Interventions

Intervention1: EN-MASSE RETRACTION USING SLIDING MECHANICS ALONG WITH INTRUSION SPRINGS: Changes in position and inclination of maxillary molar and incisor will be measured in terms of anchorage loss,

Eligibility

Inclusion criteria

Inclusion criteria: 1) Patients older than 15 years to minimize the effect of growth. 2) Patients with proclined maxillary incisors. 3) Patients requiring camouflage treatment by extraction of upper first premolars. 4) Patients requiring maximum anchorage during space closure. 5) Patients with no or minimal crowding in the maxillary arch less than 3mm. 6) Fully erupted permanent dentition except for the third molar. 7) Good oral hygiene

Exclusion criteria

Exclusion criteria: 1) Patients with severe crowding in maxillary arch. 2) Patients requiring absolute anchorage where mini-implants may be desired. 3) Missing permanent teeth other than third molars. 4) Patients with any systemic disease or syndromes or any other craniofacial abnormalities. 5) Patient under medications that may affect orthodontic tooth movement.
