Cortoss - Technical Specifications - Chemistry & Characteristics
Chemistry
Reinforcing Components
Synthetic ceramic particles
- Increases direct bonding to bone
- Improves mechanical strength
Resin Composition
3 difunctional, crosslinked resins delivered as two mix-on-demand pastes
- A high degree of three-dimensional crosslinking signficantly increases mechanical strength
- Permits immediate weight bearing
- Reduces leaching of unreacted components
- Enhances working time
- Reduces waste and preparation time
Radiopacity
Outstanding inherent radiopacity, for optimal fluoroscopic imaging as used in minimally invasive procedures
Set Time And Temperature
Set Time
- Products such as PMMA, with complicated mixing and handling procedures, require extended set times
- Mix-on demand delivery of Cortoss® facilitates fast, easy handling, negating the need for longer setting times
- Cortoss® sets (3-5 minutes) in less than half the time of PMMA
- Cortoss® setting time is temperature-dependant, and decreases as site temperature increases
Thermal Properties
- Lower exotherm temperature minimizes tissue necrosis
- The maximum exothermic temperature of Cortoss® is 28% lower than that of PMMA (typically 55-65ºC vs. 90-120ºC respectively)
- Cortoss® attains peak exotherm for less than 1 minute of the time where as PMMA remains above 51ºC for up to 8 minutes
