collacone® - resorbable, natural collagen wound dressing cone


Natural collagen cone
collacone® is a wet-stable and moldable cone made of natural collagen. As a completely resorbable and hemostatic wound coverage, it is intended for the application in fresh extraction sockets in the daily clinical practice.
  • Closure of extraction sites
  • Biopsy sites
  • Minor oral wounds
  • Control and stop of bleeding
    in extraction sockets or
    biopsy sites
  • Internal sinus lift

Application and shaping

After opening the package, the collacone® is taken out with dry sterile instruments, placed and lightly pressed onto the cleaned wound with swabs. The collacone® can easily be cut to the necessary size with a sterile pair of scissors.


Generally, dry application of collacone® is recommended, since soaking or moistening the cone prior to implantation may impair its hemostatic properties. At the defect site the fleece rapidly soaks up blood. The collacone® maintains integrity in the presence of blood and during application.


At contact with the wet wound surface, the collacone® sticks to the wound and forms a gel like bond with the blood. Fixation by cross- or holding sutures could help keeping the cone in place when applied in extraction sockets.


In case of a dehiscence the wound usually heals without complications by granulation tissue formation and free contraction.

After tooth removal, the healing of an extraction socket requires the formation and maturation of a blood clot, followed by the infiltration of fibroblasts that replace the coagulum; finally, the application of a provisional matrix allows the formation of new bone tissue. The spongy structure of collacone® ensures an easy and fast application in extraction sockets. Notably, the structure of the cone is maintained after insertion into the defect.
