Laser Verses Conventional Circumferential Supracrestal Fiberotomy in Orthodontic Extrusion for Crown Lengthening

"The amount of tooth that need to be extruded will be measured Bonding brackets slot 0,022x0.028 Roth prescription on piggyback for the tooth with (0.016. x 0.022 ) stainless steel main arch wire and 0.0014 nickel titanium auxiliary.~• Fiberotomy After 2 days of bonding, local anaesthetic solution will be administrated. The depth of the fibrotomy should be equal to the amount of tooth that need to be extruded.~supracrustal fibrotomy will be performed using 15 c blade (Carvalho, Bauer et al. 2006)"
