Outcome Measures

Primary Outcomes (1)

  • Efficiency of aligners in molar distalization

    T2(3shape)-T1(actual) \<mm\>

    6 months

Secondary Outcomes (2)

  • Amount of anchorage loss

    6 months

Study Arms (2)

Molar distalization by aligners without attachment

ACTIVE COMPARATOR
Device: Molar distalization by aligners with attachment

Molar distalization by aligners with attachments

EXPERIMENTAL
Device: Molar distalization by aligners with attachment

Interventions

1. Plaster dental models will be poured from the rubber base impression. 2. Digital dental models will be created through scanning of plaster dental models. 3. Planning of the aligners will be done on 3 shape clear aligner. 4. Aligners will be fabricated on 3d printed models. 5. Patient will receive the first aligner and will be instructed to wear it full time (except during eating and brushing) for 2 weeks. 6. Patient will receive the following aligner after 2 weeks. 7. Follow up visits every 4weeks until 6 months.

You may qualify if:

  • Age more than15 years.
  • Gender; male or female.
  • Skeletal Class I or Class II malocclusion and a bilateral half-cusp class II molar relationship that require molar distalization.
  • Mild crowding in the upper arch (≤ 4 mm).
  • Absence or previous extraction of the upper third molars.
  • Good compliance during the treatment

You may not qualify if:

  • Transversal dental or skeletal discrepancies.
  • Extraction treatment (except for the third molar).
  • Periodontal disease. .
  • Prosthodontics rehabilitation of the maxillary molars.
