Effects of Flapless Laser Corticotomy in Canine Retraction

The flapless laser corticotomy will be done by Er, Cr: YSGG laser as a series of circular holes will be made along with the planned position. The depth of laser cutting will be measured and controlled continuously during the operation by the periodontal probe with stopper read to each 3mm depth in addition to a few parts of a millimetre depth into the medullary bone to enhance bleeding. Canine retraction will be started after this procedure.

canine retraction will be done on 17x25 stst archwire using coil spring adjusted to 150 gm, and miniscrews will be used as an indirect method of anchorage reinforcement
