FAQ Cytoplast® RTM Membranes

What are Cytoplast RTM Resorbable membrane made from?Cytoplast RTM membranes are made from a highly purified type 1 collagen that has been harvested from bovine Achilles tendon.

What is the difference between bovine derived collagen and porcine derived collagen?In general, there is little difference among type I collagen of various animal sources. For example, type I collagen derived from porcine tendon is homologous to type I collagen derived from bovine tendon.

What is the resorption time for Cytoplast RTM?26-38 weeks. This makes Cytoplast RTM membranes one of the longest lasting resorbable barrier membranes available on the market today.

Can Cytoplast RTM membranes be left exposed in the oral cavity?It is recommended that primary closure be obtained when using Cytoplast RTM membranes. Exposure of these membranes to the oral environment can lead to unpredictable resorption rates which can in turn lead to premature exposure of the graft site.

Can Cytoplast RTM membranes be cut to fit a graft site?Yes, these membranes can easily be trimmed to fit the graft site.

Which side of the membrane should face the graft site?Either side of the membrane may face the graft site which adds to their overall ease of use

What kind of flexibility does the Cytoplast RTM membranes have?These membranes have been designed to have handling characteristics that accommodate a wide range of clinical needs. That is, stiff enough to allow for easy placement and maintain space in a graft site, while also flexible enough to easily contour to a ridge.

FAQ Cytoplast® RTM Membranes

Are Cytoplast RTM membranes cell occlusive?Yes. The membranes multi layer construction prevents epithelial cell down growth while still having a macromolecular pore size that allows for vital nutrient transfer.

Can Cytoplast RTM membranes be sutured or tacked into place?Yes. Furthermore, due to the unique fiber orientation found in Cytoplast RTM membranes they have a much higher suturepull out resistance than some other brands of resorbable membranes.

Can unused portions of Cytoplast RTM membrane be re-used?No. The FDA clearly states that these devices are single use and may not be re-sterilized or re-used.

How does Cytoplast RTM membrane compare versus a collagen based wound dressing?Unlike Collagen would dressings Cytoplast RTM membranes were specifically designed for GTR and GBR applications and will maintain a barrier throughout the critical wound healing period. Whereas, collagen based wound dressings are intended to be used as hemostatic agents and in most cases have been designed to fully resorb within 1 week (potentially leaving the graft site exposed during the critical wound healing period).

The multi-layer construction allowing tissue integration in outer layer while preventing direct passage of bacteria and epithelial cells.

What is the shelf life from Cytoplast RTM?3 years from the date of manufacture. The expiration date is printed on the box and on each individual membrane pouch.
