CRITERIA FEATURE BENEFIT
Formulation Ca10-x(M)x(PO4)6-x(HPO4,CO3)x(OH)2-x
[(M)=metal ions (e.g. Mg++)]• Mimics chemical structure of natural bone• Facilitates remodeling
Working Time 15 minutes in the OR• Provides long working time before implantation• Maintains “paste” form throughout
Handling, Mixing Readily mixes in AccuMix® Syringe• User friendly• No loss of BSM during mix or transfer• Can be mixed with blood or saline
Injectability Injectable under low pressure;no phase separation
• Requires only digital pressure to inject
Flowability Flows uniformly; no phase separationinto cancellous bone
• No need for surgical void creation, preserves healthy bone• Allows for complete defect fi ll
Irrigatability Hydrophilic; soluble in synovial fl uid • Irrigates easily if extravasation into joint space occurs
Setting Time Endothermically sets in 10 minutes at 37°C• Sets hard after closure• No thermal necrosis
Porosity 65% total porosity (interconnected); 1-300 µm• High surface area facilitates remodeling and bony ingrowth• Facilitates fl uid transfer through the material
Crystalline Structure Amorphous, nanocrystalline; 6 µm average size
• Mimics natural cancellous bone• Supports normal bone metabolism and remodeling
Compressive Strength ~10 MPa • Properties comparable to cancellous bone*
Bioactivity Interdigitates in bone; osteoconductive• Sets hard and maintains shape• Provides continuous osteoconductive scaffold
Remodeling Cell-mediated remodeling • Remodels with new bone growth
Drillability Drillable during and after setting • Procedural fl exibility
