Volumetric Analysis of Maxillary Sinus After Guided Lateral Sinus Lift Procedure With Simultaneous Implant Placement

In Group 1; The surgical procedure began with the adaptation of a prefabricated guide to the surgical site, ensuring firm stabilization. Implant positions were marked, and after the removal of the guide, a crestal incision was made. A mucoperiosteal flap was reflected, exposing the maxillary sinus and alveolar crest. The guide was readapted, marking implant positions, and a lateral window was formed using a bur or piezotome. Sinus membrane elevation was performed carefully. Implants were placed with graft material beneath the elevated membrane. In cases of bony plate preservation, the window was covered. In Group 2 (Lateral Maxillary Sinus Floor Elevation without a surgical guide), a crestal incision and mucoperiosteal flap exposed the sinus. A bony window was created, and careful elevation of the sinus floor followed. Implant osteotomies were completed, and graft material was packed into the sinus. A resorbable membrane was applied, and the flap was sutured. NanoboneÒ was used as the standard graft material in both groups.
