Abstract

Introduction: Mini implants have been researched extensively in terms of their efficiency, material used, and methods of accurate placement. When properly used,they might be a substitute method of anchorage preparation as compared toconventional molar anchorage and might reach alike or even superior results in certaincases.
Aim: The present study aimed to evaluate and compare accuracy and stability of orthodontic temporary anchorage device with and without the use of Mini-implantplacement guiding device (MIG-20) in adults.
Each patient underwent implant placement using both methods to have a similar oral environment for groups. Each case was treated in a split-mouth pattern to eliminateselection bias (to have the same baseline characteristics for both groups). Sideselection for that particular method was undertaken by using computer-generatedrandomization. So in all 2 groups were categorized. Mini-implant inserted by theconventional method (Control Group). Group II: Mini- Implant inserted by using MIG-20. Mini-implants were placed on both sides of the maxillary jaw between the 1 st molarand 2 nd premolar with the self-drilling manual method. Evaluation of clinical pictures, pre and post RVG and stability/mobility were done for each sample in both groupsusing AutoCAD software 2013.
Results and Observations: Out of 21 cases in Control group, it was observed that100% of cases in Control group had a vertically deviated mini-implant, which was statistically significant as compared to Study group, where 28.57% (6) cases demonstrated vertical deviation and 71.43 % (15) cases, where no deviation of miniimplantwas seen in vertical dimension when observed clinically. (p=0.0001, S). In71.43 % of cases, no significant variation was observed clinically in Study Group inmesiodistal dimension. (p=0.0001, S).
Conclusion: The findings of the study substantiate the effectiveness of the 3-D Mini-Implant placement guide (MIG-20) when compared to the conventional method, inachieving a more accurate mesiodistal and vertical placement of mini implants.
