简要总结
The aim of this clinical prospective study will be directed to evaluate two approaches of micro-osteoperforations (MOPs) during orthodontic canine retraction.
详细描述
The aim of the present clinical study was directed to evaluate the effectiveness of two approaches of micro-osteoperforations (MOPs) during orthodontic canine retraction.
This study was conducted on a total sample of 36 canines of 18 patients, 15-22 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.
they were randamly dived into two groups:as follows: Group I: include 9 patients , MOPs were performed for one time only on one side before retraction.
Group II: include 9 patients , MOPs were performed on repeated basis on one side.
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 at equal distance between maxillary canine and 2nd premolar before starting retraction, while the canines in the contralateral control side were retracted without micro-osteoperforations.

- •Age range from 15-22 years.
- •Malocclusion cases that require maxillary first premolars extractions followed by symmetrical canine retraction.
- •All permanent teeth present, 3rd molars are excluded.
- •Good oral and general health.
- •No systemic disease/medication that could interfere with OTM.
- •No previous orthodontic treatment.
排除标准
- •Patient diagnosed to have an indication for non-extraction approach.
- •Poor oral hygiene or periodontally compromised patient.
- •Patient with craniofacial anomalies or previous history of trauma, bruxism or parafunctions.

研究组 & 干预措施
control side
Conventional side Canine retraction was commenced without micro-osteoperforations.
single Micro-osteoperforations side
Three flapless micro-osteoperforations (MOPs) was performed for one time only distal to the maxillary canine before starting retraction.
干预措施: micro-osteoperforations (Procedure)
Multiple Micro-osteoperforations side
Three flapless micro-osteoperforations (MOPs) was performed on repeated basis distal to the maxillary canine evey 28 days before canine retraction.
干预措施: micro-osteoperforations (Procedure)
结局指标
主要结局
Rate of canine retraction
时间窗: change from start of canine retraction until 4 months .
clinically, patients were evaluated immediately before canine retraction and every 28days until for months. 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.
