K.F Mini- Implant Placement Guide: A Simplified Template for Mini-Implant Placement in Orthodontics.

Abstract Background Orthodontic mini‑implants (MI) have gained popularity among orthodontists mainly because they provide an effective tool in orthodontic cases with high anchorage demands. The main objective of this study is to avoid a risk of injury to dental roots during placement of orthodontic mini-implants, especially when they are inserted between teeth and design a placement guide which is simple in design, easy to fabricate, inexpensive, supportive and can be used with a variety of mini-screws. Findings The mini-implant placement guide was fabricated using rectangular 0.017 x 0.025/0.019 × 0.025 stainless steel (SS) archwire, the wire was bent vertically distal to second premolar along the long axis. The vertical length of the wire is according to the desired length for micro-implant insertion, which is generally 5-6 mm apical to the alveolar crest. After the vertical bend 2-3 mm (which is an interradicular space between two roots) [8] horizontal bend is given pointing posteriorly towards the first molar region. A periapical radiograph is taken to confirm the correct position of template guide, radiograph is repeated until the desired position is achieved. The point of mini-implant insertion site is just at the middle of the horizontal bend, which can be readily marked using a marker or a burr. Conclusion K.A. micro-implant placement guide is simple in design, easy to fabricate, inexpensive, supportive and can be used with a variety of mini-screws.
