Fig. 10: Healthy soft tissues. Fig. 11: Note the different geometry between the gingiva and the transfer coping. Impression-taking Fig. 12: Preliminary impression of the provisionals with ana- logs engaged for preliminary cast. Fig. 13: T he preliminary cast mimics the architecture of the soft tissues around the implants. Fig. 14: Application of acrylic resin to the transfer coping will assure the conservation of the soft-tissue profile (starting from a correct preliminary cast, see figure 13). Fig. 16: Detailed view. Fig. 17: Impression made. Note that the new-generation co- pings (pick-up) for the internal connections are very short. Fig. 19: The geometry of the soft tissues around the implants is the same as that of the preliminary cast (see figure 13). Laboratory phase Fig. 20: Final abutment: parallel walls (0°) were created by the dental technician for correct cement-retained restora- tion approach. Fig. 15: U se of the customized coping maintains the previ- ously obtained soft-tissue profile. Fig. 18: Electroplated impression phase. The cast is construc- ted using an electrodeposited metal and a highly sta- ble epoxy resin able to reproduce details with an accu- racy of 0.2 µm. Fig. 21: An antirotational abutment positioning key is fabri- cated from acrylic resin, and a 20 Ncm torque is ap- plied to reduce spatial inconsistencies.
