Brånemark osseointegration. Prognosis and treatment rationale.

The treatment rationale is a balance between benefit and risk. Benefit relates to the improvements that can be made over known, conventional treatments. Risk has been described as being both surgical and prosthetic in nature. Prosthetic risk is not related to the implant predictability as much as it is related to the restorative predictability. In the final analysis, a sound treatment rationale must include substantial benefit, low surgical risk, and a prognosis based on high restorative predictability.
