The left premolars (#24 and #25) were buccopalatally malaligned and exhibited a poor periodontal prognosis. Radiographic examination revealed poor\u2010prognosis premolars, advanced ridge atrophy, and sinus pneumatization, with a residual bone height &lt;\u20096\u2009mm. Initial alveolar ridge preservation was performed, but vertical bone gain remained insufficient after 6 months.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Intervention<\/jats:title>\n                    <jats:p>Following extraction of the premolars, socket preservation with bone grafting and a barrier membrane was performed. Implant placement was performed using a minimally invasive crestal sinus floor elevation with simultaneous grafting, achieving vertical bone augmentation and primary stability. Standard OSSTEM implants (4.5\/11 and 4.5\/10\u2009mm) were used. After osseointegration, staged peri\u2010implant soft\u2010tissue augmentation increased keratinized mucosa width and mucosal thickness to improve tissue stability. The implants were restored with delayed\u2010loading, screw\u2010retained metal\u2010ceramic single crowns following complete soft\u2010tissue maturation.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The staged protocol achieved stable vertical bone gain, healthy peri\u2010implant soft tissues, and successful functional and esthetic rehabilitation. These outcomes were maintained at the 2\u2010year follow\u2010up after crown delivery, with no biological or prosthetic complications, stable marginal bone levels, a favorable emergence profile, and high patient satisfaction.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Sequential alveolar ridge preservation, minimally invasive crestal sinus elevation, and delayed soft\u2010tissue augmentation provide a safe, predictable approach for atrophic posterior maxillary sites.
