Reliable synthetic graft with excellent osteo-conduction and gradual resorption

Q-Oss+

How do you benefit from Q-Oss+?

Q-Oss+ is Osstem’s synthetic bone graft material designed to support bone regeneration in implant and periodontal surgery. With a composition of 20% Hydroxyapatite (HA) and 80% Beta-Tricalcium Phosphate (β-TCP), it combines stability with controlled resorption. Its porous, interconnected microstructure promotes vascularization and osteogenic cell migration, ensuring effective osteo-conduction and natural bone replacement over time.

Available in multiple particle sizes (0.5–1.0 mm, 1.0–2.0 mm) and volumes (0.1 g to 2.0 g), Q-Oss+ provides flexibility to meet diverse clinical indications.

Why It Matters for Clinicians

Synthetic grafts are an important alternative to xenografts or autografts, offering consistency, safety, and availability. Osstem Q-Oss+ provides clinicians with a predictable, osteoconductive scaffold that gradually resorbs while being replaced by natural bone. Its balance of HA and β-TCP ensures stability where needed, while still allowing for remodeling—making it a trusted option for sinus lifts, socket preservation, ridge augmentation, and periodontal defects.

Key benefits

  • Balanced Composition
    20% HA for volume stability, 80% β-TCP for controlled resorption
  • Porous Microstructure
    Interconnected pores enable vascular ingrowth and bone regeneration
  • Gradual Absorption
    Resorbs predictably, supporting long-term bone replacement
  • Excellent Osteo-Conduction
    Reliable scaffold for new bone formation
  • Clinical Flexibility
    Available in multiple particle sizes and volumes for tailored application
Immediately after grafting
Osteogenesis

From graft placement to new bone formation

  • Immediately after grafting, Q-Oss+ supports the defect site by integrating with the fibrin network and blood cells
  • During osteogenesis, Q-Oss+ is gradually resorbed as new bone forms and matures around the grafted area
Pore Structure: Macropores & micropores
Blood Permeability: Q-Oss+ 1.0cc, contains 1.0cc of blood

Outstanding pore structure and blood wettability

  • Inter-connected micropores create high specific surface area (mean 2.0 m²/g)
  • Outstanding blood permeability and osteoblasts in blood lead to osteogenesis
Bone Replacement (Micro-CT)
Osteogenesis

Effective bone formation in implant procedures

  • Q-Oss+ is gradually disintegrated / absorbed during the period of new bone formation
  • Appropriate for implant surgeries and posterior areas where bone replacement is required
3 to 7: Low osteogenesis
10 to 0: Unstable volume maintenance
8 to 2: High osteogenesis and stable volume maintenance

Optimal composition for osteogenesis

  • Q-Oss+ is composed of β-TCP 80% + HA 20%, which is the optimal composition for osteogenesis
