Bone regeneration, particularly in dental and orthopaedic applications, has always been a challenging field. The demand for innovative solutions to enhance healing and improve patient outcomes is ever-present. One such groundbreaking approach involves the use of SURGISPON® absorbable gelatin sponge, as a carrier for simvastatin. Though simvastatin is traditionally known for its cholesterol-lowering properties, recent research has unveiled its potential in bone regeneration. This blog delves into the innovative use of SURGISPON® and simvastatin in bone regeneration, emphasizing its clinical effectiveness and future potential.
Advancements in the Treatment of Periapical Defects
Periapical defects, often arising from untreated or inadequately managed dental infections, present a significant challenge in endodontic therapy. These defects lead to severe bone loss and frequently require surgical intervention combined with regenerative therapy. Traditional bone regenerative materials like Hydroxyapatite (HA) have yielded consistent results, yet the pursuit of more effective solutions persists. Notably, Simvastatin, known for its cholesterol-lowering capabilities, also possesses bone-regenerative properties. However, its direct application to bone tissue can provoke severe inflammatory reactions, complicating its use.
In the early days, periapical defects were primarily managed through drainage and basic pain management techniques. The discovery and introduction of antibiotics revolutionized dental care by effectively controlling infections. However, these treatments focused mainly on symptom management rather than addressing bone loss. Surgical techniques, such as apicoectomy and bone grafting using materials like HA, marked significant advancements but came with limitations, including invasiveness and complexity. Platelet-Rich Fibrin (PRF), while not a primary graft material, has been used adjunctively to enhance healing and bone regeneration.
By examining both the challenges and advancements in treating periapical defects, we can appreciate the ongoing evolution of endodontic therapies. The integration of innovative materials and techniques promises to enhance patient outcomes and streamline clinical procedures.
The Innovative Solution: SURGISPON® as a Drug Carrier
SURGISPON® Absorbable Haemostatic Gelatin Sponge (Aegis Lifesciences) is a quick and effective hemostatic agent that stops bleeding fast during surgical procedures. Its porous structure and excellent absorption capacity make it an ideal carrier for delivering therapeutic agents like simvastatin directly to the target site. When combined, SURGISPON® and simvastatin create a synergistic effect that enhances bone regeneration and accelerates healing processes.
Why Choose SURGISPON®
The success of this approach relies on the unique properties of SURGISPON® [2]:
- Rapid Hemostasis: It provides secure and speedy hemostasis, effectively controlling bleeding.
- Biocompatibility: SURGISPON® well-tolerated by tissues, minimizing the risk of adverse reactions.
- Sustained Release: The gelatin sponge structure ensures a gradual release of simvastatin, enhancing its therapeutic effects over time.
- Ease of Use: The sponge is easy to handle and mold into the required shape, making it ideal for precise applications.
- High Absorption Capacity: It can absorb approximately 45 times its own weight in blood.
- Saves Surgical Time: The use of SURGISPON® significantly reduces the time required for surgical procedures.
- Faster Recovery: It minimizes postoperative time and accelerates recovery for patients.
Clinical Analysis
A pivotal study conducted by Gupta et al. (2020) evaluated the effectiveness of HA, PRF simvastatin with gelatin sponge (SURGISPON®) in bone regeneration of periapical defects in 39 patients. In this study, simvastatin powder along with gelatin sponge (SURGISPON®), moistened with 2 ml of normal saline solution. This mixture was then carefully grafted into the bone defect, ensuring not to disturb the MTA retro-filling. The flap was subsequently sutured, and the procedure continued smoothly without complications.
The outcomes were assessed over a 12-month period using clinical and radiographic analyses:
- Superior Bone Regeneration: The simvastatin group showed a significant improvement in CBCT-Periapical Index (PAI) scores at both the 6th and 12th-month follow-up compared to the HA and PRF groups. This indicates a faster and more effective bone regeneration process as shown in 1.
- Enhanced Healing: Patients treated with simvastatin group experienced no postoperative symptoms and showed an accelerated rate of healing as compared to HA and PRF group.
- Statistical Significance: The simvastatin group significantly outperformed the HA and PRF groups in terms of bone regeneration, underscoring the potential of this approach.

Advantages Over Traditional Methods
- Reduced Side Effects: Traditional treatments involve systemic medications with potential side effects. SURGISPON® and simvastatin minimize systemic exposure and reduce side effects.
- Direct Bone Regeneration: Traditional methods manage symptoms but don’t promote bone regeneration. SURGISPON® and simvastatin actively stimulate bone healing.
- Enhanced Effectiveness: Traditional treatments have limitations in promoting lasting healing. The innovative method offers targeted, effective bone regeneration.
Future Directions in Bone Regeneration
The integration of simvastatin with SURGISPON® offers a novel and effective solution for managing periapical defects and other bone-related conditions. This combination can be used in various dental and orthopaedic surgeries to enhance bone healing and regeneration. Future research may further optimize dosages, delivery methods, and explore its potential in other medical fields, promising a significant advancement in regenerative medicine.
To further maximize the bone-regenerative effects of simvastatin, innovative delivery methods such as hydrogel carriers and polymeric scaffolds provide structural support and sustained release [3, 4] while nanoparticles and liposomes offer precise control over release kinetics and targeted delivery [5]. Additionally, microspheres made from biocompatible polymers ensure sustained release, promoting effective bone regeneration [6].
Conclusion
The innovative use of SURGISPON® as a carrier for simvastatin represents a significant breakthrough in bone regeneration therapies. This approach offers clinicians a powerful tool to improve patient outcomes, providing faster recovery times and more effective treatments. By facilitating the controlled release of simvastatin, SURGISPON® enhances its bone anabolic properties while minimizing potential risks. As research continues to evolve, the potential applications of this technique are vast, promising a new era in regenerative medicine and improved patient care.
