Bone loss at implants and teeth in the same inter-proximal unit: A radiographic study.

Article Abstract

Objective: This study was performed to determine whether the distance between an implant and a tooth present in an inter-proximal unit influenced the amount of marginal bone loss that occurred at the two facing (adjacent) surfaces.

Materials And Methods: One hundred and eighty patients with a total of 278 inter-proximal units were included. Radiographs of implants that also included adjacent (facing) natural tooth/teeth were digitalized, and various linear measurements were performed using a software program. The marginal bone level and the bone level change that had occurred during a mean of 5.8 years were assessed as well as distance between the implant and the adjacent tooth/teeth.

Results: The mean amount of additional marginal bone loss that took place during the observation period was about 0.4 mm at both implants and adjacent tooth surfaces. The horizontal distance between an implant and the facing tooth did not influence the amount of marginal bone loss that had occurred. In most inter-proximal units, more advanced bone loss (>1 mm, >2 mm) had ensued either at the implant or at the facing tooth surface. Advanced additional bone loss occurred at both the implant and the tooth in only about 3% of the examined subjects.

Conclusion: Bone loss at implants and teeth appears to be a site-specific phenomenon and not dependent on the inter-proximal distance.
