**5.4 Lateral sinus lift with sticky bone coupled with a simultaneous implant placement**

Tooth loss results in bone resorption. In the transcanine sector of the maxilla, the most characteristic consequence of tooth loss is the lowering of the maxillary sinus, which imposes unfavorable conditions for implant placement. In the cases when the indication for implant placement exists, whereby the height of the remaining bone is less than 5 mm, a lateral sinus lift procedure is done. In this example (**Figure 13**), lateral sinus lift with sticky bone and PRF membrane usage coupled with three dental implant placements was done in a single visit. At the end of the osteointegration process, which went without any complications, three single screw-retained crowns were placed.
