COLL-OS Collagen Barrier Membrane is a resorbable collagen-based membrane developed specifically for dental and oral surgical procedures. Manufactured from ultra-pure Type I bovine collagen, it offers high biocompatibility, natural healing support, and a reliable barrier function. The membrane is designed to act as a temporary barrier that supports guided bone regeneration (GBR) and guided tissue regeneration (GTR). Its structural integrity and handling characteristics make it an ideal solution for clinicians aiming to enhance surgical outcomes. COLL-OS helps protect graft sites and promote natural tissue integration without the need for a second procedure.

In guided bone regeneration, COLL-OS is used to prevent soft tissue ingrowth into the bone graft area, allowing undisturbed osteogenesis. This is especially critical in implant preparation or ridge augmentation where space maintenance is essential. The membrane provides a stable environment for the graft material to mature and integrate. Because it is fully resorbable, no secondary surgery is needed for removal. It gradually degrades within 8–12 weeks as the natural tissue heals.

In periodontal regeneration, COLL-OS serves as a physical barrier between the gingival epithelium and the defect site. This promotes the regrowth of periodontal ligament, alveolar bone, and connective tissue in cases of intrabony defects. It helps maintain space for new attachment while protecting the wound area. Its natural collagen composition also supports cellular migration and tissue remodeling. This leads to improved clinical outcomes in GTR procedures.

The membrane is also highly effective in post-extraction socket preservation procedures. After tooth removal, COLL-OS can be placed over bone grafts or directly into the socket to protect the clot and guide soft tissue healing. It helps maintain the alveolar ridge dimensions and reduces the risk of tissue collapse. Its hemostatic effect supports clot stabilization and wound control. This improves the predictability of future implant placement.

In sinus lift procedures, COLL-OS may be used to line the Schneiderian membrane or cover the lateral access window. Its pliable yet durable nature allows easy adaptation without tearing. It helps reduce the risk of sinus membrane perforation and maintains the position of graft materials. The membrane’s collagen composition encourages mucosal healing. As it resorbs, it leaves behind a regenerated, stable graft zone suitable for implant insertion.

COLL-OS offers excellent handling properties, which make it easy to trim, position, and adapt to complex anatomical areas. It does not require pre-wetting or chemical treatment prior to placement. The membrane adheres well to moist tissues and can be used in either dry or hydrated form. Its tensile strength supports suturing if fixation is needed, but in many cases, flap closure alone is sufficient. The product is packaged sterile and ready to use.

The resorption profile of COLL-OS allows it to function as a protective barrier for 4–6 weeks, depending on the surgical site and patient healing response. Complete resorption occurs over approximately 2–3 months, supporting long-term tissue regeneration. It leaves no chemical residue or fibrous encapsulation behind. COLL-OS has been sterilized with gamma radiation and tested according to ISO standards for biocompatibility. Its safety profile makes it a reliable choice for both routine and advanced procedures.

COLL-OS is an effective, natural collagen membrane designed to meet the needs of dental professionals performing bone regeneration and soft tissue procedures. It supports predictable healing, simplifies surgical protocols, and reduces patient discomfort by eliminating the need for membrane retrieval. With its versatility and clinical reliability, COLL-OS fits seamlessly into modern regenerative dental workflows. For clinicians seeking a safe, efficient, and biologically active solution, COLL-OS offers exceptional value. It is available in multiple sizes and formats to accommodate different surgical needs.
