Aim: This case report demonstrates the successful retrieval of orthodontic mini-implant. Background: The idea of absolute anchorage has always been an evasive goal for clinicians. Tooth movements that are arduous to move can be achieved by orthodontic mini-implants or temporary anchorage devices. Since 1997, there is plenty of evidence available on mini-screw implant placement, which has been used for anchorage. But ample of evidence exists on how to use the anchoraging systems, and their failures have been merely focused upon, especially mini-implant fracture. Case description: Two case reports of mini-implant fracture on 45, 46 regions and one case report on 25, 26 regions are been discussed. A 1.6 × 8 mm stainless steel mini-implant (Ortho One) was used as a temporary anchorage device. The probable cause of mini-implant fracture was the improper angulation of mini-implant during placement and thick cortication of bone. After attaining adequate anesthesia, the surrounding bone was removed circumferentially using carbide bur under copious saline irrigation. With the help of Howe's plier, the mini-implant is retrieved. After achieving hemostasis, simple interrupted sutures are placed. Postoperative instructions, antibiotics, and analgesics are prescribed. Conclusion: Anchoraging devices fracture is an unusual clinical presentation and has to be treated wisely. A meticulous understanding of the biological and mechanical properties of anchoraging systems and clinical experience should be important in circumventing the clinical complications. Clinical significance: Mini-screws are valuable tools that increase and improve the quality of orthodontic treatment if properly used. There is hardly any evidence of fractured mini-implant case reports on it. The subsequent case report marked out the successful management of fractured mini-implant. It is a rare clinical chance that has to be managed judiciously. A methodical understanding of the biological and mechanical aspects of anchoraging systems would be helpful in bypassing complications.
