Fig. 15-25. The intermaxillary space was posteriorly divided equally by first lengthening the maxillary castings to one-half the distance.

Fig. 15-26. The completed maxillary prosthesis included two posterior quadrants constructed of gold occlusal acrylic veneers and the anterior quadrant, which consisted of porcelain fused to metal. The posterior quadrants engaged with the anterior quadrant with gold dovetail interlocks. The interocclusal space between the new bridgework and the old lower restorations will then be closed by lengthening the lower restorations.
