Immediate Implant Placement in a Patient With Osteoporosis Undergoing Bisphosphonate Therapy: 1-Year Preliminary Prospective Study.

The purposes of this preliminary study are to assess the risk of developing bisphosphonate-related osteonecrosis of the jaw (BRONJ) in a patient with osteoporosis using zoledronic acid and to report the results of a 1-year prospective clinical study regarding 5 immediately inserted implants in the anterior mandible. For this comparative prospective study, 24 female patients, aged ≥54 years, were chosen, all with partially edentulous mandibles. Group A consisted of 12 patients with osteoporosis taking zoledronic acid receiving a once-yearly intravenous infusion of zoledronic acid (5 mg).

Fixed bicortical screw and blade implants as a non-standard solution to an edentulous (toothless) mandible.

Aim: This paper deals with the treatment of an atrophied toothless mandible with a fixing bridge carried by two nonstandard implant systems.

Methodology: Four bicortical screws were implanted into the frontal part of the mandible and one implant on each side was placed into the distal area of the mandible as a support for a fixing bridge.

Results: During the years 2002 - 2007 the authors placed a total of 256 bicortical screw and 84 blade implants.
