In the rehabilitation of atrophic posterior maxilla, factors such as age, extraction of teeth result in loss of alveolar bone height together with increased pneumatization of sinus contradicting the implant surgery. Although adequate bone height can be achieved using various maxillary sinus augmentation techniques, these procedures have been practiced successfully. However, significant complications occur such as perforations or tearing. To maintain the integrity of Schneiderian membrane, subsequently increasing the success rate, a retrospective analysis is carried out on various techniques with complications which occur during and after treatment.After reviewing various sinus elevation techniques: nasal suction technique(NaSucT), balloon antral elevation technique(BAOSFE), and Hydraulic Sinus Lift technique(HySiLift) emerge to be the most favorable among all and can efficiently lift the Schneiderian membrane with minimal trauma. We must emphasize that these are new techniques and they cannot replace the conventional techniques as a whole.
