title: [Clinical evaluation of glass fiber-reinforced composites for fixed orthodontic lingual retainers].
abstract: OBJECTIVE
  The purpose of this clinical evaluation was to assess the clinical effect of application of everStick Ortho glass fiber-reinforced composites for orthodontic lingual retainer.
  
  
  METHODS
  A total of 12 patients underwent orthodontic treatment using glass fiber-reinforced composites for fixed orthodontic lingual retainers. During a 24-month follow-up period after application of retainers, the condition of lingual retainers and the periodontal status were examined every 6 months. Gingival index and sulcus bleeding index were analyzed by nonparametric tests with SPSS 13.0 software package.
  
  
  RESULTS
  During 24-month follow-up period, 11 orthodontic lingual retainers were stable without fracture while the periodontal tissue revealed no significant changes in all 12 patients.
  
  
  CONCLUSIONS
  The application of everStick Ortho glass fiber-reinforced composites for orthodontic lingual retainer is a viable alternative to conventional retainer used in orthodontic treatment.
