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.
Impacted wisdom teeth are classified by their direction of impaction, their depth compared to the biting surface of adjacent teeth and the amount of the tooth's crown that extends through gum tissue or bone. Impacted wisdom teeth can also be classified by the presence or absence of symptoms and disease. Screening for the presence of wisdom ...
Malocclusion is a common finding, [22] [23] although it is not usually serious enough to require treatment. Those who have more severe malocclusions, which present as a part of craniofacial anomalies, may require orthodontic and sometimes surgical treatment (orthognathic surgery) to correct the problem.
Because impacted teeth do not erupt, they are retained throughout the individual's lifetime unless extracted or exposed surgically. Teeth may become impacted because of adjacent teeth, dense overlying bone, excessive soft tissue or a genetic abnormality. Most often, the cause of impaction is inadequate arch length and space in which to erupt.
The odontogenic myxoma is an uncommon benign odontogenic tumor arising from embryonic connective tissue associated with tooth formation. [1] As a myxoma , this tumor consists mainly of spindle shaped cells and scattered collagen fibers distributed through a loose, mucoid material.
Based on the condition of your current teeth and bone or gum health, the dentist will go over the choices you have, and how closely they can meet your expectations. This is because they have to go ...
Typically the tooth is lifted using an elevator, and using dental forceps, specific tooth movements are performed (e.g. rocking the tooth back and forth) expanding the tooth socket. Once the periodontal ligament is broken and the supporting alveolar bone has been adequately widened the tooth can be removed.
If a tooth is avulsed, make sure it is a permanent tooth (primary teeth should not be replanted, and instead the injury site should be cleaned to allow the adult tooth to begin to erupt). Reassure the patient and keep them calm. If the tooth can be found, pick it up by the crown (the white part). Avoid touching the root part.
