title: The use of miniplate osteosynthesis for skeletal anchorage.
abstract: BACKGROUND
  The purpose of this study was to explore the use of miniplates as skeletal anchorages for orthodontic treatment and to investigate the stability of miniplates and the causes of failure.
  
  
  METHODS
  Forty-four miniplates were applied in the maxilla or mandible as skeletal anchorages in orthodontic treatment. Two weeks later, a force of 100 to 200 g was applied by an elastometric chain or nickel-titanium coil spring to move the teeth. To compare nominal variables related to miniplate failure, the chi-square or Fisher's exact test was used.
  
  
  RESULTS
  The average insertion time of a miniplate was approximately 25 to 30 minutes. One miniplate loosened before orthodontic force loading. The other miniplate was removed after orthodontic force loading. The overall success rate was 95.5 percent. The authors found no significant differences in the risk factors for failure of miniplates.
  
  
  CONCLUSIONS
  Miniplates are easy to insert for skeletal anchorage, simplify treatment mechanics, and shorten the orthodontic treatment period.
