Purpose

Dental implants (screws for fastening false teeth) have been coated with bisphosphonates (drugs that slow down removal of bone). Patients get one such screw and one without coating, by a surgeon who does not know which is which. The screws are compared by measuring how well fixed they are by a vibration measuring technique, and x-rays. The hypothesis is that the bisphosphonates will improve fixation.

Primary Outcome Measures:

Increase in resonance vibration frequency (ISQ units) from insertion to abutment connection as compared to the control in the same patient. [ Time Frame: 6 months ] [ Designated as safety issue: No ]

Secondary Outcome Measures:

Marginal resorption on x-rays [ Time Frame: 1 year ] [ Designated as safety issue: Yes ]

Estimated Enrollment:	16
Study Start Date:	October 2008

Arms	Assigned Interventions
Bisphosphonate-coated implant with internal control Each patient receives two implants at the same time: one bisphosphonate-coated and one uncoated control. Thus each patients has an internal control.	Device: Dental implant coating with a fibrinogen carrier for pamidronate and ibandronate
