DYNA-MBS

Medical Bone Screw

DYNA-MESS has developed a special servo-electric testing machine for testing metallic bone screws according to ASTM F543. 

With a nominal force of 1 kN and a displacement of 300 mm, various test modules can be realised:

Static torsion test

• Torque/Angle controlled test with predefined speed
• Adjustable fracture detection
• Determination of yield strength, max. torque, fracture angle
  
  Determination of screw torque

• Angle controlled turn in/out of bone screws with predefined speed under axial load
• Determination of the max. driving torque
  
  
  
  Pull-out test

• Angle controlled screwing in with predefined speed
• Displacement controlled pull-out with predefined speed
• Adjustable fracture detection
  
  Determination of self-tapping properties of self-tapping medical bone screws

• Angle controlled screwing in under increasing axial load
• Determination of the axial force at which the self-tapping effect begins
