What causes overeruption of teeth?

Overeruption occurs when a tooth pushes out of the bone beyond the other teeth in that jaw. This leads to overeruption, an uneven bite and misalignment of the neighboring teeth. Overeruption usually occurs following a tooth extraction, in the event that the removed tooth is not replaced.

What are the functions of posterior teeth?

Molars – The most posterior teeth in the mouth are the molars. They have broader and flatter surfaces with 4-5 cusps. They are designed to grind food.

What does posterior mean in dental?

The American Dental Association (ADA) defines “posterior” as referring to the teeth and tissues toward the back of the mouth. These teeth include the premolars and molars. Unlike your front teeth‚ also known as anterior teeth‚ people won’t usually see the teeth in the back of your mouth when you smile.

What is posterior teeth Disclusion?

This is called “posterior disclusion”. Separation of the posterior teeth should occur, whether the jaw moves forward or left or right from centric relation. The reason that posterior disclusion is such a desired effect is because the moment the posterior teeth separate, almost all of the elevator muscles shut off.

What causes overeruption in unopposed posterior teeth?

Changes in patterns of tooth loss, and an ageing population, may mean that there will be an increase in the number of partially dentate patients. The type and extent of occlusal change may compromise restoration of the unopposed tooth and teeth bounding the extraction site. Strategies to prevent undesirable tooth movements may be indicated.

What is the average overeruption of a tooth?

Restorative dentists regularly see what is sometimes a dramatic loss of interocclusal space following an extraction of an opposing tooth. In their 2000 study Kiliaridis et al. 1 identified that overeruption greater than 2 mm occurs in 24% of unopposed teeth, with 18% having no demonstrable overeruption at all.

When to correct over-eruption following tooth wear spear?

If the wear is isolated to the anterior teeth, correcting the eruption will create the space needed for the restoration, and will not require any alterations to the posterior teeth. The same holds true for wear on the posterior teeth.

When does overeruption occur after loss of an antagonist?

No vertical change in tooth position occurs following the loss of an antagonist in posterior teeth. Unopposed posterior teeth are not associated with occlusal interferences. There is no association between the presence of an occlusal interference and the presence of overeruption in unopposed posterior teeth.
