Phosphocalcic substitute for bone grafting

Presentation and indications

The GRAFTEK® HP is a highly porous synthetic bone substitute conceived for bone defect filling or reconstruction in dental and maxillofacial surgery. The GRAFTEK® HP is highly recommended in periodontology and implantology.

Instructions for use

Step 1

graftek4

Firmly hold the blister in one hand and, as you incline it in order to avoid any granule loss, slowly peel off the seal with the other hand.

Step 2

graftek5

Mix the GRAFTEK® HP granules with the patient’s blood sample, a saline solution or distilled water.
It is advisable not to excessively humidify the granules. Any liquid surplus should be absorbed with a sterile sponge.

Step 3

graftek6
Use a sterile spatula to mix the GRAFTEK® HP with the solution.
The humidified granules can be placed into the surgical site using a curved tool.

Step 4

graftek7

Gently fill each defect up to the highest level of the bone cavity, without excessive compression.
Osseointegration will be improved if blood and vessels can be penetrate the granules.

Step 5

graftek8

After placing GRAFTEK® HP granules in situ, the soft tissue flaps should be completely closed and tightly sutured, avoiding any tension.
A membrane can also be used to ensure the complete closure.




GRAFTEK HP benefits

High 90% porosity

During the GRAFTEK® HP bone remodeling process, the bone cells will be splitting up and digesting the biomaterial while producing the new bone replacement tissue. The high porosity minimizes the quantity of biomaterial to 10% compared to its global volume. The transformation process is thus faster and cells can progress more easily.

Fully synthetic

The GRAFTEK® HP does not pose any immune or infectious risk. This 100% synthetic product belongs to the calcium prosphate family and avoids any cross-contamination risk. Tricalcium phosphate is a bioactive calcium phosphate salt, more soluble in biological environment than hydroxyapatite and close to the mineral phase of human bone. The chemical formula of tricalcium phosphate is: Ca3(PO4)2

Biocompatible, osseointegrated then reabsorbed

Biocompatible, the GRAFTEK® HP does not present any complication during bone formation. On the contrary, the GRAFTEK® HP, osteoconductive, naturally maintains the bone volume and guides the bone neoformation. Placed in contact with the bone, the ß-TCP is rapidly osseointegrated and reabsorbed (on average: 6 to 7 months)

Granules morphology

The shape of the GRAFTEK® HP grains solves the problems related to the filling of irregular-shaped cavities. As the TCP grains are radio-opaque, the cavities filling and the graft integration can be radiologically monitored.

Simplification of the surgery:

The use of the GRAFTEK® HP reduces the need for autologous bone sampling (and thus the risks associated), the duration of the intervention and the surgical costs.

Expert in court


“Maxillary posterior edentulism is often associated to a low sinus floor, requiring, as a pre-implant therapy, its elevation through a sinus lift technique combined with autologous or synthetic bone grafting. The autologous bone has been considered for a long time as the best bone regeneration material. The drawbacks of the autologous graft are the medium densification of the graft and the significant loss of cell vitality of the grafted particles. The other approach is the use of biomaterials. Xenografts, mainly of bovine origin, have a variable and sometimes uncomplete resorption High porosity ß-TCP is a bone substitute with a macroporosity which is essential to bone regeneration since it determines the penetration of vascular and cellular elements. The choice of ß-TCP HP is based on its biocompatibility, its osteoconductive properties, its resorbability and its ability to maintain bone volume. The use of ß-TCP HP presents many benefits leading to the elimination of the risks associated with autogenous grafts and the reduction of the operating time and costs”
