Below is an FAQ for our Cytoflex Resorb membrane. Any additional questions? Please free to create a new topic with your question.
Which side of the Cytoflex® Resorb should face gingival tissue?
The side with the distinct diamond pattern embossing (large grating) should face the gingival tissue. The smoother side should face the bony defect or bone graft site. Note: In the inner package, the embossed layer faces the dentist. Does the Cytoflex Resorb require primary closure? Can it be left exposed?
Primary closure is achieved when you are able to bring the tissue together and suture. When this is impossible after a large extraction, the practitioner needs to approximate the tissue as much as possible. Whether a barrier membrane can be left exposed is highly dependent upon the practitioner’s skills, experience with the barrier material, the construct of the barrier membrane and the treatment protocol. Cytoflex Resorb is cleared for use in conjunction with primary closure. No clinical studies have been performed as if the membrane can be left exposed. If an early exposure does occur after primary closure, the barrier properties of this material can be much more forgiving due to its long resorption duration. Is Cytoflex Resorb membrane chemically similar to the membrane used in the Box technique( for vertical and horizontal ridge augmentation ) ?
The Box Technique was invented in November 2008 by Dr. Andrea Menoni; it is the first prosthetically guided bone regeneration technique aimed at fully restoring the lost bone volume by using resorbable polylactid acid absorbable materials. The Cytoflex Resorb membrane is chemically similar to the materials used in the Box technique, however, Cytoflex Resorb is thinner and more flexible than the material used in the Box technique. How stiff is the Cytoflex Resorb material?
Cytoflex Resorb is slightly stiffer than regular paper yet can be easily folded without any pre-soaking. What are the indications of Cytoflex® Resorb?
Cytoflex® Resorb was cleared by FDA for use as a space making barrier in the treatment of periodontal defects, including two or three wall bone defects, class II furcations, recession type defects, circumferential defects, and dehiscence defects associated with dental implants. What are the recommended closure techniques?
In general, a double layer closure, with a deep layer of horizontal mattress suture followed by a standard wound closure with interrupted suture is recommended. During primary closure, adequate flap release must be accomplished in order to achieve a tension-free closure. Closure should be maintained for at least two weeks after surgery. The use of long lasting monofilament suture is recommended to prevent premature loss of suture strength, which may lead to early membrane exposure during the initial 2-week healing period. Can Cytoflex® Resorb be trimmed to fit a variety of defect sizes?
The membrane may be cut to the desired configuration with scissors. To enhance stability and adequate protection of the space over the bony defect, the membrane should be trimmed to extend 2-3mm beyond the defect margins and to remain at least 1 mm from adjacent, uninvolved teeth. May screws or tacks be used to stabilize Cytoflex® Resorb membranes?
Cytoflex® Resorb can be fixated with surgical screws or tacks. Proper fixation may be used to prevent membrane perforation and/or early exposure. Is soaking required prior to administration?
Cytoflex® Resorb can be trimmed, shaped and administered without pre-soaking. Doctors may wet the membrane either with sterile saline or patient’s blood prior to administration.
