Full Thickness Mucoperiosteal Flap Versus Low Level Laser in Orthodontic Tooth Movement Acceleration

Al-Azhar University32 enrolled

Overview

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.

Interventions

elevation of full thickness mucoperiosteal flapPROCEDURE

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.

low level laser therapyDEVICE

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. LLLT protocol was using active laser tip (bleaching tip)

Outcomes

Primary Outcomes

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

Time frame: 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

Secondary Outcomes

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

Time frame: t0(start of canine retraction) to 24 months
