Orthodontic Extrusion of High Risk Impacted Mandibular Third Molar

Evaluation of Orthodontic Extrusion of Impacted Mandibular Third Molar in Close Proximity to Inferior Alveolar Nerve Prior to Extraction ( a Clinical Trial)

The goal of this clinical trial is to investigate the usage of maxillary miniscrew and cross-arch elastics for the orthodontic traction of the impacted mandibular third molar in close proximity to the inferior alveolar nerve to decrease the chance of nerve injury

To investigate the traction of the impacted mandibular third molar away from the inferior alveolar nerve by using the orthodontic miniscrew in the maxillary bone and cross-arch elastic power chain as a temporary anchorage device before extraction to avoid injury of the nerve and neurosensory complications.

Inclusion Criteria:

• patients with impacted mandibular third molar in close proximity to the inferior alveolar nerve.
• Cooperative patients free of chronic diseases which interfere with needed results (e.g.diseases affect the bone regeneration ).
• Patients with good oral hygiene.

Exclusion Criteria:

• patients with limitation in mouth opening.
• patients with mental or physical disabilities.
• Allergy to anaesthetic components or antibiotics.
