Core Tip
Core Tip: Severe maxillary atrophy limits the predictability of conventional implant-supported full-mouth rehabilitation. This case report demonstrates a prosthetically driven strategy integrating zygomatic and nasalis implants to overcome the biomechanical limitations of posterior-only anchorage. Enhanced anteroposterior spread enables immediate loading while reducing cantilever forces and improving prosthetic stability, function, and esthetics. The digitally guided workflow and stepwise clinical protocol presented offer a reliable graftless solution for managing complex maxillary atrophy and improving patient comfort and quality of life.
