Title of Presentation:
Zygomatic vs psi for rehabilitation of severely atrophic maxilla

Abstract Summary:

Direct sinus lifts procedures provide a good alternative but they dont provide the benefit of immediate loading
In recent years use of zygomatic implants n patient specific implants have gained attention in rehabilitating maxillary arch with advantage of immediate loading restoration. But the option of using either depends on careful diagnosis n treatment planning to gain optimal outcome for the patient.

Key Takeaway Points:
1. Treatment options for severely ateophied maxilla that provides immediate loading
2. Treatment options for cases with maxillectormy
3. Pros n cons of zygomatic n patient specific implants
4. Indications of using each technique.

Rehabilitation of a case that has undergone lefort 3 osteotomy in younger age n has failed maxillary implants.
