Abstract: This case series evaluates and compares the clinical outcomes of three different graft materials including xenograft, alloplast, and allograft, used in direct sinus lift procedures for posterior maxillary augmentation. Three patients presenting with severely resorbed posterior maxilla and inadequate residual bone height underwent lateral window sinus lift surgery using one of the three graft types. Post-operative assessment over a six-month healing period included radiographic evaluation of bone height gain and clinical stability at the implant placement stage. All graft types supported satisfactory bone regeneration, with xenograft achieving the highest bone height gain and volume stability, followed by alloplast and allograft. These results align with published evidence favoring xenografts for their osteoconductive properties and long-term stability, while also confirming the suitability of alloplasts and allografts in selected cases. Careful case selection, surgical precision, and compliance with post-operative care protocols were critical to achieving favorable outcomes
