The Universal Extraction Kit from Leader Medica Italy is a revolutionary, minimally invasive explantation system designed to remove fractured, stripped, mechanically compromised, or failed implants without destructive trephine burs. By preserving 100% of the surrounding alveolar bone housing, it enables immediate re-implantation within the exact same surgical appointment.

1. Bone-Preserving Atraumatic Explantation Mechanism

• Trephine Bur Elimination: Traditional trephines sacrifice 2–3 mm of circumferential bone volume, creating extensive bone defects. The Leader Medica kit operates strictly from within the implant core, keeping the surrounding cortical and cancellous bone plates intact.
• Hardened Reverse-Threaded Micro-Expanders: Precision reverse-threaded mandrels machined from medical-grade surgical alloy that thread counter-clockwise into the internal chamber of the fixture, locking solidly to back the implant out of the osteotomy.
• TIDINA Precision Progressive Torque Ratchet: Calibrated ratchet wrench delivering smooth, controlled progressive removal torque up to 35 Ncm, safely breaking osseointegration micro-contacts without shock or fracture to the jawbone.

2. Universal Multi-Brand Compatibility

• Comprehensive Interface Adapters: Includes mandrels and extractors compatible with internal hexagon, external hexagon, internal conical, and Morse taper connections across leading global implant manufacturers.
• Autoclavable Surgical Cassette: High-grade medical polymer tray resistant to 134°C steam sterilization with an intuitive, organized layout.

3. Primary Clinical Indications

• Explantation of fractured fixtures caused by metal fatigue, parafunction, or occlusal overload.
• Removal of malpositioned, non-restorable implants without causing cortical plate loss.
• Management of severe refractory peri-implantitis requiring fixture replacement.
• Immediate re-implantation protocols where bone preservation is critical.
