The featured article for this issue of JOMI represents a long-term, well-populated study that assessed implants that were removed over an 18 year time period. The fact that such an article could be developed is a demonstration that an implant database, in this case the Finnish Dental Implant Register, can serve a valuable purpose. The retrospective study design is subject to bias; however, the large number of included patients may compensate for this potential design flaw. Indeed, the information gained from this article differs from most controlled clinical trials; however, the ability to consider both approaches enhances our knowledge base.
