🦷 Clinical Summary:

Title: Clinical feasibility and benefits of a tapered, sand-blasted, and acid-etched surfaced tissue-level dental implantJournal: International Journal of Implant Dentistry (2020)Implant: Stella® Implant (Shinhung) – equivalent to Luna (Evertis SI) except for abutment connection

📌 Purpose

To evaluate the long-term clinical outcomes of a tapered, S&E surface-treated tissue-level implant with double-thread design and conical sealing, placed in various clinical conditions.

🔍 Key Findings

✅ Implant Survival & Success

• 105 implants placed in 61 patients (mean age 63.7 years)

• 98.1% 5-year success rate, with only 2 failures (both in highly compromised posterior maxillary bone)

• 100% survival for 4.0mm and 4.5mm implants

✅ Design Benefits

• 1° tapered body and 2.5° apical taper ➜ excellent primary stability

• S&E (Sand-blasted & Acid-etched) surface ➜ ~60% bone-to-implant contact

• Double-thread design (35° helix) ➜ faster insertion and improved stability

• Helix cutting edge ➜ self-tapping and minimal bone resistance

• 8° conical seal ➜ strong platform connection with minimal micromovement

✅ Marginal Bone Loss (MBL)

• Mean MBL at 5 years:▸ Mesial: 0.90 ± 0.61 mm▸ Distal: 0.74 ± 0.75 mm

• Well within accepted success thresholds (Albrektsson criteria: <1.5 mm in first year, <0.2 mm/year after)

✅ Diverse Case Feasibility

• Success seen in:

  • Posterior mandible and maxilla

  • Sinus graft sites

  • Osteoporotic patients

  • Sites with compromised bone quality

🌟 Clinical Implication for Luna® (Evertis SI) Implant

Even though the Stella® is a tissue-level system, its core structure (tapered body, S&E surface, double-thread, and apex design) is identical to Luna (Evertis SI). This study validates Luna's exceptional performance in the following ways:

🔹 1. Strong Primary Stability in All Bone Types

Thanks to the tapered body and helix cutting edge, Luna implants show secure initial fixation—even in soft or grafted bone.

🔹 2. Reliable Long-Term Bone Maintenance

The S&E surface of Luna promotes early osseointegration, contributing to minimal marginal bone loss over 5+ years.

🔹 3. Surgical Efficiency

Double-threaded body and self-tapping tip allow for rapid, predictable placement, reducing surgical time and trauma.

🔹 4. Versatility Across Challenging Cases

This study included elderly, medically compromised, and grafted cases, affirming Luna’s performance across all patient profiles.

🔹 5. Minimal Prosthetic Complication Risk

The conical seal ensures tight prosthetic connection and minimizes micro-gap issues, preserving peri-implant health.

🎯 What This Study Proves About Luna® (Evertis SI)

“Same Engine. Greater Access.”This study confirms that the implant core design of Luna® is clinically validated for predictable long-term success, even in compromised cases—without sacrificing surgical ease or biological outcomes.
