A technique for intraradicular dental implants.
A technique utilizing nonvital roots for the support of intraradicular dental implants has been developed and tested. Using this technique it may be possible to preserve the roots of teeth that would normally be lost because of periodontal involvement. In this technique, a suitable tooth is treated endodontically. The crown is then removed to the height of the alveolar crest, and the root is drilled and tapped to accept a threaded stainless steel Heli-Coil insert. The root is then covered with a gingival flap. This allows for the regeneration of periodontal tissues around the root while it isolated from the oral environment. Following the period of natural healing, a stainless steel post is threaded into the Heli-Coil root implant. In the present studies (canine roots in a rhesus monkey) the implant posts are fitted with Adaptic crowns. These implants have been in place for more than 6 months with no sign of implant failure.
