The Impact of Parathyroid Hormone (PTH) on Craniofacial Osseous Regeneration in Bone

• Status: Terminated
• Trial end date: 2015-11-01
• Target enrollment: 0
• Participant gender: All

Summary

Good bone healing and bone build-up are necessary for the success of dental implants. Research in animals and humans has shown that a drug, called Forteo, can increase bone build-up and bone strength over time. Forteo has been approved by the Food and Drug Administration (FDA) for use in patients with a condition where bone is broken down and weakened, called osteoporosis. The investigators do not know, however, whether Forteo is effective for use in humans for improving bone healing after implant placement, and whether it will have the same bone-building and bone-strengthening effects as for patients with osteoporosis. This research study is being done to learn what effect 7 weeks of treatment with Forteo will have on bone build-up and strengthening of bone for patients receiving implants.
