The Challenge: The patient, who presents with a history of diabetes, required complete functional and aesthetic rehabilitation due to a failing terminal dentition. During the planning phase for full-arch therapy, radiographic analysis revealed a challenging anatomical presentation in the second quadrant. The anterior wall of the left maxillary sinus extended unusually far forward, reaching the piriform rim. Because of this anatomical restriction, utilizing a standard tilted implant in the premaxilla was not viable; it would have resulted in an inadequate anteroposterior (AP) spread, biomechanically compromising the long-term stability of the final upper prosthesis.
