Spiralock® is a superior fastening technology ideally suited for threaded joint applications subjected to heavy shock and vibration, extreme temperatures, long hours of strenuous operation, and millions of loading cycles. This proprietary internal thread form, used in orthopedics and the aerospace industry, is incorporated in all BioHorizons Implants and features a unique 30° wedge ramp at the root of the thread that locks the abutment screw securely to the implant, and spreads the load throughout the entire threaded connection.
The Spiralock® thread configuration provides numerous advantages over standard thread designs:
1. Superior resistance to dynamic loading
2. Improved joint integrity
3. More evenly distributed load
4. Consistent reusability
5. Elimination of secondary locking devices
A conventional abutment screw V-thread is axially loaded versus a Spiralock® thread form that distributes the load radially. This uniform thread loading reduces load and stress concentration at the first engaged thread, significantly increases the strength of the connection and prevents fatigue failure.
That is what distinguishes BioHorizons.
