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

Evaluation of the Effect of Full Thickness Mucoperiosteal Flap Versus Low Level Laser in Orthodontic Tooth Movement Acceleration

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.

Inclusion Criteria:

• 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.
  • Malocclusion cases that allow initial stage of leveling and alignment without extraction.

Exclusion Criteria:

• o Patients with systemic diseases especially bleeding disorders and osteoporosis.

  • History of administration of corticosteroids, exogenous hormones and non-steroidal anti-inflammatory drugs (all drugs interfere with OTM).
  • Presence of previous history of oral surgeries in maxillary arch.
