Fractures: Bone Repair01:27

Fractures: Bone Repair

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 procedure...

Summary
This summary is machine-generated.

Posterior crossbite correction using maxillary expansion shows excellent long-term stability. Early intervention is crucial to prevent skeletal changes and ensure lasting functional and aesthetic results.

Area of Science:

  • Dentistry
  • Orthodontics
  • Craniofacial Biology

Background:

  • Posterior crossbite is a malocclusion defined by inadequate transversal tooth relationships.
  • Untreated posterior crossbite can lead to irreversible skeletal changes and functional deficits.
  • Early intervention with maxillary expansion is recommended to correct this condition.

Observation:

  • This study evaluated the long-term stability of posterior crossbite correction.
  • An overcorrection expansion protocol was employed to enhance treatment stability.
  • The study aimed to demonstrate sustained results 21 years post-treatment.

Findings:

  • Maxillary expansion effectively corrected posterior crossbite.
  • The treatment resulted in improved tooth/skeletal relationships and masticatory function.
  • Excellent long-term stability of the correction was observed 21 years after treatment.

Implications:

  • Early orthodontic treatment of posterior crossbite yields stable, predictable outcomes.
  • Maxillary expansion is a viable and effective treatment for improving craniofacial relationships.
  • This research supports early intervention to prevent complex orthodontic issues and ensure long-term oral health.
