title: [Combined orthodontic-periodontal treatment on periodontal patients with anterior displaced incisors].
abstract: OBJECTIVE
  Combined orthodontic-periodontal treatment with supracrestal fiberotomy was undergone on the periodontal patients with anterior displacement of incisors. Evaluate of the changes before and after treatment.
  
  
  METHODS
  Periodontal indices, periapical x-ray analysis, and model analysis were used for investigating the changes of alveolar bone height and periodontal health by orthodontic treatment following supracrestal fiberotomy of anterior displaced incisors on periodontal patients.
  
  
  RESULTS
  Alveolar bone height was increase by 1.2 mm in fiberotomy patients. The overjet was reduced from 7.0 mm to 2.0 mm, while the overbite was decreased from 4.0 mm to 2.0 mm, and the periodontal health maintained as well.
  
  
  CONCLUSIONS
  Combined orthodontic periodontal treatment with supracrestal fiberotomy could correct the malpositioned teeth, and improve the periodontium conditions and gain the crest bone.
