Abstract
BACKGROUND
Severe maxillary atrophy complicates implant-supported full-mouth rehabilitation and often precludes conventional implant placement. Although zygomatic implants provide a graftless posterior anchorage option, limited anteroposterior spread may compromise prosthetic biomechanics. This case report highlights a prosthetically driven approach combining zygomatic and nasalis implants to enhance biomechanical support, optimize load distribution, and enable immediate loading with improved functional and esthetic outcomes.
CASE SUMMARY
A 55-year-old woman presented with partial edentulism of the maxilla and the mandible, seeking fixed dental rehabilitation. Clinical and radiographic evaluation demonstrated severe maxillary atrophy. A full-mouth implant-supported rehabilitation was planned using bilateral zygomatic implants for posterior maxillary anchorage, supplemented with nasalis implants to improve anteroposterior distribution, along with conventional implants in the mandible. A prosthetically driven digital workflow enabled immediate loading. The combined implant strategy enhanced prosthetic stability, reduced cantilever forces, and restored facial esthetics. The patient achieved satisfactory functional and esthetic outcomes with improved comfort and quality of life during follow-up.
CONCLUSION
Strategic integration of zygomatic and nasalis implants enables predictable, biomechanically stable full-mouth rehabilitation in severe maxillary atrophy.
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.
