Orthodontic Extrusion of High Risk Impacted Mandibular Third Molar

Alexandria University9 enrolled

Overview

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.

Outcomes

Primary Outcomes

Radiographically

By measuring the amount of extrusion of the impacted tooth gained in millimetres Using CBCT

Time frame: 6months

Secondary Outcomes

Clinical neurosensory assessment

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.

Time frame: 6months

clinical brush stroke directional test

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.

Time frame: 6months

Clinical Two-point discrimination test

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 .

Time frame: 6months
