title: [A clinical observation of combined application of magnetic attachments and extracoronal attachments].
abstract: OBJECTIVE
  To explore the clinical effect of combined application of magnetic attachments and extracoronal attachments in prosthodontics.
  
  
  METHODS
  Twenty-two cases of dentition defect with isolated residual root or residual crown were selected. All the cases accepted the restorative treatment combined magnetic attachments with extracoronal attachments. The clinical effect of dentures and the condition of abutment teeth were evaluated by chief complaint of patients and clinical examination. The follow-up time ranged from 2 years to 4 years.
  
  
  RESULTS
  Satisfactory functional, stable and esthetic results of dentures were achieved for all the cases. And there was no abutment loosening and no secondary caries. Alveolar bone loss around abutment occurred in 1 case, gingivitis of abutments appeared in 5 cases. Chewing pain occurred in 1 case and unstable state of dentures appeared in 5 cases after the use of denture for 2 years. The dentures of above-mentioned cases were used normally after symptomatic treatment.
  
  
  CONCLUSIONS
  The combined application of magnetic attachments and extracoronal attachments in prosthodontics is an effective treatment option for cases of dentition defect with isolated residual root or residual crown.
