Indirect Sinus Lift

Dental implant rehabilitation of the posterior maxillary region has always been a challenging issue due to both alveolar ridge atrophy and sinus pneumatization. To date, various techniques have been described based on the physiology of intrasinus bone repair to obtain better outcomes. Nevertheless, these procedures could also be associated with several intra- and postoperative complications such as perforation of the sinus membrane, hemorrhage, infection, graft resorption, and loss of the graft or implants. However prevention and management of these complications is necessary with thorough knowledge of anatomy of maxillary sinus and surrounding vital structures. It is also mandatory for a prudent clinician to learn well about the direct and indirect maxillary sinus grafting techniques in order to minimize the number of complications associated with it.
