Chrcanovic BR, et al. – The aim of this retrospective study was to evaluate the impact of several factors on the prevalence of dental implant failure, with special consideration of the placement of implants by different dental surgeons. Researchers reported that different levels of failure incidence could be observed between the surgeons, occasionally reaching significant levels, however, a direct causal relationship could not be ascertained. They suggested that the surgeons’ technique, skills, and/or judgment could negatively influence implant survival rates.
