Fig. 10-191. A plaster index was taken, picking up all of the copings.

Fig. 10-193. The mesostructures are fitted in the mouth over the prepared teeth.

Fig. 10-194. Internally threaded vent-plants are screwed into the incisor regions.

Fig. 10-192. A, Two mesostructures are seen on the master stone rnodel. Flanking the mesostructures are the two cast superstructures. B, The superstructures are fitted over the mesostructures.

Fig. 10-195. The superstructures are fitted over the mesostructures for the final impression, which was taken 1 week after the implants were inserted.
