Graftys Quickset™
Quickset calcium phosphate cement* is a macroporous, injectable, hardening and resorbable bone filler provided in an easy-to-use, closed mixing system.
Composition:
The mixing system is a dual-chambered syringe containing a powder and mixing liquid.
The powder chamber contains a mixture of calcium phosphates and an organic polysaccharide polymer; the polysaccharide is a highly biocompatible polymer that optimizes the viscosity, cohesiveness, and macroporosity.
- The mixing liquid consists of a sodium phosphate solution which facilitates the setting time (crystallization) of the cement
- The end product is a calcium-deficient apatite very similar to the mineral phase of bone Physical and Chemical Properties
- Global porosity of 70% • Microporosity (<10 µm): 88% • Mesoporosity (10-100 µm): 2% • Macroporosity (>100 µm): 10%
- Porosity is present by the time it reaches complete hardening (24 hours after implantation)
- Mechanical compressive strength of 24 MPa (24 hours after implantation)
- Excellent cohesiveness, which prevents washout by biological fluids
- No shrinkage during crystallization
- Nonexothermic reaction
- Radiopaque
