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 ...
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.
Ankylosis of deciduous teeth may rarely occur. The most commonly affected tooth is the mandibular (lower) second deciduous molar. Partial root resorption first occurs and then the tooth fuses to the bone. This prevents normal exfoliation of the deciduous tooth and typically causes impaction of the permanent successor tooth.
Trabecular angulation, impaction lines, and sclerotic bands also suggest fracture in osseous structures with a significant proportion of cancellous bone such as proximal femur. [ 1 ] The general rule is to perform two orthogonal views, but more specific views should be added if there is any suspicion of fracture.
A bone fracture (abbreviated FRX or Fx, F x, or #) is a medical condition in which there is a partial or complete break in the continuity of any bone in the body. In more severe cases, the bone may be broken into several fragments, known as a comminuted fracture . [ 1 ]
The rigidity may be complete or partial and may be due to inflammation of the tendinous or muscular structures outside the joint or of the tissues of the joint itself. [1] When the structures outside the joint are affected, the term "false ankylosis" has been used in contradistinction to "true ankylosis", in which the disease is within the joint.
Radiographs examinations are indicated for any retained root tips, impacted teeth, bony pathology and impacted teeth to minimise post denture insertion discomfort. The degree of maxillary sinus pneumatization, and the position of the inferior alveolar canal and mental foramina are important as well to avoid impingement of denture on these vital ...
