简要总结
This study aimed to evaluate the effect of using full thickness mucoperiosteal flap (FTMPF) elevation only versus low level laser therapy (LLLT) on acceleration of orthodontic tooth movement.
详细描述
This study was a split mouth design study included 32 side according to sample size calculation. Those sides were divided into 2 groups. Group 1divided into (group 1a: 8 sides with FTMPF, group 1b:8 sides control). Group 2(group 2 a: 8 sides with LLLT, group 2b: 8 sides control). Extraction of the first maxillary premolars followed by canine retraction in the extraction space with maximum anchorage were indicated. FTMPF was elevated from the mesial interdental papilla of maxillary canine to the mesial interdental papilla of second maxillary premolar. LLLT was applied at 3,7,14,28.56 days of retraction. During retraction study model for all patients were taken at 2ed, 6th, 14th,16th weeks and at the end of retraction (I1,I2,I3,I4,I5 or overall interval). 3D laser scanning and digital superimposition was done to measure the rate of canine retraction and anchorage loss.

入选标准
- •o Free of any syndromes affecting the head region or any craniofacial injuries.
- •No history of previous orthodontic treatment
- •All of the permanent dentition present excluding third molars.
- •Good oral hygiene before starting treatment.
- •Cases indicated for extraction of the maxillary first premolars and canine retraction into the extraction space with maximum anchorage.

研究组 & 干预措施
full thickness mucoperiosteal flap
A full thickness mucoperiosteal flap (FTMPF) was reflected on FTMPF side at the maxillary canine/premolar region by the same surgeon for all patients following the same procedures.
干预措施: elevation of full thickness mucoperiosteal flap (Procedure)
low level laser therapy
LLLT was done using a diode soft laser (Epic X, BioLase, USA). It is a semiconductor diode soft laser. Active medium is In-Ga-As with 940nm wave length
干预措施: low level laser therapy (Device)
Control for Full thickness mucoperiosteal flap
Control for Full thickness mucoperiosteal flap, in which canine retraction was done in a conventional method
control for Low level laser therapy group
Control for Low level laser therapy , in which canine retraction was done in a conventional method
结局指标
主要结局
rate of orthodontic tooth movement acceleration determination by measuring the rate of maxillary canine retraction
时间窗: the rate of retraction( distance from the first day of retraction to the end of retraction/ time)) it was with total time frame 24 weeks for starting of retraction
measure the rate of canine retraction on series of study models
次要结局
- clinical mesial movement of first maxillary molar measured by millimeter on the 3D model(t0(start of canine retraction) to 24 months)
