Fractures: Bone Repair

6.6K
Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...

Summary

Impacted mandibular third molars increase the risk of angle fractures while decreasing the likelihood of condylar fractures, particularly when deeply seated. This finding is crucial for understanding mandibular fracture patterns.

Area of Science:

  • Oral and Maxillofacial Surgery
  • Dental Traumatology
  • Radiology

Background:

  • Mandibular fractures are common injuries.
  • The position and impaction status of the mandibular third molar are potential contributing factors to fracture patterns.

Purpose of the Study:

  • To evaluate the impact of mandibular third molar position on the occurrence of angle and condylar fractures.
  • To correlate third molar presence and impaction with specific fracture types.

Main Methods:

  • Panoramic radiographs of 64 patients with mandibular fractures were analyzed.
  • Fracture patterns were classified based on the presence, absence, or impaction of the mandibular third molar.

Main Results:

  • Condylar fractures accounted for 67% and angle fractures for 33% of cases.
  • Erupted third molars were associated with 75% of condylar fractures, while impacted teeth were linked to 25%.
  • Angle fractures were more frequent with impacted, mesioangular, or distoangular third molars, often resulting from mild force.

Conclusions:

  • Impacted mandibular third molars are associated with a higher incidence of angle fractures.
  • Deeply impacted third molars appear to reduce the risk of condylar fractures.
  • Understanding third molar positioning is vital for predicting mandibular fracture susceptibility.
