There have been recent reports of successful use of fragmented autogenous dentin being used as a graft material in implant dentistry. This may reduce morbidity and the need for a second donor site or for the use of alloplasts or allografts. This article discusses the background, preparation, and use of autogenous dentin as an oral osseous graft material. A series of cases where autogenous dentin is used to graft immediate dental implant sites is presented. After 21 months, one case biopsy showed only bone and no remnant dentin. Pulverized autogenous dentin may be an appropriate graft material in implant dentistry.
