Brief Summary

Thirty six patients needs therapeutic extraction of the maxillary first premolars with subsequent retraction of the maxillary canines will be divided randomly into two groups : piezocision group and the ER:yttrium aluminum garnet (YAG) laser group. In each group, piezocision or hard laser-assisted flapless corticotomy will randomly assigned to one side of the maxillary arch at the first premolar region, and the other side served as the control. Canine retraction will be initiated after completion of the leveling and alignment phase via closed nickel-titanium coil springs applying 150 g of force per side, soldered trans-palatal arch will be used as an anchor unit. Pre- and post distalization dental casts will be evaluated to study rate of canine distalization, canine rotation and anchorage loss over a follow-up period until a Class I canine relationship is achieved. The levels of pain and discomfort will be self-reported using a questionnaire with visual analog scales administered at four assessment times during the first month after the minimally invasive procedure.

Conditions

Outcome Measures

Primary Outcomes (1)

  • Rate of canine retraction

    The distance traveled by mm is divided by the time required in weeks.

    This will be measured immediately at the end of the tooth movement, i.e. when the retracted canine reaches its final position which takes up to 12 weeks

Secondary Outcomes (3)

  • Rate of molar anchorage loss

    This will be measured immediately at the end of the tooth movement, i.e. when the retracted canine reaches its final position which may take up to 12 weeks

  • Change in canine rotation

    This will be measured at the following assessment times: T1: baseline, T2: after 4 weeks of canine retraction, T3: after 8 weeks of canine retraction, T4: when the canine reaches its final position up to 12 weeks

  • Change in the levels of pain and discomfort

    These levels will be assessed at: one day following the intervention, one week, two weeks, and four weeks following the intervention.

Study Arms (2)

Piezosurgery

EXPERIMENTAL

In one half of the dental arch, piezosurgery will be performed for canine retraction, whereas in the other half ordinary canine retraction procedure will be followed.

Procedure: Piezosurgery

ER:YAG Laser

EXPERIMENTAL

In one half of the dental arch, ER:YAG laser irradiation will be performed for canine retraction, whereas in the other half ordinary canine retraction procedure will be followed.

Radiation: ER:YAG laser

Interventions

  • Class II Division 1 malocclusion :
  • Mild / moderate skeletal Class II (sagittal discrepancy angle ≤7)
  • Overjet ≤10

  • patients have anti indication for oral surgery ( medical - social - psycho)
  • Presence of primary teeth in the maxillary arch
  • Missing permanent maxillary teeth (except third molars).
  • Poor oral hygiene or Current periodontal disease:
  • Probing depth ≥ 4 mm
  • radiographic evidence of bone loss
  • Gingival index \> 1
  • Plaque index \> 1
  • Patient had previous orthodontic treatment
