An efficient three dimensional universal guide for accurate placement of mini implants

Abstract

Anchorage refers to the resistance against displacement by anatomical structures and the control of anchorage is one of the main factors for determining the success of orthodontic treatment. Conventional means of anchorage system were extra-oral and intra-oral anchorage. Evolution of intra-oral skeletal anchorage provided “Absolute Anchorage” using dental implants, miniplates and mini implant for fixed appliances which demanded stationary type of anchorage. Success of orthodontic mini implant depends on root proximity of the screw, cortical bone thickness and placement angle. In this article, we have described a grid for site selection and a well designed standard placement guide to prevent the root proximity while insertion, and reduce the chance of implant failure.
