Therefore, the statistics of mandibular prosthetics show 100 per cent success for these 16 patients. The next 69-year-old patient suffers from extreme maxillary atrophy class VI.7 In such extreme cases, they used to perform Horseshoe Le Fort I osteotomy using interpositional bone grafts from the iliac crest —a very complex surgery under endotracheal anaes- thesia.13,14 We, in contrast, inserted two 4.0 x 5.0 mm short and two 3.0 x 8.0 mm Bicon implants in a very brief procedure under local anaesthesia (Fig. 26). Twelve-piece TRINIA™ prostheses were integrated in the maxilla too (Fig. 27). To position the abutments easier, you can use a positioning splint made of light- cure GC plastic, on which the dental technician indi- cates the most favourable insertion sequence for the abutments (Fig. 28). The patients enjoy prosthetics that leave the palate free (Fig. 29). The prosthesis is either cemented, screwed or telescoped via the four 26 implants 1 2017
