Brief Summary

What is the effect of extraction orthodontic treatment in comparison to non- extraction treatment on the position, inclination and incidence of impaction of the third molars?

Conditions

Orthodontic Treatment Via Premolar Extraction

Keywords

third molar impaction, third molar angulation, third molar vertical position

Outcome Measures

Primary Outcomes (1)

• third molar angulation

  The angulation of the mandibular third molars

  at the end of orthodontic treatment

Secondary Outcomes (4)

• space available for the upper and lower third molar

  at the end of orthodontic treatment

• Angulation of the third molar.

  at the end of orthodontic treatment

• The vertical position of the third molars

  at the end of orthodontic treatment

• the mineralization status of the third molars

  at the end of orthodontic treatment

Study Arms (2)

extraction treatment

ACTIVE COMPARATOR

patients will be referred for extraction of the upper and lower first premolars to relieve the crowding.

Procedure: extraction orthodontic treatment plan

non-extraction treatment

NO INTERVENTION

Leveling and alignment of the moderate crowding will be performed through a recall visits of 4 weeks for wire activation. inter-proximal reduction step might be done if needed.

Interventions

extraction orthodontic treatment plan PROCEDURE

patients will be referred for extraction of the upper and lower first premolars then orthodontic treatment will follow.
