598 Theories and techniques of oral implantology

lize a few of his remaining weak anterior teeth (Fig. 13-34), and vent-plants were used posteriorly in both edentulous areas (Fig. 13-35). A full arch acrylic-and-gold fixed denture was then fabricated and cemented into position with hard cement (Fig. 13-36). Fig. 13-37 shows the intraoral radiographs.

Other cases of stabilizing anterior mandibular teeth with endodontic implants and using other types of endosseous implants laterally are shown in Fig. 13-38. Note that the type of prosthodontic implant selected is determined by the local anatomy of the site.

In cases where insufficient bone exists to use

endosseous implants with endodontically stabilized natural teeth, subperiosteal implants may be suit-able. Several unilateral, finger type subperiosteal implants have been used successfully in combination with endodontic root stabilizers to help support a fixed denture (Fig. 13-39) .

Another unique combination of endodontic pin implants with other types of implants is seen in the case of a woman well into her seventies. This patient had been wearing a partial denture that utilized her remaining two lower bicuspid teeth as the abutments. She was in constant pain because the denture rested on an extremely thin knife-edge
