简要总结
In this prospective clinical trial, the changes on maxillary anterior teeth during en-masse retraction will be compared in the patients with and without anterior bite turbo. The outcome will be compared on the basis of movement of teeth in anteroposterior and vertical dimension.
Research Question:
What are the effects on linear and angular changes of maxillary anterior teeth in patients undergoing en-masse retraction with or without anterior bite turbo?
Methods:
Class II division 1 malocclusion patients will be recruited from post-graduate orthodontic clinic of Department of Dentistry.
Patients will be allocated into two groups:
Group I –Retraction with anterior bite turbo (Intervention group)
Group II – Retraction without anterior bite turbo (Control group)
PRIMARY OUTCOME
· To compare the angular and linear changes in maxillary anterior teeth in patients undergoing en-masse retraction with or without anterior bite turbo.
SECONDARY OUTCOME
· To compare the angular and linear changes in mandibular incisors, maxillary first molar, sagittal and vertical skeletal parameters in patients undergoing en-masse retraction with or without anterior bite turbo.
Data so obtained will be subjected to statistical evaluation.
