High demands are placed on every membrane in the field of GTR/GBR.
Primarily, these include biocompatibility, integration into the surrounding tissue, intraoperative handling, as well as duration of the barrier function. Resorba® membranes meet these requirements in an ideal manner.
Resodont® contains 2.8mg equine, native collagen fibrils per square centimetre. Parasorb Resodont® is preferably used for delicate procedures.
clinical application of Resodont® Membranes
The membrane is used in dental and in oral and maxillofacial surgery, mainly in guided bone regeneration (GBR) to cover defects and to secure augmentation material.
The area includes local augmentation before or during the insertion of endosteal implants, covering the facial maxillary sinus mucosa in sinus lift operations and covering alveoli after extractions...
...The wound healing process occurred without any infection or foreign body reactions, and, in all cases to date, the barrier function has been adequate for unimpaired bony consolidation.
If the membrane is exposed due to dehisences, immediate removal is not indicated, as consistent disinfectant irrigation treatment can achieve secondary epithelisation of the membrane without disturbing the underlying augmentation."

Bioequivalence study of two collagen membranes as part of dento-alveolar Guided Bone Regeneration (GBR)
Introduction: A number of collagen membranes with different manufacturing processes are available in the field of GBR. The aim of this study was the evaluation and comparison of two different membranes (PARASORB RESODONT®, Resorba, Nuremberg, Germany and Bio-Gide®, Geistlich, Wolhusen, Switzerland) in clinical use.
Summary and Final Assessment: Both membranes represent a safe and reliable solution for covering grafts in selected indication as part of GBR. The membranes can be well adapted to the desired shape and size, application and adaptation in the wound area do not present problems. In dry condition, both membranes tend to stick to wet gloves and should therefore only be handled and processed with instruments.
Wetting outside the wound appears sensible to avoid tearing of the dry membranes during intra-oral adaptation. In wetted version, both membranes can be well adapted to any anatomical situation. Additional fixation with sutures or pins does not seem necessary as both membranes adapt tightly to the underlying graft after wetting and dislocations hardly occur. So far no membrane-associated changes such as dehiscence, bacterial infection, swelling or reactions to foreign matter have been observed during the postoperative process, wound healing was primary in most cases.
Based on the observations and experiences made, there is no principal difference between the two membranes.
