| Fourth-generation bones model natural cortical bone using a mixture of short glass fibers and epoxy resin pressure injected around a foam core. Standard bone models are manufactured with a solid rigid polyurethane foam cancellous core material, unless cellular rigid polyurethane foam is specified. The mid-shaft area has an intermedullarly canal.
Fourth-Generation Composite Bones Have Improved Properties
Fourth-generation composite cortical bone has been developed in order to meet the demanding needs of in vitro experiments, fatigue testing and to more closely simulate natural cortical bone. The result is a composite bone with enhancements to the following properties: - Fracture Toughness - Fatigue Crack Resistance
- Fatigue Life - Implant Subsidence
- Tensile Strength & Modulus - Compressive Strength & Modulus
- Thermal Stability - Moisture Resistance
No changes have been made to the anatomical structure of the bones.Information provided by Sawbones. |
