title: Placement of screw-type implants in the pterygomaxillary-pyramidal region: surgical procedure and preliminary results.
abstract: A surgical technique for the placement of titanium screw-type implants (Brånemark system) in the pterygomaxillary-pyramidal region is presented. The correct direction, location, and length of the implant is decided during surgery. Cylindric osteotomes are used as bone-site formers, thus minimizing the use of drills in bone preparation. This not only conserves bone, but greatly reduces the potential surgical risks, especially of hemorrhage.
