Our Technology


We’ve continuously developed our technique since the first surgery in 1990. Yesterday’s miracles are a reality today, and our OPRA™ Implant System solutions will constantly encourage you to reach new goals.

OPRA™ Implant System

The OPRA™ Implant System is a bone-anchored prostheses system based on osseointegration, where the prosthesis is directly attached to the bone and therefore avoids using a socket.

  • The system consists of three parts: an anchoring element (the Fixture) and a skin penetrating connection (the Abutment), secured with a screw (the Abutment Screw).
  • The unique design is designed to help protect the patient in an effort to avoid bone fractures from accidental loads.
  • The system has been used by hundreds of amputees since the world’s first surgery in 1990 and has been proven in multiple clinical studies.

e-OPRA™ Implant System

In January 2013, Dr Rickard Brånemark led the world’s first surgery where neuromuscular electrodes were permanently implanted in an amputee, connecting prostheses to the patient’s bone, nerves, and muscles.

The e-OPRA™ Implant System remains in clinical trials today and is not commercially available.
