Characteristics: Obtained from mesenchymal tissue (heterologous pericardium) the Evolution membrane is completely resorbable. Its structure is made of dense collagen fibers of high consistency and of extraordinary resistance that offer the specialist surgeon: - the maximum adaptability to bone tissue and soft tissues - an easy and secure suturability to nearby tissues - the best membrane/bone and membrane/periosteum interface - stability and prolonged protection of the underlying graft |
Handling: The membrane can be shaped with sterile scissors until the desired size is reached; it must then be rehydrated with lukewarm physiological solution. Once it acquires the desired plasticity, it must be adapted to the grafting site. N.B.: in case of accidental exposure, the dense collagenic matrix of Evolution protects the graft from infection; the membrane itself will also not be infected, allowing second intention healing. |
CLINICAL INDICATIONS SUMMARY Oral surgery and traumatology: the standard model is always recommended in case of large regenerations with risks of exposure. Implantology: ideal for covering antrostomy and for protection of two wall defects graft. Periodontology: protection of grafted intrabony defects when flaps suture presents risks of exposure (fine model); space making in gingival recessions (fine model). Besides an eutrophic effect, Evolution membranes provide grafting site stabilization as well as long lasting protection against external agents. |
CLINICAL INDICATIONS OVERVIEW Evolution is obtained from mesenchymal tissue (heterologous pericardium) and is completely resorbable. Experimental studies have shown histological evidence of the prolonged barrier effect of this membrane, which lasts at least eight weeks. The dense collagenic matrix of Evolution protects the graft from infection in case of accidental exposure: the membrane itself will also not be infected, allowing second intention healing. This property is particularly important in case of regeneration of large posterior sockets, when flaps cannot completely cover the graft. In lateral access sinus lift Evolution membranes are indicated to cover antrostomy (standard model) and to protect the sinus membrane from cutting risk due to graft pressure (fine model). Evolution is also ideal to protect peri-implant regenerations and periodontal grafts (fine model). Finally Evolution fine has been successfully used in combination with OsteoBiol Gel 40 for the treatment of gingival recessions. To order Gel 40, please contact us. |
NOTE: The reported values for resorption time are estimates and purely indicative: these values can therefore vary depending on the patient and grafting site.
