Artificial Teeth Are Prosthetics Made To Replace Missing Teeth.
An impacted tooth is one that fails to erupt into the dental arch within the expected developmental window. 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. That is the total length of the alveolar arch is smaller than the tooth arch (the combined mesiodistal width of each tooth). The wisdom teeth (third molars) are frequently impacted because they are the last teeth to erupt in the oral cavity. Mandibular third molars are more commonly impacted than their maxillary counterparts.
A dental restoration or dental filling is a treatment to restore the function, integrity, and morphology of missing tooth structure resulting from caries or external trauma as well as to the replacement of such structure supported by dental implants.
Impaction Impacted Tooth Extraction
"Coronectomy is a procedure where the crown of the impacted wisdom tooth is removed, but the roots are intentionally left in place. It is indicated when there is no disease of the dental pulp or infection around the crown of the tooth, and there is a high risk of inferior alveolar nerve injury."
