Guided Bone Regeneration (GBR) is a well-established surgical technique used to stimulate new bone growth in areas with insufficient volume—most commonly in preparation for dental implants. The technique involves the use of a bone graft to fill the defect and a barrier membrane to isolate the graft site, preventing soft tissue infiltration and allowing uninterrupted bone formation.
When executed correctly, GBR can restore both form and function in the jaw, enabling long-term implant stability and superior aesthetic results.
Why Combine a Bone Graft and Membrane?
Successful GBR depends on two key elements:
- A high-quality bone graft that supports new bone growth
- A resorbable collagen membrane that protects the site while allowing natural healing
This combination creates an environment conducive to cellular migration, vascularization, and osteogenesis, essential components for predictable regeneration. The synergy between the graft and the membrane is critical for clinical success.
Xenobone®: The Foundation for Bone Regrowth
Xenobone® is a collagen-based bone graft derived from ultra-pure Type-I bovine collagen. It offers both osteoconductive and osteoinductive capabilities, which means it not only serves as a scaffold but also actively encourages the recruitment and differentiation of bone-forming cells.
Its microporous structure promotes:
- Effective blood clot stabilization
- Vascular infiltration
- Bone matrix deposition
Xenobone® is ideal for:
- Ridge augmentation
- Sinus lift procedures
- Socket preservation
- Peri-implant defect repair
Its availability in various granule sizes allows for precision in adapting to defect morphology, making it a versatile tool in any surgeon’s arsenal for guided bone regeneration.
Coll-os®: The Protective Barrier for GBR
Coll-os® is a resorbable collagen membrane made from more than 95% pure Type-I bovine collagen. It is designed to shield the bone graft from soft tissue invasion while facilitating proper wound stabilization and healing.
Key features of Coll-os® include:
- Dual-sided membrane for anatomical flexibility
- High tensile strength for secure placement
- Full bioresorption—no second surgery needed
- Can be used with or without sutures
When used in guided bone regeneration, Coll-os® helps maintain the integrity of the grafted site and ensures that only osteogenic cells populate the defect.
Clinical Benefits of the Xenobone® + Coll-os® Protocol
Dentists and oral surgeons who incorporate both materials into their GBR cases benefit from:
- Faster and more reliable bone formation
- Enhanced soft tissue healing
- Lower complication rates
- Improved handling and surgical efficiency
- Greater predictability in implant planning
Using Xenobone® as the scaffold and Coll-os® as the protective membrane forms a comprehensive biological solution that aligns with current best practices in regenerative dentistry.
Experience and Results
Clinicians consistently report positive outcomes using the Xenobone® + Coll-os® combination in:
- Horizontal and vertical ridge augmentations
- Complex sinus lifts
- Large extraction site preservations
- Immediate implant placement with bone grafting
The ease of handling, natural integration, and CE-certified quality give dental professionals the confidence to take on even the most challenging GBR cases.
Why Trust This Combination?
Developed by DESU Medical, both Xenobone® and Coll-os® are produced in ISO-certified cleanrooms and subjected to rigorous quality control standards. The materials are clinically validated, biologically safe, and globally trusted in dental regenerative procedures.
For clinicians aiming for long-term treatment success, the combined use of these two collagen-based biomaterials offers a reliable, effective, and biologically sound approach to guided bone regeneration.
