Conventional methods and mini implants supported simultaneous retraction and intrusion of anterior segment help the clinician to achieve both retraction and intrusion at a same time and thus reducing the treatment time of the patient., To achieve simultaneous retraction and intrusion by any of the method it is important to consider the force system delivered on the anterior segment which depends on the point of application of the force and its direction. Majority of the studies stated that to achieve the bodily displacement of the anterior teeth, the force should pass through the centre of resistance. The key influencing factor in determining the degree and course of movement of anterior teeth during sliding mechanical retraction might be the length of the power arm and the position of the micro implants. This leads to a crucial clinical clue. So before starting the treatment, its mandatory to assess the problems, establish clear objectives of treatment, and develop adequate technique to achieve the established results. Thus, clinicians are encouraged to evaluate each patient to develop the proper biomechanics for each particular case that leads to effective treatment results.
