The Science Behind Bone Graft Source Selection
In the field of oral bone filling materials, the raw material source directly determines a product's biological performance and clinical outcomes. PoroGraft® bone graft strictly selects natural porcine femoral metaphyseal cancellous bone as its raw material — a choice grounded in rigorous scientific evidence.
Why Porcine Femoral Metaphyseal Cancellous Bone?
The femoral metaphysis is one of the most precious skeletal sites in porcine bone — only 20-40g of wet femoral metaphyseal cancellous bone can be extracted from a single pig, making the raw material rare and valuable.
PoroGraft® selects this specific anatomical site based on the following key advantages:
More Intact Natural Microporous Structure
Porcine femoral metaphyseal cancellous bone possesses a natural three-dimensional interconnected trabecular pore structure highly similar to human cancellous bone. Medgen's gradient temperature-rising calcination process completely preserves this natural microporous architecture, providing an ideal three-dimensional scaffold for bone regeneration.
Rougher Microscopic Surface Area
Compared to bovine-derived bone filling materials, PoroGraft® particles have a microscopically rougher surface area. This characteristic facilitates vascular cell adhesion and migration, creating a more favorable microenvironment for neovascularization while promoting directed stem cell differentiation.
Higher Zinc and Magnesium Ion Content
The zinc and magnesium trace element content in porcine femoral metaphyseal cancellous bone is similar to and higher than that of human bone. These trace elements play important roles in bone metabolism — zinc participates in osteoblast proliferation and differentiation, while magnesium contributes to the bone mineralization process. The rich zinc and magnesium ion content further enhances PoroGraft®'s osteoinductive efficacy.
Efficient Induction and Promotion of Bone Regeneration
Leveraging these raw material advantages, PoroGraft® provides an ideal scaffold for bone regeneration while efficiently inducing and promoting new bone formation:
- Excellent osteoconductive performance: Natural porous structure guides new bone growth along the scaffold
- Outstanding hydrophilicity and clumping effect: Facilitating clinical handling and implantation
- High purity and crystallinity: Purity ≥95%, crystallinity ≥95%, providing stable and reliable structural performance
- High biocompatibility: Strict virus inactivation and immunogen removal processes, with no rejection reactions post-surgery
Stable Bone Formation in 3-6 Months
PoroGraft® demonstrates significant early osteogenic effects, achieving stable bone formation within 3-6 months with high bone density. New bone volume and bone density are superior to control groups, providing solid and reliable bone tissue support for dental implant restoration. The material is naturally absorbed by the body, requiring no secondary surgery for removal.
Clinical Applications
PoroGraft® is indicated for multiple oral bone defect repair scenarios, including extraction site preservation, alveolar ridge augmentation, maxillary sinus lift, peri-implant bone defect repair, and guided bone regeneration (GBR).
As China's first porcine-derived oral bone filling material, PoroGraft® leverages its natural biomimetic properties and high-efficiency osteogenic advantages to offer a new material choice for dental medicine.
