Orthodontic Extrusion of High Risk Impacted Mandibular Third Molar

Not Applicable

Completed

• Conditions: Inferior Alveolar Nerve Injuries
• Interventions: Procedure: Orthodontic extrusion of the impacted mandibular third molar by using the maxillary miniscrew and cross arch elastic power chain as a temporary anchorage device before extraction

• Registration Number: NCT06538688
• Lead Sponsor: Alexandria University

Brief Summary

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

Detailed Description

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.

Arm && Interventions

Group	Intervention	Description
Participants	Orthodontic extrusion of the impacted mandibular third molar by using the maxillary miniscrew and cross arch elastic power chain as a temporary anchorage device before extraction	Patients with impacted mandibular third molar in close proximity to the inferior alveolar nerve

Primary Outcome Measures

Name	Time	Method
Radiographically	6months	By measuring the amount of extrusion of the impacted tooth gained in millimetres Using CBCT

Secondary Outcome Measures

Name	Time	Method
clinical brush stroke directional test	6months	using a micro brush tip which was moved in horizontal and/or vertical directions on the chin area ten times and asked the patient to reproduce the movements the scale ranged from 0-2, where 0= no sensation, 1= decreased sensation and 2= normal sensation.
Clinical neurosensory assessment	6months	By using pinprick test in which ;A sharp dental probe was applied to the skin over chin region, lip and mucosa in a quick pricking movement and pain perception of the patient was assessed. Each area was tested three times bilaterally.the scale ranged from 0-2, where 0= no sensation, 1= decreased sensation and 2= normal sensation.
Clinical Two-point discrimination test	6months	By using probes of caliper device which were drawn across the skin at constant pressure and patient was asked whether one or two points were felt, the minimum separation distance was felt by the patient was termed two point discrimination threshold.scoring from 0-2 in which; 0=\>15mm, 1=8-15, 2= \<8 .
