388 Theories and techniques of oral implantology

Fig. 10-4. The pin implants are slowly driven through the template in their predetermined directions in order to circumvent the maxillary sinus in an anteroposterior direction.

Fig. 10-5. The ends of the pins are fused to each other with cold cure acrylic resin.

Fig. 10-6. The hardened acrylic core is prepared for a full crown restoration, making sure it follows the peripheral outline of the gold template.

Fig. 10-7. The interocclusal clearance between the prepared acrylic core and the opposing lower tooth is determined by having the patient bite in centric relation.

Fig. 10-8. From an elastic impression and wax interocclusal record of centric relation, the completed (one-piece casting) superstructure is fitted into position over the acrylic core and gold post extending from the template.

Fig. 10-9. The superstructure is cemented.
