ridge, which was really the remaining mylohyoid ridge.

The two bicuspid teeth were prepared to their cementoenamel junctions, and endodontic stabilizers were used as additional support (Fig. 13-40). A

Fig. 13-39. Anteriorly are endodontic stabilizers. Posteriorly are bilaterally placed subperiosteal implants that were used for the endentulous areas because there was not enough alveolar bone for endosseous screws or blades.

uniquely designed scalloped template with a specially chosen spring-type stress-breaker attachment was included posteriorly on either side. Anteriorly, an inverted U-shaped bar of gold, with its vertical portion fused to the base of the template, was included (Fig. 13-41). The template was cemented over the gold post copings, which already had been cemented over the two remaining bicuspid teeth (Fig. 13-42).

Three pin type implants were drilled through predetermined holes in the anterior part of the
