Brief Summary

Orthodontic therapy allows for the treatment of dental malpositions in order to produce an adequate relationship between teeth during occlusion. Conventional orthodontic therapy applies slight forces and moves teeth slowly. It is generally performed during a 2 year minimum of time. Recent studies seem to suggest that orthodontic therapy time can be shortened by surgical assistance (corticotomy). This investigation is aimed to determine the velocity of tooth movement and changes in periodontal clinical parameters between corticotomy-assisted orthodontic therapy and conventional orthodontic therapy.

Outcome Measures

Primary Outcomes (1)

• Changes in tooth position

  0 days, 7 days, 15 days, 1st month, 2nd month, 3rd month and 4th month after surgery and conventional orthodontic

Secondary Outcomes (1)

• Periodontal Clinical Parameters

  0 days, 7 days, 15 days, 1st month, 2nd month, 3rd month and 4th month after surgery and conventional orthodontic

Study Arms (2)

Corticotomy-assisted orthodontics

EXPERIMENTAL

This group of patients will receive corticotomy surgical procedure at day 0. Orthodontic activation will start immediately after surgery.

Procedure: Corticotomy

Conventional orthodontics

ACTIVE COMPARATOR

This group of patients will receive conventional orthodontics starting at day 0.

Procedure: Conventional orthodontics

Interventions

Corticotomy PROCEDURE

After a periodontal full flap is dissected, by using small round burs, vertical lines (2 mm depth corticotomy) parallel to each root of the teeth in the anterior segment (canines and incisors) are created 5 mm beyond the apex in the maxillary bones and interconnecting the lines at the apex by horizontal corticotomies. Marginal bone crest is not touched by the surgical procedure.

Also known as: Osteotomy

Conventional orthodontics PROCEDURE

Conventional orthodontic treatment
