were taken to make a gold occlusal acrylic veneer full arch fixed denture (Fig. 10-35). The prosthesis was then fitted (Fig. 10-36) and cemented with hard cement (Fig. 10-37). A lateral plate roentgenogram shows the vent-plant, spiral-shaft implant, and triplant (Fig. 10-38) .

Fig. 10-33. A vent-plant and a spiral-post implant are seen in position.

Fig. 10-34. A prepared acrylic core affixing the posterior triplant is seen behind the spiral-post implant.

Fig. 10-35. A one-piece full arch fixed denture is fabricated.

Fig. 10-36. The bridge is fitted into position and last-minute adjustments in occlusion and gingival adaptation are done prior to its cementation. All three dissimilar metals plus the gold showed no evidence of galvanic action. The case is still functioning after 6 years.
