The MITO Nasal implant is Leader Medica’s extended-length solution (16 to 22 mm) built upon the proven 2.42 mm internal hexagon platform. Engineered for bicortical engagement into the dense cortical floor of the nasal cavity in patients presenting with severe anterior maxillary atrophy, it combines universal prosthetic interchangeability with immediate loading stability without bone grafts.

1. Clinical Merits of Nasal Cortical Anchorage

• Bicortical Purchase in Resorbed Ridges: Engages the crestal cortical plate and the thick cortical floor of the nasal aperture, securing primary stability above 45 Ncm.
• Elimination of Bone Grafts: Completely avoids complex onlay bone block procedures, donor-site morbidity, and prolonged healing phases.
• Splinting & Immediate Function: Rigid bicortical stabilization allows immediate provisional cross-arch fixed bridge restorations.

2. Internal Hex Connection with 90° Shoulder

• 2.42 mm Internal Hexagon: Deep, positive rotational engagement resisting lateral masticatory forces.
• 90° Flat Shoulder: Tactile abutment seating and radiographic margin clarity.
• Double-Lead Progressive Coils: Dual-start threads deliver bone condensation along the cancellous body and rigid self-tapping grip at the nasal cortex.

3. DAS® Bioactive Surface & Grade 4 Titanium

• Grade 4 Titanium: High yield strength designed to endure bending moments across long spans.
• DAS® Dual-Acid Etch: Pure subtractive treatment (Ra = 1.35 µm) free from embedded alumina particles.
• Argon-Oxygen Cold Plasma Glow-Discharge: Imparts superhydrophilicity and total organic decontamination.

4. Surgical Protocol

• CBCT analysis to evaluate nasal floor thickness and incisive canal proximity.
• Long drills under copious external saline irrigation at 600–800 rpm.
• Engage 1 mm into the nasal cortical floor under tactile feedback.
• Final insertion torque: 40 to 50 Ncm.
