452 Theories and techniques of oral implantology

Fig. 10-247. The template was then fitted in the mouth. (From Linkow, L. I.: Prefabricated endosseous implant prostheses, Dent. Concepts 10 [3] :2-10, 1967.)

Fig. 10-248. The template was secured to the implants by screwing the small set screws through it.

Fig. 10-249. Posteriorly, pin implants were driven through the predetermined holes in the template to avoid the low floor of the maxillary sinus.

Fig. 10-250. The pins were secured to each other with acrylic cores that were prepared for full crown coverage.

vertical extensions of the template so that they were flush with it (Fig. 10-246). The template was tried in the patient's mouth (Fig. 10-247), and the small set screws were inserted through the template and into the internal threads of the implants (Fig. 10-248).

The triplant pins were then drilled posteriorly through predetermined holes in the template and the excess length cut away (Fig. 10-249). The terminal ends of the pins were joined with quick cure acrylic, and the hardened acrylic cores were then prepared for full crown preparations (Fig. 10-250).

An elastic impression of the maxilla and a wax interocclusal record of centric relation were taken. The full arch acrylic-over-gold splint was processed and cemented into position with a hard cement (Fig. 10-251). A Panorex reveals the entire case (Fig. 10-252).
