Superfícies texturizadas aumentam as taxas de sobrevivência de implantes dentários em pacientes fumantes? uma revisão sistemática e metanálise

Abstract

Some studies have already stated that the survival rates of dental implants are lower in smokers. Since the establishment of osseointgrated dental implants to the present day many technologies have been developed, specially concerning implant macrogeometry, such as the treatment applied to the implant surface. These specific surface treatments aim to acelerate the osseointegration. However, there is no scientific evidence that state the possible influence of different surface treatments on the survival rate of osseointegrated dental implants in smokers. The main purpose of this systematic review was to evaluate the influence of different treatments applied to the surface of dental implants on their survival rates in smokers. Electronic searches were performed in the following databases: PUBMED/MEDLINE, EMBASE. LILACS WEB OF SCIENCE, SCIELO, COCHRANE CENTRAL. The search result was complemented with manual searches in the bibliographic references of the studies included in the review and in the literature and systematic review articles previously published on the topic. Databases of gray literature were also included in the search process. After selecting the records according to the inclusion and exclusion criteria, a table with the data was generated. Two meta-analysis were carried out to assess the proportion of loss of implants with a machined and rough surface and a third to assess the risk of loss of implants in the cohort of the selected studies. Meta-analysis shows a greater tendency to lose implants with smooth surface in smokers, however the difference between rough and smooth surfaces was not statically significant. Further studies are needed for more accurate comparison.
