title: [A case of occlusal reconstruction for a patient with severe chronic periodontitis].
abstract: METHODS
  65 years old, female. Chief complaint:Esthetic problem of upper right incisor because of labial displacement. After initial periodontal therapy, a hawley bite plane was inserted to reposition the mandible and retract the anterior teeth. The anterior teeth were stabilized with pin ledge materials.
  
  
  CONCLUSIONS
  For a patient with severe chronic periodontitis, it is difficult to decide whether to replace or retain the remaining teeth. The hawley bite plane is effective in these cases in order to control occlusal trauma, to reposition the mandible, and to reduce teeth movements.
  
  
  CONCLUSIONS
  It is critical to evaluate the prognosis of each tooth through initial periodontal diagnostics in cases of severe chronic periodontitis. A treatment plan can then be created which will address all known etiologic factors.
