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.
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.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| full thickness mucoperiosteal flap | Experimental | 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. |
|
| low level laser therapy | Experimental | 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 |
|
| Control for Full thickness mucoperiosteal flap | No Intervention | Control for Full thickness mucoperiosteal flap, in which canine retraction was done in a conventional method | |
| control for Low level laser therapy group | No Intervention | Control for Low level laser therapy , in which canine retraction was done in a conventional method |
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| elevation of full thickness mucoperiosteal flap | Procedure | A free gingival sulcular incision was done from the distal surface of maxillary second premolar to the mesial side of the maxillary canine. A releasing oblique incision was done including the interdental papilla between maxillary canine and lateral incisor extending to the mucogingival junction just beyond the attached mucosa. The flap reflection extended beyond the canine root apex. A FTMPF reflection was done with mucoperiosteal elevator. Free sulcus incision was done to allow elevation of palatal mucosa by tunneling technique on the palatal gingiva of maxillary canine. |
| Measure | Description | Time Frame |
|---|---|---|
| rate of orthodontic tooth movement acceleration determination by measuring the rate of maxillary canine retraction | measure the rate of canine retraction on series of study models | 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 | Description | Time Frame |
|---|---|---|
| clinical mesial movement of first maxillary molar measured by millimeter on the 3D model | amount of mesial movement of first maxillary molar after 24 month | t0(start of canine retraction) to 24 months |
