Progressive bone loss and bleeding on probing: A cohort study

Area of Science:

• Dental Implantology
• Periodontology
• Radiology

Background:

• Progressive marginal bone loss (PMBL) beyond initial bone remodeling (IBR) is a concern in dental implantology.
• Bleeding on probing (BOP) is a common indicator of periodontal inflammation.

Purpose of the Study:

• To determine if progressive marginal bone loss (PMBL) in bone-level implants is associated with bleeding on probing (BOP).

Main Methods:

• Retrospective analysis of 112 implants in 70 patients over 15 years.
• Radiographic assessment of marginal bone levels (IBR and PMBL).
• Recording of bleeding on probing (BOP) at multiple time points.

Main Results:

• 66% of implants exhibited PMBL.
• PMBL was comparable between implants with and without BOP.
• BOP intensity correlated with PMBL at 1 year but not at 5, 10, or 15 years.

Conclusions:

• Progressive bone loss at implant sites is not always linked with bleeding on probing.
• The association between BOP and PMBL may be time-dependent.
