The One-Piece ACTIVE is Leader Medica’s solid monophasic implant system engineered in Italy where fixture and abutment form an unbroken monolithic titanium structure. By eliminating the mechanical implant-abutment interface, ACTIVE eradicates micro-gaps, bacterial percolation, dynamic micro-movements, and screw loosening complications entirely, making it the premier choice for immediate loading and minimally invasive single-stage workflows.

1. Monolithic Architecture & 3 Prosthetic Head Styles

• Zero Micro-Gap Integrity: Complete elimination of the retaining screw and micro-gap ensures an impenetrable biological barrier against bacterial colonization, preserving crestal bone height permanently.
• ACTIVE (Straight Post): Solid, prepable cylindrical abutment head that can be modified intraorally or extraorally for single cemented crowns and multi-unit fixed bridges.
• ACTIVE ESTHETIC (Angled 15°): Anatomically contoured pre-angled solid abutment for anterior axis correction and seamless emergence profile adaptation.
• ACTIVE O-RING (Ball Attachment): Integrated spherical ball head designed for tissue-supported, implant-retained removable overdentures, compatible with titanium retentive caps and multi-retention silicone rings.

2. Macro Geometry, Microthreading & Rounded Safe Apex

• Coronal Microthreading: Fine cervical micro-threads relieve peak crestal bone stresses while promoting cellular attachment and soft tissue sealing.
• Truncated-Cone Body Geometry: Easily conforms to narrow alveolar ridges and provides progressive lateral bone condensation in split-crest and sinus lift procedures.
• Variable Geometry Threads (High B.I.C.): Asymmetrical progressive coils maximize bone contact; a standard Ø 3.8 × 10 mm fixture develops 131 mm² of bone contact surface, enlarged by 43% through DAS® microroughness.
• Rounded Safe Apex: Spherical, atraumatic tip prevents perforation of the Schneiderian sinus membrane and protects the inferior alveolar nerve trunk.

3. Grade 4 Titanium & Bioactive DAS® Surface

• High-Strength Medical Grade 4 Titanium: Superior mechanical fatigue endurance and bending resistance, essential for slim diameters in narrow ridges.
• Alumina-Free Dual Acid Etch (DAS®): Pure subtractive chemical bath ( = 1.35,mu ext{m}$) free of embedded alumina abrasive grit.
• Argon-Oxygen Cold Plasma Glow-Discharge: Purges all hydrocarbon contaminants, imparting high surface wettability and rapid osteogenic stimulation.

4. Step-by-Step Surgical & Drilling Protocol

• Minimally Invasive Flapless Placement: Ideal for tissue punch or conservative flap protocols without secondary abutment connection surgery.
• Under-Preparation in Soft Bone: Slight under-drilling in D3/D4 trabecular bone to secure high primary stability and bone condensation.
• Insertion Torque for Immediate Loading: Recommended 35 to 50 Ncm insertion torque to support immediate provisionalization protocols.

5. Restorative & Clinical Workflow

• Direct Impression Coping: Snap-on plastic impression caps for conventional open/closed tray impressions or direct intraoral scanning.
• Intraoral Margin Preparation: Prepable with high-speed diamond burs with copious water spray just like a natural tooth abutment.
• O-RING Overdenture System: Complete prosthetic kit with titanium housings and color-coded retentive silicone rings (soft, medium, hard).

6. Primary Clinical Indications

• Immediate loading protocols with instant provisional restorations.
• Narrow alveolar ridges (less than 5 mm bone width).
• Ridge expansion and split-crest osteotomies.
• Minimally invasive overdentures in elderly patients requiring swift single-stage surgery.
