Therefore, it is necessary to surgically increase the bone height to obtain sufficient bone height for implantation. The aim of this case was to perform a two-stage lateral approach sinus surgery to create an adequate amount of residual crest for rehabilitation of the severely resorbed posterior maxillary bone and then to allow the use of dental implants of adequate length. A 2-stage lateral approach sinus lifting operation was planned for a patient with insufficient vertical crest height in the region of tooth #26. The patient waited 6 months after the lateral approach sinus lifting operation and Adequate vertical crest height was obtained for implant placement. External sinus lifting is a highly effective technique for increasing vertical bone heigh in atrophic maxillary crests.}, number={1}, publisher={Dicle University}
