naturesQue ColTect P
Xenogeneic porcine barrier membrane
Assuming that the clinical requirements for a barrier membrane are satisfied, individual preferences for the handling properties play a major role in the choice of collagen membranes. The easy handling of naturesQue ColTect P enables diverse applications in therapeutic concepts that include the use of regenerative measures.

Structure, design, and stability
naturesQue ColTect P is manufactured from purified collagen-rich tissue. Using a gentle method, the collagen is minimally crosslinked to give the membrane a predictable resorption profile with maximum tissue tolerability. A crosslinked structure prevents premature enzymatic cleavage of the collagen fibers and gives
naturesQue ColTect P a reproducible and reliable barrier function that is adapted to the time profile of bone healing.
This produces a highly versatile and strong membrane with comfortable handling properties.
naturesQue ColTect P is made up of a layer of intact collagen fibers. The membrane is not side specific.
Requirements profile for a collagen membrane
Collagen membranes alone do not have sufficient mechanical stability to shape and protect defect contours. For this reason naturesQue ColTect P is used together with bone substitute materials such as naturesQue SemOss B or naturesQue MaxOss P.
The use of bone substitute materials creates a volumizing framework in the defect space that is used by the osteoblasts as a substrate for bone deposition.
A barrier membrane protects the spaces in the bone defect and prevents the ingrowth of soft tissues. The job of the membrane is to establish and maintain a barrier that is permeable to nutrients between the bone and soft tissue. The membrane also stabilizes the augmentation material by covering the bone defect. The barrier function of naturesQue ColTect P lasts about 3 months, which is sufficiently long to ensure adequate bone healing.
Handling and feel
The naturesQue ColTect P membrane can be applied wet or dry. The membrane is cut to size so that the piece overlaps the margin of the defect by about 2 mm. When dry, naturesQue ColTect P is a sturdy, stable membrane. Wetting the membrane with saline or blood makes naturesQue ColTect P flexible, enabling it to be adapted to the defect contours.
It is not usually necessary to fix naturesQue ColTect P because the membrane can be easily wetted and adheres to the bone walls. Nevertheless, naturesQue ColTect P can be repositioned should this be necessary. If needed, naturesQue ColTect P can be sutured or fixed with pins.
