title: A new attachment for proximal segment positioning for bimaxillary dysgnathic surgery--technical note.
abstract: BACKGROUND
  The frequent insertion of self-tapping screws for securing the proximal positioning plate in bimaxillary osteotomy often cause loosening of screws and plate, which produces incorrect repositioning. In this article, a newly developed base-attachment for a T-shaped proximal positioning plate for bimaxillary osteotomy is presented.
  
  
  METHODS
  The base-attachment set consists of a titanium base-attachment and two titanium tapped screws. The attachment has a shallow depression having the same shape as the basal part of the positioning plate.
  
  
  METHODS
  The base-attachment is secured by self-tapping screws until the end of the procedure, and the T-shaped proximal positioning plate is placed and secured by two titanium-tapped screws.
  
  
  RESULTS
  By using this base-attachment, the T-shaped plate can be easily placed repeatedly without difficulty.
  
  
  CONCLUSIONS
  This base-attachment set may be useful for the frequently repositioned proximal plate in bimaxillary osteotomy.
