The CONO-IN® Zygomatic implant is Leader Medica’s high-precision extra-long fixture (30 to 60 mm) engineered with an authentic 1°+1° (2° total) Morse Taper cold-weld connection. Developed for extreme maxillary atrophy (Cawood & Howell Class V and VI) in Quad-Zygoma and Hybrid-Zygoma reconstructions, it anchors firmly into the dense zygomatic malar bone arch to deliver immediate functional loading without bone grafts.

1. Surgical Principles & ZAGA Anatomical Pathways

• Severe Maxillary Atrophy Rehabilitation: Provides solid skeletal anchorage for patients with complete loss of alveolar bone volume where conventional implants are impossible.
• Bypassing Major Iliac Crest Grafts: Completely avoids invasive autologous hip bone grafting, hospital stays, and lengthy 12–18 month consolidation periods.
• Immediate Full-Arch Loading: Rigid fixation in the malar bone delivers insertion torques of 50–70 Ncm, enabling immediate fixed cross-arch provisionalization within 24 hours.

2. 2° Morse Taper Connection Advantage in Zygomatic Spans

• Mechanical Cold-Welding: Completely neutralizes micro-rotational deflection across extended 30–60 mm cantilever lever arms.
• Hermetic Bacterial Barrier: Shrinks interface micro-gaps below 0.5 µm, preventing intraoral pathogens from tracking into the malar and orbital tissues.

3. DAS® Bioactive Surface & Grade 4 Titanium

• High-tensile Grade 4 pure titanium with optimized yield strength.
• DAS® dual-acid etched subtractive surface decontaminated with cold Argon-Oxygen glow-discharge plasma.
