Summary

Patients with class II division 1 malocclusion who have increased overjet will be treated in this study. The efficacy of one-jaw and tow-jaw mechanics for mini-implants anchored total-maxillary-arch-distalization in the treatment of class II division 1 malocclusion will be assessed. The skeletal, dental and soft tissues changes resulted by these tow interventions will be studied. As well as, the pain levels, oral-health related quality of life during all stages of the treatment and the smile components will be explored and compared with the traditional treatment results of this type of malocclusion (en-mass retraction with first premolars extraction).

There are three groups :

1. a group of patients in which participants will be undergo to the one-jaw mechanic for mini-implants anchored total-maxillary-arch-distalization (mini-implants in the maxillary arch).
2. a group of patients in which participants will be undergo to the tow-jaw mechanic for mini-implants anchored total-maxillary-arch-distalization (mini-implants in the mandibular arch with class II elastics).
3. a group of patients in which participants will be undergo to the en-mass retraction with first premolars extraction with mini-implants in the maxillary arch.

Conditions

  • Malocclusion
  • Class II Division 1 Malocclusion

Interventions

OTHER

One-jaw mechanic total maxillary arch distalization

A group of patients in which participants will be undergo to the one-jaw mechanic for mini-implants anchored total-maxillary-arch-distalization (the mini-implants will be inserted in the maxillary arch between the roots of 2nd premolar and 1st molar and closer to the molar, then a force of 250 g will be applied from the TAD to a hook lateral to the laterals).

OTHER

Two-jaw mechanic total maxillary arch distalization

A group of patients in which participants will be undergo to the tow-jaw mechanic for mini-implants anchored total-maxillary-arch-distalization (the mini-implants will be inserted in the mandibular arch between the 2nd premolar and 1st molar, then, a class II elastics 3/16 and 6.5oz will be use from the TAD to the hook of canines brackets).

OTHER

en-mass retraction

A group of patients in which participants will be undergo to the en-mass retraction with first premolars extraction with mini-implants in the maxillary arch inserted between the 2nd premolar and 1st molar, then a force of 250 g will be applied from the TAD to a hook lateral to the laterals .
