The Internal Hexagon MITO is Leader Medica’s robust, universal dental implant system engineered in Italy around a proven 2.42 mm wide and 2.2 mm deep internal hexagon. Featuring a 90° flat coronal shoulder, a conical core, and double-lead self-compacting coils, MITO delivers intuitive prosthetic verification, superior rotational locking, and outstanding primary stability across all bone types.

1. Connection Engineering & 90° Flat Shoulder

• 90° Flat Shoulder: The horizontal coronal shoulder guarantees positive, tactile abutment seating and crystal-clear marginal verification on periapical radiographs.
• Deep Internal Hexagon: Precision-machined 2.42 mm width and 2.2 mm depth provide uncompromising static resistance against cyclic lateral shearing forces, preventing micro-rotational play.
• M1.8 Retaining Screw: High-tensile medical Grade 5 titanium screw engineered for tightening torques up to 30 Ncm without thread deformation or fatigue stretching.

2. Double-Lead Self-Compacting Thread Architecture

• Double-Start Progressive Threads: Doubles insertion speed per revolution, minimizing surgical operative time and preventing frictional bone overheating.
• Apical-to-Coronal Transition: Deep, sharp cutting threads at the apical tip facilitate effortless self-tapping; gradually transitioning into wider, square-profile condensing threads coronally to compact cancellous bone while preserving dense crestal cortical bone.
• Cylindrical External Envelope with Conical Core: Combines external cylindrical guidance with internal conical bone condensation, securing high primary stability even in soft, trabecular bone (D3/D4).
• Dual Helical Apical Flutes: Two spiral cutting grooves evacuate bone chips efficiently, ensuring controlled insertion torques in dense D1 and D2 bone.

3. Grade 4 Titanium & DAS® Surface Treatment

• Medical Grade 4 Pure Titanium: Exceptional yield and tensile mechanical strength meeting European CE Class IIb medical standards.
• Pure Subtractive Dual Acid Etching (DAS®): Hydrofluoric acid activation followed by hydrochloric/sulfuric acid bath ( = 1.35,mu ext{m}$), free from abrasive alumina corundum grit blasting contaminants.
• Argon-Oxygen Cold Plasma Glow-Discharge: Purified under Prof. Luigi Canullo's protocol to eliminate 100% of organic hydrocarbons and create superhydrophilic bio-wettability.

4. Step-by-Step Surgical & Drilling Protocol

• Initial Osteotomy: Marking with a round bur, followed by a Ø 2.0 mm pilot drill at 800–1000 rpm under sterile saline irrigation.
• Sequential Expansion: Sequential drills (Ø 2.8, 3.2, etc.) at 600–800 rpm according to fixture diameter.
• Dense Bone Protocol: In dense cortical bone (D1/D2), a cortical countersink or bone tap should be run at 15–20 rpm to prevent peak bone compression necrosis.
• Final Insertion Torque: Recommended 35 to 45 Ncm insertion torque for immediate and delayed loading.

5. Restorative & Prosthetic Portfolio

• Straight & Angled (15°/25°) Abutments: Multiple gingival cuff heights (1, 2, 3, 4 mm) for individual crown restorations.
• Castable UCLA Abutments: Machined CoCr base with plastic burnout sleeve for custom laboratory screw-retained solutions.
• Multi-Unit Abutment (MUA) System: Straight and 17°/30° angled MUAs for screw-retained full-arch bridges and All-on-4 / All-on-6 rehabilitations.
• CAD/CAM Digital Workflow: PEEK and titanium scan bodies compatible with Exocad and 3Shape libraries, coupled with titanium bonding bases (Ti-Bases).

6. Primary Clinical Indications

• Universal implantology for single tooth, multi-unit bridges, and full-arch rehabilitations.
• Excellent in soft or compromised bone (D3/D4) requiring localized bone condensation.
• Immediate extraction socket placement (Type 1) and immediate restoration workflows.
• Clinicians seeking a reliable, universally recognized internal hex prosthetic interface.
