There are two main theories on the aetiology of palatally impacted canines. One is the genetic theory whereby the cause is thought to be polygenic. There is a high rate of incidence of ectopic canines with dental anomalies such as pegged lateral incisors, missing lateral incisors, delayed eruption, and the absence of crowding.
Mandibular third molars are more commonly impacted than their maxillary counterparts. Some dentists believe that impacted teeth should be removed [1] This is often true for third molars causing various problems like pericoronitis, resorption of adjacent second molar etc. Other impacted teeth, especially canines or incisors, can be aligned with ...
Regezi and Sciubba [6] stated that the impacted teeth were most commonly seen in the third molar and maxillary canine teeth, and hence dentigerous cysts occur most frequently in these teeth. The involved teeth may be displaced into ectopic positions. In the maxilla, these teeth are often displaced into the maxillary sinus. [12]
Surgical extraction of an impacted molar. Growing state of patient is one of the factors when deciding what treatment is going to be used. For growing patients, decoronation is used. Decoronation is the removal of tooth crown. [5] It serves as an alternative surgery for tooth extraction.
Caldwell-Luc surgery, Caldwell-Luc operation, also known as Caldwell-Luc antrostomy, and Radical antrostomy, is an operation to remove irreversibly damaged mucosa of the maxillary sinus. It is done when maxillary sinusitis is not cured by medication or other non-invasive technique. The approach is mainly from the anterior wall of the maxilla bone.
Sometimes molars are distalized to make space for other impacted teeth, such as premolars or canines, in the mouth. [ 2 ] Distalization in the maxillary arch is easier than the mandibular arch because maxillary bone has more trabecular bone than the mandible, which has higher percentage of cortical bone.
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.
An oroantral fistula (OAF) is an epithelialized oroantral communication (OAC), which refers to an abnormal connection between the oral cavity and the antrum. [1] The creation of an OAC is most commonly due to the extraction of a maxillary tooth (typically a maxillary first molar) which is closely related to the antral floor.
