Brief 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.

Study Arms (2)
Teriparatide
EXPERIMENTALdemeclocycline HCl (150 mg, four times per day for 3d) followed by a 12 day intermission then 3 more days of demeclocycline HCl (150 mg, four times per day). One day after the last demeclocycline dosage, subjects will be instructed to self-administer teriparatide (or placebo) for 7 weeks. Twenty-five days after the last demeclocycline dosage, subjects will begin their second set of tetracycline labels:(250 mg, four times per day) for three days, followed by 12 days off, and then repeat another 3 days of tetracycline HCl (250 mg, four times per day). On day of the last teriparatide (or placebo) injection, subjects will present for bone core removal and dental implant placement.
Control
PLACEBO COMPARATORdemeclocycline HCl (150 mg, four times per day for 3d) followed by a 12 day intermission then 3 more days of demeclocycline HCl (150 mg, four times per day). One day after the last demeclocycline dosage, subjects will be instructed to self-administer teriparatide (or placebo) for 7 weeks. Twenty-five days after the last demeclocycline dosage, subjects will begin their second set of tetracycline labels:(250 mg, four times per day) for three days, followed by 12 days off, and then repeat another 3 days of tetracycline HCl (250 mg, four times per day). On day of the last teriparatide (or placebo) injection, subjects will present for bone core removal and dental implant placement.
Interventions
20ug per day,via subcutaneous injection, for 7 weeks
