PerOssal® is used for permanent filling or reconstruction of bone defects in accident surgery, orthopedics, orthodontic and facial surgery.

PerOssal® is a newly developed synthetic bone replacement material with two outstanding properties. PerOssal® makes available a bone replacement material that after surgical cleaning of the wound can be inserted into even infected bone defects with a simultaneous delivery of antibiotics. This means that in the future, for example, it will be possible to select antibiotics to suit the patients microbiological results and to administer them individually. The second key property is that PerOssal® is rapidly, completely absorbable. Thus the defect can be filled quickly with new, autogenous bone and the patient can be spared a further operation to remove the implant. The PerOssal® component responsible for this, a nanocrystalline hydroxylapatite, is sold by aap mebio in Germany under the name Ostim®.

By linking bone replacement with local wound healing, PerOssal® offers physicians a specially tailored therapeutic concept for filling in bone defects in infected areas. The product is easy to handle and can be combined freely with different active ingredients. This makes it attractive for the user from an economic point of view, too.
