An ectopic tooth, also known as an impacted tooth, is a tooth that develops in an abnormal position and fails to erupt into its normal location in the oral cavity. [1] [2] Ectopic teeth can cause a variety of symptoms, such as pain, swelling, and infection, and they can lead to more serious complications if left untreated.
Other impacted teeth, especially canines or incisors, can be aligned with the rest of the dental arch by orthodontic treatment, thus regaining and retaining their mechanical and aesthetic function. In some cases, impacted teeth can be let sleeping inside the alveolus, but periodical check-ups are required for a possible pathological development.
Advocates of the policy point out that the impacted wisdom teeth can be monitored and avoidance of surgery also means avoidance of the recovery, risks, complications and costs associated with it. Following implementation of the NICE guidelines the UK saw a decrease in the number of impacted third molar operations between 2000 and 2006 and a ...
Severe gum disease, which may affect the supporting tissues and bone structures of teeth. Treatment of symptomatic impacted wisdom teeth e.g. that are associated with pericoronitis, unrestorable caries or cysts. [8] Prophylactic removal of asymptomatic impacted wisdom teeth.
A treatment controversy exists about the necessity and timing of the removal of asymptomatic, disease-free impacted wisdom teeth which prevents pericoronitis. Proponents of early extraction cite the cumulative risk for extraction over time, the high probability that wisdom teeth will eventually decay or develop gum disease and costs of ...
The teeth should all fit on a line of occlusion which, in the upper arch, is a smooth curve through the central fossae of the posterior teeth and cingulum of the canines and incisors, and in the lower arch, is a smooth curve through the buccal cusps of the posterior teeth and incisal edges of the anterior teeth.
When extracting lower wisdom teeth, coronectomy is a treatment option involving removing the crown of the lower wisdom tooth, whilst keeping the roots in place in healthy patients. This option is given to patients as an alternative to extraction when the wisdom teeth are in close association with the inferior alveolar nerve , and so used to ...
Common complications are pulpal necrosis, pulpal obliteration, root resorption and damage to the successors teeth in primary teeth dental trauma. The most common complication was pulp necrosis (34.2%). 50% of the tooth that have trauma related to avulsion experienced ankylotic root resorption after a median TIC (time elapsed between the ...
