Horizontal bone loss, vertical/angular bone loss, osseous craters, bulbous bony contours, reversed bone architecture, ledges.
Bone loss is considered vertical when attachment & bone loss on one tooth surface is greater than that on adjacent surface & is associated with intrabony pocket formation. In horizontal bone loss, bone loss occurs at uniform rate & is associated with suprabony pocket. Vertical defects are classified as: one wall (one wall remaining), two wall (two wall remaining) & three wall defects (three wall remaining). A vertical defect that involves more than one tooth surface is called as circumferential defect.
