Efficacy of Biological Technique in Upper Canine Retraction and Levels of Discomfort
Syria20 participantsStarted 2017-08-20
Plain-language summary
Twenty patients need therapeutic extraction of the maxillary first premolars with subsequent retraction of the maxillary canines, will be divided randomly into two groups, and will randomly assigned to one side of the maxillary arch at the first premolar region , and the other side served as the control. canine retraction will be initiated after completion of the leveling and alignment phase via closed nickel-titanium coil springs applying 150 g of force per side , soldered transpalatal arch will be used as an anchor unit.
Pre- and post distalization dental casts will be evaluated to study rate of canine distalization, over a follow-up period until a Class I canine relationship will be achieved. The levels of Pain and discomfort will be monitored using a questionnaire with a VAS scale administered three times during the first day after prf injection.

What they're measuring
1
Change of the rate of canine retraction
Timeframe: Before the beginning of canine retraction and every 28 days until the canines will be in the proper position (class 1) which will be approximately after 6 months from the beginning of canine retraction
