What is it indicated for?
Straumann MembraGel is a biodegradable, synthetic, in situ forming hydrogel material. It is intended to aid in the regeneration and integration of oral tissue components in guided bone regeneration procedures. This includes the surgical treatment of peni-implant defects, bone defects, deficient alveolar ridges, and extraction sockets. Because MembraGel is not self-supporting, it must be used in combination with a bone graft material in order to maintain space under the membrane.
Indications for use as stated in the FDA summary.
