Detailed description

The aim of the present clinical study was directed to evaluate the effectiveness of micro-osteoperforations on the rate of canine retraction; in addition, the potential risk for root resorption during maxillary canine retraction. This study was conducted on a total sample of 24 canines of 12 patients, 8 females and 4 males, with mean age was 16.17 ± 2.29 years old who required therapeutic extraction of maxillary 1st premolars and canine retraction. They were selected randomly from the Outpatient Clinic, Department of Orthodontics, Faculty of Dental Medicine (Boys), Al-Azhar University, Cairo, Egypt. Both maxillary canines, in each patient, were randomly assigned to either an experimental side or the control side in a simple split-mouth design. In the experimental side, micro-osteoperforations was performed distal to the maxillary canine before starting retraction, while the canines in the contralateral control side were retracted without micro-osteoperforations. Extraction was done at the start of the treatment, and before fitting of the orthodontic appliance. Then upper dental arches were leveled and aligned using conventional sequences of wires. Three flapless micro-osteoperforations was performed by using orthodontic miniscrews distal to the maxillary canines in the experimental side before starting retraction. Each perforation was 1.6 mm in diameter and 3-4 mm depth into the bone. Canines were completely retracted on 0.016 × 0.022 ̋ stainless steel wires by using closed coil spring delivered 150 gm force. Patients were followed up every 28 days until complete canine retraction. Routine orthodontic records were obtained for each patient before treatment. Additionally, a full skull CBCT images were taken before treatment and immediately after canine retraction. The rate of canine retraction was assessed clinically; in addition, cone beam CT (CBCT) scans were used to assess the amount of canine retraction root length changes. Also anchorage loss of first permanent molars were assessed. The treatment results were compared clinically and radiographically (CBCT).
