| industry 38 implants 1 2016 Postoperative effects are moderate and the pain is contained by level-one analgesics (Paracetamol); the symptoms abated within 48 hours. The X-ray controls every four months show stabilised bone volume at the apexes of the implants (Figs. 14 & 15). The patient is then given an appointment to take impressions. Two short pop-in transfers and a closed impression holder were used, with the aim of inserting two separate crowns. A retroalveolar con- trol X-ray was taken, although there was no doubt about the correct positioning of the transfers. Two customised abutments (made by Simeda, Anthogyr) with a juxtagingival homothetic pre paration (Fig. 16) were ordered. The prostho dontist, Christophe Gigandet, made two single ce- ramo-metallic crowns with non-precious metal frameworks (Fig. 19). The abutments were placed in the patient’s mouth and adjusted with strict ad- herence to the gingival contour (Fig. 17). An X-ray was taken to check how well the struc- tures had adapted (Fig. 18). The points of contact and the occlusion were examined. After filling the access cavities of the abutments, the crowns were sealed with glass ionomer cement (GC FujiCEM 2). The juxtagingival limits facilitate an easy and com- plete cleaning of the cement excess. Conclusion The Osteo Safe® mechanised procedure enables better control of the power of impacts in these crestal sinus lift indications. This system signifi- cantly reduces the learning curve as a result of the regularity of the impacts at constant power (non-operator dependent)._ Figs. 14 & 15: Stable bone volume at the implant apex in 26–27.
