Smartgraft is a porcine xenograft supporting a vascularisation of the surgical site through its high porosity and large pores. The bone remodelling and volume stability are supported by the proprietary production process.

Description
Balance high porosity with stable volume remodelling
Cell adhesion
The rough surface of human-like porcine particles facilitates the attachment of new cells.1, 2
Rough surface, large pores, and high porosity enhance bone ingrowth.
Cell migration/infiltration
Facilitates vascularization and bone ingrowth.
Smartgraft’s high porosity and large pores enhance vascularization, bone ingrowth and osteointegration of the implant after surgery.
Smartgraft’s macropores range from 0.1mm to 1.0mm.
Native porous carbonate apatite possesses the natural pore structure for cell conduction.
Regeneration
Native porcine graft provides a human-like structure for balanced remodelling.9 The anorganic bone mineral matrix has interconnections that reduce the bulk density of the graft and allows for more void space for the growth of new bones.10
As a porcine-derived bone, Smartgraft accelerates alveolar bone healing as compared to Deproteinized Bovine Bone Mineral (DBBM).11, 12
The proprietary purifi cation process preserves carbonate apatite14, which has been shown to increase the bone forming activities of osteogenic cells and to enhance bioresorption of bone graft by osteoclasts.14-18
The biocompatibility is supported by the proprietary purifi cation process of the graft.19

Six reasons to add Hyadent BG to Smartgraft
Sticky bone can be prepared with this out-of-the box gel and Smartgraft in 3 minutes.
As hydrophilic agent, hyaluronic acid (HA) stabilizes blood clot and attracts growth factors to support and accelerate bone formation.20-23
HA supports angiogenesis.24
HA’s high molecular weight reduces swelling and discomfort while supporting scar-less healing.25
HA has natural bacteriostatic properties.26
HA’s special formulation remains present throughout the various phases of the healing process due to its slow degradation pattern (several weeks).22
Preparation of stable graft material:
Step 1
Place bone subtitute granules into a dish.
Hydrate using physiological solution or blood.
Remove any excess fluid.
Step 2
Add HYADENT BG to the hydrated bone substitution material.
Step 3
Mix using a spatula.
Repeat steps 2 & 3: Add additional HYADENT BG until the desired consistency is reached (ca. 2/3 Vol% graft material, 1/3 Vol% HYADENT BG).
Step 4
Keeping the putty at room temperature for 3-5 minutes may improve the consistency of the putty and make it slightly harder.
Step 5
Apply putty on to the defect.
Four reasons to use Smartbrane with Smartgraft
Smartbrane ensures adequate tensile strength to safely maintain bone graft stability and structure.27
Smartbrane is adaptable to bony surfaces without sticking to the graft or the instrument.31
Smartbrane has a resorption time of 8-12 weeks that can even be extended with Hyadent BG by several weeks.28,29
Smartbrane supports blood clotting and cell attachment.1,3,30
SMARTBRANE rehydrated: excellent adaptation to surfaces without sticking to graft or instrument.
