Collected Implant Cavity Borings Used as Peri-lmplant Osseous Augmentation Material

The placement of titanium dental implants in atrophic alveolar ridges often requires bone augmentation because of the lack of sufficient bone volume. In a preliminary study of 36 patients, collected borings from implant cavities were used as autogenous bone grafts. In approximately one-half of the patients, a Gore-Tex membrane was also applied. The success of this method was controlled in a second operation, when the membrane was removed or peri-implant soft tissue surgery was necessary. A bony lamella developed in most of the controlled cases. These preliminary results show a method of ecycling autogenous bone as graft material by using collected implant cavity borings, which normally would be discarded. The simplicity of this procedure and the avoidance of a second wound site, or even major surgery, favor its clinical application.
