Placement of dental implants in the atrophic posterior maxilla is an exigent procedure in the presence of lower maxillary bone height. Numerous clinical procedures and materials have emerged to solve the problem of lower bone volume. The most commonly used surgical intervention for obtaining appropriate bone height prior to the placement of endosseous implants in the posterior maxilla is grafting to the floor of the maxillary sinus. With years of research already being done in lieu of perfecting this technique, it is safe to say that this has become a very predictable procedure. It is of utmost importance that the preoperative evaluations are done perfectly and the most suitable technique is decided accordingly for that particular situation, to improve the prognosis of the treatment. Among various techniques that are used, we concluded that nasal suction technique, balloon antral elevation technique, and Hydraulic Sinus Lift technique prove to be possibly more effective and efficient as they have less perforation rate, less chair-side time, less technique sensitivity, and eliminate the need for extensive instrumentation as compared to the conventional time-consuming techniques.
