Summary

This study aims to assess the dental changes, periodontal health and the pulp vitality in mini-screw supported en-masse retraction associated with traditional or flapless corticotomy techniques.

40 adult patients exhibiting class II division 1 malocclusion requiring upper first premolar extractions followed by en-masse retraction will participate in the study. They will be randomly and equally distributed into two groups: traditional corticotomy (20 patients) versus flapless corticotomy (20 patients). The corticotomy procedure will be performed pre-retraction. The dental changes will be assessed using dental casts. The impressions will be taken after finishing the leveling and alignment phase and before starting the en-masse retraction (T0), 1 month (T1), 2 months (T2), 3 months (T3), 4 months (T4), and 5 months (T5) following the onset of en-masse retraction. The final impression will be considered at the end of the en-masse retraction (when the canines reach Class Ι relationship).

Conditions

  • Class II Division 1 Malocclusion

Interventions

PROCEDURE

Traditional corticotomy

A full-thickness mucoperiosteal flap will be elevated including the interdental papilla, and extended from the distal side of the second premolar on the right side to the same position on the left side without performing any vertical releasing incisions. Then, one vertical incision between the roots of upper anterior teeth and two vertical incisions in the site of first premolar extraction will be made by the piezosurgery knife.

PROCEDURE

Flapless corticotomy

Vertical soft-tissue incisions will be made on the buccal and palatal gingiva by using a blade N.15. One incision will be made between the roots of the six upper anterior teeth, and two incisions will be made between the upper canines and the second premolars.
