Critical analysis of the literature clearly shows how the implant treatment is reliable and routine with high long-term success rates, for both partial and complete edentulism (Hoffmann et al. 2012). The main causes of implant failure are associated with poor and / or insufficient height and thickness of residual alveolar bone (Davarpanah et al. 1995). The use of implantology can be complex in cases with defects of a vertical and horizontal morphology of the alveolar bone in the lateral-posterior regions of the maxilla and of the mandible (Renouard et al. 2006). Indeed, unfavorable local bone conditions due to atrophy, periodontal disease and traumatic sequelae can result in an insufficient bone volume with vertical, horizontal and sagittal intermaxillary relationships, potentially complicating the functional and aesthetic result (Chiapasco et al. 2009). In the upper jaw, bone quantity is influenced by the degree of reabsorption of the alveolar ridge and by the size of the maxillary sinus; both factors may represent an obstacle to primary implant stability (Bergh et al. 2000, Ulm et al. 1998). The most commonly used augmentation method for maxillary sinus reconstruction with lateral window access was presented by Tatum and published by Boyne and James (Tatum 1986, Boyne and James 1980). We then tried to develop a less invasive surgical technique through the use of osteotomes (Tatum 1986, Summers 1995). This technique involves a crestal approach with a minimal contact of the osteotome with the Schneider membrane, minimizing complications. The advantage of this procedure is the possibility of being able to position the implants simultaneously (Bruschi et al 1998, Zitzmann et al., 1998). The goal of this article is to highlight, through a clinical case, the effectiveness and simplicity of using the new “Duravit Crestal Sinus Lift” method of the B&B Dental Implant Company in cases where the maxillary bone availability is insufficient for implant prosthetic rehabilitation (Bortolini S. et al. 2013, 2014).
