Overeruption

Source: Wikipedia, the free encyclopedia.

In dentistry, overeruption is the physiological movement of a tooth lacking an opposing partner in the dental occlusion. Because of the lack of opposing force and the natural eruptive potential of the tooth there is a tendency for the tooth to erupt out of the line of the occlusion.

Etymology

The physiological movement of a tooth lacking an opposing partner in the dental occlusion is termed overeruption, hypereruption, supraeruption, supereruption or continuous eruption.[1]

Pathophysiology

Because of the lack of opposing force and the natural eruptive potential of the tooth there is a tendency for the tooth to erupt out of the line of the occlusion.[citation needed]

Not all teeth lacking an opposing tooth overerupt, even in long term.[2] Unopposed upper jaw molars overerupt more than the unopposed lower jaw molars.[3][4] It is more severe in young people and periodontically affected people.[5] The changes are most visible in the first year after the loss of the opposing tooth.[6]

Treatment

A systematic review on the treatment need for back jaw spaces without any teeth found that overeruption was limited to 2 mm for most studies reviewed. The authors of the review also noted the low quality of evidence and concluded that tooth replacement is not recommended as the chief therapy.[5]

Overeruption can cause interferences in the occlusion and difficulty when constructing

Overeruption is treated either by forcing the tooth back using
