is a progressive, irreversible disease, as a result of multifactorial origin. Resorption occurs in the alveolar process and the basal portion remains intact. The size and density of basal portion decreases due to reduced muscular function activity.

Does vitamin D increase bone resorption?

Vitamin D-Regulated Bone Resorption In addition to its role in promoting bone formation, 1,25 (OH)2D promotes bone resorption by increasing the number and activity of osteoclasts [69].

How long does bone resorption take?

There are five phases in the bone remodeling process: ACTIVATION, RESORPTION, REVERSAL, FORMATION, and QUIESCENCE. The total process takes about 4 to 8 months, and occurs continually throughout our lives.

What happens during resorption?

The process of resorption (remodeling) involves the removal of hard bone tissue by osteoclasts followed by the laying down of new bone cells by osteoblasts. Resorption releases calcium and repairs micro-damage to bones from normal wears and tears.

What does the term residual alveolar ridge mean?

Residual Alveolar Ridge is the absence of teeth after tooth extraction and after extraction of the teeth the bone starts to resorb which is called as Residual Ridge resorption.

What are the codes for alveolar ridge defects?

not present Defect code H.1.i: Small defect up to 4 mm, inside the ridg Defect code S.1: Small defect in the sinus area lower tha external not required) Defect code C.2.e.S.1: Combined alveolar ridge defect of 4-8 mm envelope, with sinus defect < 4 mm

Which is the correct treatment for alveolar ridge split?

Here, treatment management strategies of the horizontally collapsed ridges, especially the ridge-split approach, are discussed and a clinically relevant implant-driven classification of the alveolar ridge width is proposed, with the goal to assist an operator in choosing the proper bone augmentation technique.

How did Wang and Al-Shammari classify the alveolar ridge?

In 2002, Wang and Al-Shammari 22 described a practical (therapeutically oriented) classification of alveolar ridge defects, that is, horizontal, vertical, and combination defects, proposing the edentulous ridge expansion approach (ridge-split) for the horizontal and combination defects of the alveolar ridge.
