Abstract

The aim of this umbrella systematic review is to evaluate the success rate and osseointegration of dental implants in patients with a smoking habit. Electronic database searches of PubMed/Medline, Google Scholar, ScienceDirect, Cochrane Library, and EBSCOhost were done from 2006 until August 2024, using medical subject headings (MeSH) terms. Systematic reviews and meta-analyses (SRMAs) investigating the association between smoking and the rate of success of dental implants based on dental implant failure, marginal bone loss, survival, and peri-implant parameters were deemed eligible. The Assessment of Multiple Systematic Reviews Tool 2 (AMSTAR 2) was used to assess the quality of the included SRMAs. Seventeen systematic reviews have been included. In the reviews, 10 studies included meta-analyses (MAs) that evaluated implant failure rate and marginal bone loss. According to the AMSTAR 2 checklist, one review was scored "high," seven reviews were scored "moderate," seven reviews were scored "low," and two reviews were scored "critically low" quality. The strength of evidence suggests a low level of success and high rate of failure of osseointegration of dental implants in smokers. However, the influence of smoking on the rate of dental implant failure seems to be associated with various factors such as peri-implant inflammatory markers, post-operative infections, etc. Inherently, the conclusion of this review is based on a limited number of systematic reviews.
