The percentage of micropores of an average size of 5 µm and the percentage of macropores with an average size of 500 µm is 30 volume percent each. The size interval of the micropores is 0.5 – 10 µm, and that of the macropores is 50 – 700 µm. The high porosity enhances an improved dynamic regeneration as compared to other bone augmentation materials. The homogenous structure of macro and micropores offers a high capillary function, and the considerably larger surface can be soaked with more blood particles and cells of osteogenous potential. The pore structure allows more room for vascularization than other augmentation materials and provides an improved nutrition of the regenerative material. The considerably larger surface offers more contact for cellular resorption, resulting in a shorter resorption time.

The interconnecting micropore system of the granules and especially the macropores are connected by a collagenous fiber network, along with sufficient blood vessels. The collagenous fibers function as guidance for the vessels as well as the newly formed bone, this stimulating the direct apposition of bone on the surfaces of the granules prior to the start of resorption. The macropores facilitate the ingrowth of bone into the material, the osteones grow into the upper layers of the bone augmentation material. The bone regeneration material Bioresorb Macro Pore is resorbed completely, simultaneously with new bone growth and allows an accelerated regeneration of the natural vital bone at the defect site.
The new ß-Tricalcium phosphate ceramic material has osteoconductive properties based on the micro and macroporous structure which enable bone defects which would normally not heal in a sufficient way, to regenerate well in good bone quality so that an immediate or a later implant insertion is possible.

Despite the high porosity, Bioresorb Macro Pore has an optimal improved stability and high resistance against abrasion. The phase-free purity provides a stable structure and homogenous resorption ability in time under physio.

> 99% phase-free ß-Tricalcium phosphate ceramics
A new generation of phase-free bioresorbable ß-Tricalcium phosphate ceramics was created by an innovative manufacturing process. The material consists of an interconnecting porosity system with macro and micro pores.
