The swedish system of osseointegrated implants: Problems and complications encountered during a 4-Year trial period

An account is given of the practical problems and complications encountered by and referred to the authors during the first 4 years of clinical use of the Brånemark system at the University of Washington. Most of the problems were iatrogenic and avoidable by careful planning, adherence to the recommended protocol, and the exercise of good judgment. No significant faults were found to be inherent in the system itself.
