SHELTER

SHELTER is a pericardium membrane of bovine origin and, thanks to the innovative Pericross decellularization system, the three-dimensional structure of collagen is maintained.

The multidirectional composition of the pericardial collagen fibers allows for greater stability and protection to the graft site.

At UBGEN we have developed two types of membranes:

  • SHELTER Fast, a membrane with a fast resorption time (4-5 weeks) thanks to the particular broad-textured collagen structure;
  • SHELTER Slow, a membrane with a slower resorption time (4-6 months) due to a modified three-dimensional structure of collagen fibres, that are more resistant because of intensified bonds.

SHELTER Fast and SHELTER Slow are occlusive to the passage of cells. They are designed to promote osteoblastic and periodontal ligament cells proliferation, protecting the site from soft tissue colonization; stable and resistant to traction they are easy and manageable in positioning.

Why to choose SHELTER

  1. Optimal clinical handling: Shelter adapts perfectly to the contours of the defect, does not stick to gloves or instruments;
  2. The multilayer structure makes it elastic and flexible;
  3. It can be used on both sides indifferently;
  4. It is particularly resistant to traction: it accepts a wide range of sutures and fastening systems;
  5. Supports neoangiogenesis;
  6. It has chemotactic capacity, the tissues heal quickly in case of post-op dehiscence;
  7. It has controlled resorption times.

Biocompatibility

Tabella 1

Table 1 - The cross-linking process of the Slow membrane allows the latter to be reabsorbed in a longer period of time (4-6 months) than the Fast; this is due to the greater number of intramolecular bonds between the collagen fibrils which confers a certain porosity after dehydration.

Table 2 - The stress-strain curves show a characteristic trend of collagenic materials and this confirms the fact that UBGEN production processes keep the structure of the collagen fibrils and other components such as elastin intact.
COMPUTERIZED MICROTOMOGRAPHY SHELTER MEMBRANE

The mechanical traction tests confirm that the Pericross production process maintains the exceptional resistance qualities of the intertwined collagen fibers and guarantees the natural three-dimensional structure of the material together with the chemotactic ability to attract fibroblasts.

SHELTER FAST

SHELTER Fast is the bovine pericardium membrane capable of resorbing quickly, 4-5 weeks.
