LASAK launches a highly effective Collagene AT® barrier membrane for guided tissue regeneration. It is used primarily together with a bone substitute material, such as OssaBase-HA and / or PORESORB-TCP. This collagen membrane is naturally resorbed, typically within 180 days, eliminating a second operation for its removal.
The Collagene AT® membrane is made of pure lyophilized hypoallergenic collagen of equine extraction.
Collagene AT® is a membrane with nanometric micro-irregularities at the surface that creates a barrier effect. Amongst the collagen layers with reticular links there are micro spaces of 10-20 microns to prevent cell migration.
This barrier effect prevents epithelial and soft connective tissue cells from interfering with bone growth or paradontal tissue growth. The maintenance of a space beneath the membrane allows osteoblast migration and new bone growth or new paradontal growth.
The membranes are fully resorbed within 180 days, therefore, eliminating the need for second surgery.
