Radiographic Examination of Dental Implants

Examine the bone density at the fixture sites and monitor marginal bone loss. With a good parallel radiograph, the marginal bone loss is measured using the fixture threads as reference.

The marginal bone loss can range from 1.0 to 1.5 mm vertically in the first year. The fit between the abutment and fixture is also checked. Fixture fractures should also be checked. After the first year, estimated bone loss per year is less than 0.05 – 0.1 mm and offers a predictable long term prognosis.

Radiographs are made at the time of abutment connection and restoration insertion. Follow up radiographs are made at 1, 3, 5, 7, 10, 15 and 20 year recall. After 20 year recall the radiographs are made every 5 years.
