Mesial Movement of Teeth
Conditions
Brief summary
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.
Detailed description
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
PROCEDUREelevation of full thickness mucoperiosteal flap
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.
DEVICElow 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. LLLT protocol was using active laser tip (bleaching tip)
