Posterior maxillary atrophy as a result of the loss of dental elements is a rather frequent condition in clinical practice. Its management, in anticipation of the rehabilitation of the patient through an implant-supported prosthesis, requires a careful evaluation of the sinus anatomy, as well as a rational choice of rehabilitative surgical technique. A correct anamnesis, an adequate planning of the intervention and an adequate choice of biomaterials and implants are therefore essential requirements. Among the most frequent surgical approaches in the rehabilitation of the atrophic posterior maxilla, sinus elevation has been the subject of numerous studies and is now considered a safe, effective and predictable procedure. Crestal sinus lift can be associated with techniques aimed at atraumatically lifting the sinus membrane prior to grafting the chosen bone substitute. Grafting biomaterials in semi-fluid or pasty form can further promote homogeneous filling of the space below the sinus membrane and help reduce the risk of perforation. Here we report the use of a new generation bone paste to increase bone volume in the posterior maxillary sectors through sinus lift.
