Bisphosphonate-coated Dental Implants

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.

Condition Intervention Phase
Edentatio (Toothlessness)
Device: Dental implant coating with a fibrinogen carrier for pamidronate and ibandronate
Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
