Dental implant failure has led to continuous innovations of various implant systems and to different interceptive treatment modalities. These concerns have also led to selection of implant designs that best suit the various types of bone. A checklist has been created to facilitate collection of data on the different factors associated with dental implant failure. The data gathered from this list are the basis of a multinational statistical analysis. This analysis will provide accurate information about the percentage of each element causing implant failure. Different causes of failure, such as host factors, surgical placement, and improper implant selection, were reviewed in Part I of this two-part series. This article discusses failure categories in terms of etiology, failure mode, failure type, failure origin, failure timing, responsible personnel, and different tissue types.
