FAQ βioResorb® Macro Pore

What is βioResorb Macro Pore made from?βioResorb Macro Pore is made from 99% pure-phase Beta Tri-Calcium Phosphate (β-TCP). Each batch of product is tested via X-ray diffraction to ensure its purity. In addition, the calcium/phosphor atom ratio in βioResorb is 1.5 (very similar to the mineral phase of human bone which is 1.6).

What distinguishes this product from other synthetic (Alloplast) grafting materials?βioResorb has been specifically designed to fully resorb unlike many other ceramics- based grafting materials which may only be partially resorbable. Furthermore, βioResorb has been engineered to have both a micro and macro porous structure which results in a high percentage of interconnecting-porosity and mimics the structure of human bone. This interconnecting porosity allows for the vascularization and transport of cells throughout the graft material.

What distinguishes this product from biologically derived graft materials (i.e. Allograft and Xenograft)?Unlike biologically derived graft materials, βioResorb does not run the risk of disease transmission and/or immunologic reactions. In addition, being a synthetically derived product, it does not raise ethical or religious concerns with patients.

What is the mechanism by which βioResorb Macro Pore promotes new bone growth?βioResorb is an osteoconductive graft material that has been made with micro and macro porous structure. The macro pores range from 50-700μm and offer the optimal environment for vascularization and bony infiltration. Meanwhile, the micro pores range from 0.5-10μm which increases the surface area where new bone can form and allows for increased circulation of fluids throughout the graft site. Furthermore, β-TCP is osteotropic due to it’s high calcium ion composition.

FAQ βioResorb® Macro Pore

What sizes of βioResorb Macro Pore would you recommend for the following indications?

200-500μm Ideal for periodontal bone defects, grafting small extraction sockets, and packing around implants

500-1000μm Ideal for small to intermediate size cysts and grafting alveolar defects, and larger sockets

1000-2000μm Is intended for large cysts, sinus elevations and ridge augmentations

1400-3200μm Is intended for large cysts, sinus elevations and ridge augmentations

Note: table should be used only as guideline as defects vary in size and need. However, as a general rule of thumb, larger defects should utilize larger sized particles.

How long does it take for βioResorb Macro Pore to resorb and be replaced with new bone?βioResorb works via creeping substitution. That is, βioResorb resorbs simultaneously with the formation of new bone within the graft site. This method of substitution insures that βioResorb is maintaining space and providing an osteoconductive scaffold throughout the course of the grafting procedure. Typically, βioResorb Macro Pore is fully resorbed within 9-12 months. However, resorbtion rates can vary depending on a number of factors including particle size, defect size, and regenerative dynamics of the patient.

Is βioResorb Macro Pore radiopaque?Yes, which allows the clinician to easily monitor the progress of the turn-over of the βioResorb material.

What is the recommended preparation method for βioResorb Macro Pore?Although the Instruction For Use (IFU) say you can hydrate βioResorb with sterile isotonic saline solution, it is highly recommended that the βioResorb be mixed with the patient’s own blood whenever possible. βioResorb Macro Pore is extremely hydrophilic which results in a very cohesive and easy to handle material after it has been hydrated.
