This review of platform-switching of dental implants included 17 RCTs and found that bone loss was lower than in regular platform implants, mean difference = -0.41mm (95%CI; -0.58 to -0.24) with no difference in failure rates RR = 1.10 (95%CI; 0.6–2.02).

This review compared dental implant outcomes in smokers and non-smokers. 15 studies (5 prospective and 10 retrospective) were included which suggest that the odds of implant failure are higher in smokers . OR = 1.96 (95% CI; 1.68–2.30), as is the amount of marginal bone loss.
