Risk factors associated with early implant failure: A 5-year retrospective clinical study

Area of Science:

• Dental Implantology
• Periodontology
• Biomaterials Science

Background:

• Dental implants are a common tooth replacement solution.
• Early implant failure poses a significant challenge, with associated factors needing further documentation.
• Optimizing osseointegration is crucial for predictable outcomes and minimizing failures.

Purpose of the Study:

• To retrospectively investigate risk factors associated with early dental implant failure.
• To identify key variables influencing the success of dental implant procedures.

Main Methods:

• Retrospective clinical study of 276 external connection BTI implants in 142 participants (2007-2011).
• Analysis of participant, implant, intervention, and postoperative variables.
• Multilevel logistic regression model used to determine variable influence on early implant failure.

Main Results:

• Early implant failure significantly correlated with male sex (P=.001).
• Severe periodontal disease (P=.005), short implants (P=.001), and bone expansion techniques (P=.002) were associated with failure.
• Postoperative pain/inflammation at 1 week (P<.001) strongly predicted early implant failure.

Conclusions:

• Early dental implant failure is more prevalent in males.
• Severe periodontal disease and the use of bone expansion techniques are linked to higher failure rates.
• Short implants and early postoperative pain/inflammation are significant indicators of potential early implant failure.
