- A sterile, 30mm x 40mm resorbable barrier membrane derived from highly purified porcine pericardium designed to provide extended barrier protection and structural support for major oral and maxillofacial bone grafting procedures
Uses
- Large-Scale Guided Bone Regeneration (GBR):
- Simultaneous use with dental implant placement to manage complex bony voids
- Extensive Alveolar Ridge Reconstruction:
- Building up broad horizontal or vertical ridge deformities before or during prosthetic treatment
- Immediate or Delayed Socket Augmentation:
- Protecting expansive multi-rooted extraction sockets or neighboring, multi-tooth defect windows
- Dehiscence and Fenestration Repairs:
- Covering exposed implant threads or major bony defects spanning across multiple tooth roots
- Maxillary Sinus Windows:
- Sealing and protecting the Schneiderian membrane over large lateral window sinus elevations
Features
- Natural Pericardium Honeycomb Matrix:
- Retains the inherent multi-directional, fibrous architecture created by the continuous movement of the heart wall, offering natural tear resistance and elasticity
- Non-Cross-Linked Composition:
- Composed predominantly of purified Type I and Type III collagen microfibrils. It completely avoids chemical cross-linking agents, lowering the risk of local tissue irritation or rejection
- Extended ~24-Week Resorption Profile:
- Substantially resists premature breakdown, acting as a stable physical barrier for up to 6 months before safely degrading into carbon dioxide and water via endogenous enzymes
- Antigen-Free Processing:
- Thoroughly purified and sterilized to strip away cellular components, ensuring an exceptionally high level of biocompatibility without antigenic reactions
Benefits
- Dual-State Handling Adaptability:
- Can be customized and adapted in either a wet or dry state; when hydrated for ~5 minutes in sterile saline or blood, it becomes highly drapable and contours flawlessly over irregular ridge defects and when dry, its structural rigidity allows it to slide cleanly into tight spaces like lateral sinus windows
- High Structural Tensile Strength:
- Unlike traditional collagen sheets that easily tear, Collaflex is highly resilient, it easily accepts surgical bone tacks or tight suturing without tearing, ensuring the underlying bone matrix stays immobilized
- Rapid Angiogenesis & Cell Attachment:
- The natural porous micro-fleece structure serves as an optimized pathway for trans-membrane vascularization, accelerating the delivery of vital nutrients and cell attachment across the surgical flap
- Sausage Technique Compatibility:
- Its inherent toughness makes it a preferred material for advanced tension-grafting methods (such as the "sausage technique") to tightly clamp loose bone granules against host bone
