The IL® Nasal implant is Leader Medica’s cutting-edge fusion of bicortical nasal floor anchorage and the B.O.P.T.® convergent tissue-level collar. While the extended-length fixture secures rigid anchorage into the dense cortical floor of the nasal aperture, its convergent transmucosal collar provides the horizontal biological volume necessary for soft tissue thickening and stable pink esthetics in the severely resorbed anterior maxilla.

1. Unique Advantages of the B.O.P.T. Convergent Collar in Nasal Implants

• Horizontal Soft Tissue Thickening: In anterior maxillary atrophy, the overlying mucosa is typically thin. The convergent collar provides horizontal room for connective tissue fibers to thicken without crestal bone resorption.
• FMC® (Fibroblast Micro Channel) Microgrooves: Calibrated 50 µm microgrooves with biomimetic golden anodization to direct fibroblast adhesion, stimulate dense collagen bundles, and prevent apical epithelial migration.
• Supragingival Restorative Margin: Transmucosal design moves the restorative finish line away from the bone crest, preventing subgingival cement entrapment.

2. Bicortical Anchorage Mechanics

• Rigid Nasal Floor Engagement: Bi-cortical anchorage delivers insertion torques > 45 Ncm for immediate loading protocols.
• Bodyblade® Directional Flutes: Ensures trajectory fidelity when cutting into dense cortical bone plates.
• Straight Ahead Friction Connection: 0.5 mm friction collar lock maximizing joint stability under lateral incisal forces.

3. DAS® Surface & Argon-Oxygen Cold Plasma

• Dual-acid etched titanium ( = 1.35,mu ext{m}$) free of corundum sandblasting contaminants.
• Cold glow-discharge plasma decontaminates 100% of hydrocarbons and provides superhydrophilic cell attraction.
