title: Microscrew implant anchorage sliding mechanics.
abstract: OBJECTIVE
  To show the effectiveness of sliding mechanics used with microscrew implants in managing a dentoalveolar protrusion. There are several advantages, including reduced treatment time, simplified treatment mechanics, early profile changes, and elimination of interarch mechanics.
  
  
  METHODS
  A step-by-step procedure for microscrew implant anchorage sliding mechanics is shown, with records of treated patients, which demonstrate the aforementioned advantages of this technique. The associated biomechanics and theoretical explanation follow.
  
  
  RESULTS
  The authors show how the microscrew implant can provide anchorage for en masse retraction of six anterior teeth and the efficiency and ease of the mechanics in managing a dentoalveolar protrusion.
  
  
  CONCLUSIONS
  The microscrew implant offers orthodontic clinicians a minimally intrusive method of intra-arch anchorage that can retract the anterior teeth without the anchorage loss that is expected in conventional techniques. Sliding mechanics used with microscrew implants is shown to be simple and efficient.
