The implant substructure, superstructure and temporary acrylic stent are always made together, fig. 329. Notice that posteriorly on both sides of the implant framework there is an open area distal to the last post with no cross over strut distally, as is usually the case, fig. 320. This was to circumvent the most posterior portion of the exposed inferior alveolar nerves. Notice the inferior alveolar nerve is exposed posteriorly only, fig. 331. The implant is carefully fitted, figs. 332, 333, and screwed into place, fig. 334, and sutured, fig. 335. The acrylic stent had to fit accurately, fig. 336. The healing tissues with the superstructure frame, fig. 337, picked up with an alginate impression, fig. 338. Healing was uneventful, fig. 339, and the prosthesis gave the patient
