Periodontally compromised vs. periodontally healthy patients and dental implants: A systematic review and meta-analysis

Smoking and dental implants: A systematic review and meta-analysis

“…First of all, all confounding factors may have affected the long-term outcomes and not just the fact that implants were placed in smokers or nonsmokers, and the impact of these variables on the implant survival rate, postoperative infection, and marginal bone loss [131][132][133][134][135][136][137][138] is difficult to estimate if these confounding factors are not identified separately between the two different procedures in order to perform a meta-regression analysis. The studies included here have a considerable number of confounding factors, and most of the studies, if not all, did not inform how many implant were inserted and survived/lost in several different conditions.…”

Dental implants inserted in fresh extraction sockets versus healed sites: A systematic review and meta-analysis

“…First of all, all confounding factors may have affected the long-term outcomes and not just the fact that implants were placed in fresh extraction sockets patients or in healed sites, and the impact of these variables on the implant survival rate, postoperative infection and marginal bone loss [105][106][107][108][109][110][111] is difficult to estimate if these factors are not identified separately between the two different procedures in order to perform a meta-regression analysis. The lack of control of the confounding factors limited the potential to draw robust conclusions.…”

Can Periimplantitis Be Treated?

“…Longitudinal studies, 29,30 systematic reviews, 5,31-33 and meta-analyses [34][35][36] have stressed that the history of treated periodontitis is a major risk factor in the development of periimplantitis leading to implant loss. Patients with compromised periodontal status were more susceptible to peri-implant diseases compared with periodontally healthy patients with an odds ratio of 3.1 to 4.7 21 and a risk ratio of 2.17.…”
