  6. Soft tissue impaction Crown is erupted through bone Under the gingiva Tx Incise gingiva Section if necessary Luxate / subluxate Extract Impaction

  7. Partial bony impaction Crown is partially erupted through bone, under gums. Tx Incise gingiva Section tooth Extract pieces of tooth. Impaction

  8. Full bony impaction Crown of tooth (entire tooth) is covered w/ bone. Tx Incise gingiva Remove bone to expose tooth. Section tooth Remove pieces Impaction
