Mini-implant Placement Guiding Device (MIG-20): An Innovative 3D Guide

Mini-implant or temporary anchorage device (TAD) have now become an important aspect in the Orthodontic practice worldwide. It has increased the envelope of discrepancy for Orthodontic correction, as more anchorage can be harnessed owing to TAD’s. Placement of mini-screw in particular has to be very precise in order to get maximum anchorage without hampering adjacent structures like tooth root and periodontal ligament. Angulation of the screw with respect to bone is of equal importance to gain biomechanical advantage and achieve necessary stability. We have developed a 3-D mini-implant guide, called MIG-20 using basic orthodontic material and then its final design was casted. Placement and working of MIG-20 is explained in this article. Design of MIG-20 has been patented by the authors and the working is been copyrighted. A study has been conducted to evaluate the accuracy of MIG-20 on patients. It has proven to give accurate results in mini-screw placement.
