NCT05166928 | Unknown

• 1 other identifier: 627/1151
• Study Type: interventional
• Target: 16
• Locations: 1 country
• Sites: 1

Brief Summary

This clinical study will be directed to compare the effect of presence or absence of third molar on distalization of the upper posterior segment by using carriere motion appliance

Conditions

Class II Malocclusion

Outcome Measures

Primary Outcomes (1)

• change in upper first molar position

  using 3d cast superimposition

  Baseline to 6 months

Study Arms (2)

group 1: control group

ACTIVE COMPARATOR

will be treated using carriere motion appliance for distalization of upper buccal segment in the presence of upper third molar

Device: carriere motion appliance

group2: teste group

ACTIVE COMPARATOR

will be treated with using carriere motion appliance for distalization of upper buccal segment with upper third molar extraction or have congenital missing upper third molar

Device: carriere motion appliance

Interventions

carriere motion appliance DEVICE

after finished treatment with carrirere motion appliance in the two group (group 1 have upper wisdom teeth ,group 2 have not upper wisdom teeth ) the pre and post casts will be scanned and superimposed to determine amount upper molar distalization

group 1: control group; group2: teste group
