NCT02416297

Brief Summary

The purpose of this research study is to assess the clinical effectiveness of a minimally invasive alveolar microperforation procedure to achieve accelerated tooth movement in patients undergoing orthodontic treatment for orthognathic surgery. "Accelerated tooth movement" means that Microperforation technique may help complete orthodontic treatment sooner than would be expected in conventional orthodontic treatment

Outcome Measures

Primary Outcomes (1)

  • Evaluation of velocity rate of anterior retraction in conventional mechanics and accelerated tooth movement technique

    The micro osteoperforations accelerates tooth moviment - Null hipothesis

    6 months

Study Arms (2)

Micro-osteoperforation

EXPERIMENTAL

Minimally invasive micro-osteoperforation procedure used to achieve accelerated orthodontic tooth movement. Topical and local anesthetic will be delivered in the area to be treated in accordance with standard practice.

Procedure: Micro-osteoperforation

Control

NO INTERVENTION

Anterior retraction after premolars extraction will be done conventionally (slide mechanics)

Interventions

Flapless cortical perforations will be made 8 months minimum after dental extraction. Surgical protocol will be flapless to preserve periodontal health. After local anesthesia, 3 micro osteoperforations will be done with manual instrument, between apex to the contour of free gum between the canine and second pre-molar. Perforations near each tooth will have 6-8 mm depth

Micro-osteoperforation
