Imaging of dental implants in severely resorbed maxillae using detailed narrow-beam radiography. A methodological study

OBJECTIVE: To evaluate the accuracy of the detailed narrow-beam (DNB) technique with the Scanora multimodal X-ray unit for the assessment of dental implants in severely resorbed maxillae as an alternative to conventional intra-oral radiography. METHODS: The DNB technique was used in 15 consecutive patients with maxillary overdentures supported by implants in the canine regions. Both conventional intra-oral radiographs and DNB radiographs were also obtained for a further 15 consecutive patients with maxillary fixed prostheses on implants in the canine region. The marginal bone height was scored in relation to the threads on the implants. RESULTS: Intra-observer agreement was 95%. There was an 84% agreement between the two radiographic methods: the difference was at most one thread and was not significant (p = 0.43). CONCLUSIONS: The DNB technique is an accurate alternative when conventional intra-oral techniques cannot be used properly.
