Limited evidence suggests higher risk of dental implant failures in smokers than in nonsmokers
Linda L. Cheng, DDS, FAGD, ABGD
Systematic Review Conclusion
Within the limits of the existing evidence, smokers who undergo dental implant placement may be at a statistically significant increased risk of experiencing implant failure, postoperative infection, and greater marginal bone loss than are nonsmokers.
Critical Summary Assessment
Results from this systematic review of 107 randomized and nonrandomized studies with numerous confounding factors suggest that smokers may be more susceptible to implant loss, postoperative infections, and bone loss than are nonsmokers.
