use of CBCT and CAD/CAM cone beam supplement | Fig. 9: Scanned abutments at the frontal section for the sake of designing telescopic crowns. Fig. 10: A design of primary telescopic crowns from zirconium oxide. Fig. 11: Transparency on to make the thickness of the walls of the crowns visible along with the position of the abutments. Fig. 12: Secondary telescopic crowns made from acetal resin prior to being Fig. 15 glued into the construction. Fig. 13: Primary telescopic crowns made from zirconia, packed and designated. Fig. 14 Fig. 16 Fig. 17 Fig. 18 Fig. 20 anchored into the bone at the lateral section, partially within the augmentation material while primary stability was achieved, we decided to ex- pose implants at lateral sections without occlusal load so as to perform the so-called bone training with a view to improving the condition of the bone being regenerated. An impression was taken (Figs. 7 & 8) for the positional model and for the preparation of the temporary prosthesis based on telescopes. Fig. 14: Transfer of abutments from Fig. 19 the model to the mouth by means of pattern resin. Fig. 15: Tightened abutments prior to the mounting of primary telescopic crowns. Fig. 16: Temporary telescopic prosthesis, of skeletal type. Fig. 17: Temporary telescopic prosthesis of skeletal type: inside of the denture. Fig. 18: Mounted primary telescopic Fig. 21 crowns made from zirconia, on abutments. Fig. 19: Test of secondary telescopic crowns made from acetal resin.
