Implant Placement and Immediate Final Rehabilitation

The framework was then trimmed and fitted pas- sively to the model. To transfer the tooth positions from the wax-up, a small amount of sticky wax was used to secure the teeth in the putty matrix, which was then placed on the master cast and filled with wax (Fig. 66). This is a simple and quick way of adopt- ing the set-up from the aesthetic try-in. After com- pleting the wax-up of the maxillary denture (Fig. 67), the occlusion relative to the mandibular wax-up was checked and refined. The gingival portion of the mandibular rehabilitation must offer access for a brush to cleanse underneath (Fig. 68). The wax-up was then processed into resin. The windows offering access to the prosthetic screws can be clearly seen (Fig. 69). They can be closed intraorally using a cold- curing resin at a later time. Fabrication of the restora- tions was now complete (Fig. 70). EDI Case Studies 16 Fig. 67 Wax-up of the maxillary denture. Fig. 69 Lingual fenestration of the bar sleeves for screw verification.
