Eligibility |
Inclusion Criteria: 1. An age ranged between 14 to 18 years. 2. Class II division 1 malocclusion or Class I bimaxillary protrusion with mild or no crowding. Wherever crowding was present, it was symmetrical on both sides of the arch. 3. Patients who diagnosed to require extraction of at least maxillary first premolars bilaterally as a part of their treatment plan. 4. Complete permanent dentition (3rdmolars were not included). 5. Good oral and general health. 6. No history of periodontal problems. 7. No therapeutic intervention planned involving intermaxillary or other intraoral or extraoral appliances during the study period. Exclusion Criteria: 1. Blocked out or impacted maxillary canines. 2. Transverse and/or vertical skeletal dysplasia or craniofacial anomalies. 3. Systemic diseases or regular use of medications that could interfere with orthodontic treatment. 4. Previous orthodontic treatment. |

Primary | Rate of canine retraction | Clinically, patients were evaluated immediately before canine retraction and every 4 weeks till complete space closure (complete canine retraction). It was based on measuring the distance between the contact points on the distal surface of the canines and the contact points on mesial surface of the second premolars. |
change from start of canine retraction until complete space closure up to 6 months | |
Primary | Canine root length changes | The CBCT scans were taken before orthodontic treatment and after complete space closure (canine retraction) to be analyzed for assessment of Canine root length changes. The root length was measured along the axis of the root, perpendicular to a line connecting the buccal and palatal cemento-enamel junction CEJ in sagittal view |
change from start of orthodontic treatment until complete space closure up to 9 months | |
Secondary | Anchorage loss of maxillary first permanent molars. | mesial movement of maxillary first permanent molars bilaterally was measured before orthodontic treatment and after complete space closure ( canine retraction) on CBCT scan which were taken before orthodontic treatment and after complete canine retraction The distance measured along perpendicular from distal surface of 1st permanent molar to Ptv plane | change from start of orthodontic treatment until complete space closure up to 9 months |
