The OSFE technique, without bone grafts, was found to produce predictable results in the treatment of 36 patients with restricted bone volume in the posterior part of the maxilla.

The OSFE technique, without bone grafts, was found to produce predictable results in the treatment of 36 patients with restricted bone volume in the posterior part of the maxilla.

The OSFE technique is a reliable method for rehabilitation of patients with atrophied posterior maxilla. However, the success of this method is associated with the amount of the residual bone. In the present study, this surgical approach without bone graft showed reliable long-term results with Astra implants.
