      An unconventional technique was used to address the challenge of exposed dental implant threads. Titanium dental implants were prepared with rotary instruments to eliminate the exposed threads and to receive a fixed cementable prosthesis. The technique required fabrication of a gold casting of 2 copings connected by a round bar to fit the prepared implants and an implant-retained overdenture. This technique may be applied to other situations when multiple implants present with thread exposure and bone resorption. These include single crowns, partial fixed dental prostheses, and attachments for overdentures.
