Abstract
Selected cases have been presented using different techniques to alter crestal levels. Self Regeneration or Autogenous bone grafts have been most successful in cases of three-wall and two-wall infrabony lesions. When a hemiseptal lesion occurs on the mesial of a tooth an uprighting procedure can be accomplished. When there is an adjacent tooth a forced eruption technique using orthodontic forces can be used. A surgical elevation technique has been presented which also has shown positive changes in bony topography.
