fissured fracture

fis·sured fracture (fshrd)

n.

See linear fracture.

---

fracture,

n a break or rupture of a part. In the oral region, fracture is most often seen in teeth and bones.

fracture, avulsion,

n the loss of a section of bone.

fracture, blow-out,

n a fracture involving the orbital floor, its contents, and the superior wall of the maxillary antrum, in which orbital contents are incarcerated in the fracture area, producing diplopia.

fracture, bulk,

n a fracture or failure in the amalgam of a restoration. An improperly finished restoration by the dental professional, poor cavity design, or improper loading of the restoration can lead to a bulk fracture.

fracture, cementum,

n the tearing of fragments of the cementum from the tooth root.

fracture, clasp,

n failure of a clasp arm because of stresses that have exceeded the elastic limit of the metal from which the arm was made.

fracture, closed reduction of,

n a reduction and fixation of fractured bones without making a surgical opening to the fracture site.

fracture, comminuted,

n a fracture in which the bone has several lines of fracture in the same region; a fracture in which the bone is crushed and splintered.

fracture, compound,

n a fracture in which the bony structures are exposed to an external environment.

fracture, craniofacial dysjunction (transverse facial fracture),

n a complex fracture in which the facial bones are separated from the cranial bones; a LeFort III fracture.

fracture, dislocation,

n a fracture of a bone near an articulation, with dislocation of the condyloid process.

fracture, fissured,

n a fracture that extends partially through a bone, with no displacement of the bony fragments.

fracture fixation,

n the fractured fragments of bone are stabilized in close proximation to promote healing.

fracture, greenstick,

n a fracture in which the bone appears to be bent; usually only one cortex of the bone is broken.

fracture, Guérin's

(gāraz´),
n.pr a LeFort I fracture of the facial bones in which there is a bilateral horizontal fracture of the maxillae.

fracture, impacted,

n a fracture in which one fragment is driven into another portion of the same or an adjacent bone.

fracture, indirect,

n a fracture at a point distant from the primary area of injury caused by secondary forces.

fracture, intraarticular,

n a fracture of the articular surface of the condyloid process of a bone.

fracture, intracapsular,

n a fracture of the condyle of the mandible occurring within the confines of the capsule of the temporomandibular joint.

fracture, LeFort,

n.pr a transverse fracture involving the orbital, malar, and nasal bones.

LeFort classifications.

fracture, midfacial,

n fractures of the zygomatic, maxillary, nasal, and associated bones.

fracture, pyramidal,

n a fracture of the midfacial bones, with the principal fracture lines meeting at an apex in the area of the nasion; a LeFort II fracture.

fracture, root,

n a microscopic or macroscopic cleavage of the root in any direction.

fracture, simple,

n a linear fracture that is not in communication with the exterior.

fracture, stress,

n 1. a type of stress usually occuring from sudden, strong, violent, endogenous force, such as a simple fracture of the fibula in a runner.
2. the fracture of metallic parts as a result of fatigue of prolonged or frequent stress.

Tooth fracture.

fracture, tooth,

n a traumatic injury to a tooth that manifests itself as a chip, crack, or break. Manifestations may also include dislocation or complete displacement of a tooth.

fracture toughness,

n the quality of the material used for brackets that indicates its ability to withstand applied force without cracking.

fracture, transverse facial,

n See fracture, craniofacial dysjunction.
